A vintage car costs $32,000 when purchased. The car increases in value by approximately 7% at the end of each year, x, after it is purchased. Which inequality can be used to find the years the car is worth more than $75,000?
Answers
Answer:
[tex]32000( {1.07}^{x} ) > 75000[/tex]
The required inequality represents the worth of the car more than $75,000 is 32000[1.07]ˣ > 75000.
Given that,
A vintage car costs $32,000 when purchased. The car increases in value by approximately 7% at the end of each year, x, after it is purchased.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
According to the question,
The relationship of the cost of the car after x year,
= 32000[1 + 0.07]ˣ
= 32000[1.07]ˣ
Now, this cost should be more than $75000
So,
32000[1.07]ˣ > $75000
Thus, the required inequality represents the worth of the car more than $75,000 is 32000[1.07]ˣ > 75000.

m-4=2m
Help on two step equations
Answers
Answer:
m = -4
Step-by-step explanation:
You want the solution to the "two step" equation m -4 = 2m.
Two-step equationA "two-step" linear equation is one that can be solved in two steps. The steps in general are ...
addition of somethingmultiplication by somethingThe "inverse" properties of addition and multiplication are used to identify the quantities added or multiplied.
Forms of a two-step equationThere are two forms a two-step equation might take:
ax +b = c
ax +b = cx
You will notice that one side of the equal sign has a sum of two terms: a term with the variable, and a constant term without the variable. The other side of the equation will have one term, which may be either a constant term or a variable term.
First stepThe idea of the first step is to make sure the variable term ends up on one side of the equal sign, and the constant term ends up on the other side.
The parts of the first step are ...
identify the kind of term on the side of the equation with one termidentify the term of the same kind on the other side of the equal signadd the opposite of that identified term to both sides of the equation.For the given equation ...
m - 4 = 2m
The term by itself is a variable term. The variable term on the other side of the equation is "m". The first step will be to add "-m" to both sides of the equation.
m -4 -m = 2m -m . . . . . . -m added to both sides
-4 = m . . . . . . . . . . . . . simplify
Now, we have a variable term (m) on one side of the equal sign, and a constant term (-4) on the other side. This is the desired result of the first step.
Second stepThe idea of the second step is to make the coefficient of the variable be 1. We do that by multiplying both sides of the equation by the reciprocal (inverse) of the coefficient of the variable.
For the equation ...
ax = b
we multiply by the reciprocal of 'a', which is 1/a.
(ax)(1/a) = b(1/a)
x = b/a . . . . . . . . . . . effectively, we're dividing by 'a'
In the given equation, we have ...
-4 = m
which already has a coefficient of 1 on the variable m. This means we're done, and no additional step is actually needed.
The solution is m = -4.
__
Additional comment
There is another form of 2-step equation you may see occasionally:
a(x +b) = c
Solving this can be done by reversing the order of the steps: first divide by the coefficient of x, then subtract the constant.
x +b = c/a
x = (c/a) -b
If the variable term inside parentheses has a coefficient other than 1, it may be useful to eliminate parentheses using the distributive property, then solve like a regular 2-step equation.

Two pedestrians simultaneously left two villages 27 km apart and walked toward each other, meeting after 3 hours. The first pedestrian walked at a speed of 4 km per hour. At what speed (in km per h) did the second pedestrian walk?
Answers
The speed of the second pedestrian is 5 kilometers per hour.
At what speed did the second pedestrian walk?Let's say that the speed of the second pedestrian is S.
We know that the other pedestrian walks at a speed of 4km/h, and they (together) travel a distance of 27km in 3 hours, then we can write the linear equation:
(4km/h + S)*3h = 27km
It says that both pedestrians work, together, a total of 27km in 3 hours.
Now we can solve that linear equation for S, to do this, we need to isolate S in the left side of the equation.
4km/h + S = 27km/3h = 9 km/h
S = 9km/h - 4km/h = 5km/h
The speed of the second pedestrian is 5 kilometers per hour.

Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.For this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 247, \sigma = 60[/tex]
For item a, the proportion is the p-value of Z when Z = 167, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (167 - 247)/60
Z = -1.33.
Z = -1.33 has a p-value of 0.0918.
Hence the percentage is of 9.18%.
For item b, the proportion is the p-value of Z when Z = 367, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (367 - 247)/60
Z = 2.
Z = 2 has a p-value of 0.9772.
Hence the percentage is of 97.72%.
For item c, the proportion is one subtracted by the p-value of Z when X = 247, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (247 - 247)/60
Z = 0
Z = 0 has a p-value of 0.5.
Hence the percentage is of 50%.
For item d, the proportion is one subtracted by the p-value of Z when X = 350, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (350 - 247)/60
Z = 1.72
Z = 1.72 has a p-value of 0.9573.
1 - 0.9573 = 0.0427.
Hence the percentage is of 4.27%.
For item e, the proportion is the p-value of Z when Z = 67, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (67 - 247)/60
Z = -3.
Z = -3 has a p-value of 0.0013.
Hence the percentage is of 0.13%.
For item f, the proportion is the p-value of Z when X = 300 subtracted by the p-value of Z when X = 200, hence:
X = 300:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (300 - 247)/60
Z = 0.88.
Z = 0.88 has a p-value of 0.8106.
X = 200:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (200 - 247)/60
Z = -0.78.
Z = -0.78 has a p-value of 0.2177.
0.8106 - 0.2177 = 0.5929.
Hence the percentage is 59.29%.
For item g, the proportion is the p-value of Z when X = 400 subtracted by the p-value of Z when X = 360, hence:
X = 400:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (400 - 247)/60
Z = 2.55.
Z = 2.55 has a p-value of 0.9946.
X = 360:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (360 - 247)/60
Z = 1.88.
Z = 1.88 has a p-value of 0.97.
0.9946 - 0.97 = 0.0246
Hence the percentage is 2.46%.
For items h and i, the distribution is symmetric, hence median = mean and the percentages are of 50%.

Larry and Jason start at the same place and ride their bikes in opposite directions. How far apart, in miles, will Larry and Jason be after riding their bikes for 10 minutes? And Identify the information that is NOT needed to determine how far apart Larry and Jason will be after riding their bikes for 10 minutes.
Answers
After riding their bikes, Larry and Jason will be 3.5 miles apart after 10 minutes of their start.
We have Larry and Jason riding their bikes at the speed of 12 miles/hr and 9 miles/hr respectively in opposite directions.
We have to determine how far apart, in miles, will Larry and Jason be after riding their bikes for 10 minutes.
How will you calculate the distance traversed by a body ?The distance travelled can be calculated using the formula -
distance = speed x time
According to the question -
Average speed of Larry = 12 miles/hr
The distance covered by Larry in 10 minutes = d [1] = 12 x 10/60 =
2 miles.
Average speed of Jason = 9 miles/hr
The distance covered by Jason in 10 minutes = d [2] = 9 x 10/60 =
1.5 miles.
Distance between Jason and Larry after 10 minutes -
d[1] + d[2] = 2 + 1.5 = 3.5 miles.
Hence, Larry and Jason will be 3.5 miles apart after 10 min of riding in the opposite directions.

Angle Addition Postulate is the measure of the larger angle is the sum of the measures of the two smaller angles.
Substitution postulate states that a quantity may be substituted for its equality in any expression.
Then substitute the angle measurements into the resulting equation to find, m∠POS:
m∠POQ + m∠QOR = m∠POR (by angle addition)
m∠POR + m∠ROS = m∠POS (by substitution)
m∠POS = m∠POQ + m∠QOR + m∠ROS

And since the standard form of conversion of functions into coordinate points goes as [y = f(x)], i.e., the ordinate is a function of the abscissa, therefore in this case, [y = c(x) = 94].
Thus, we can consider (x₁, y₁) as (0, 94).
Similarly, at 2004, [x = (2004-1990) = 14], and c(x) = 290, i.e.,
We can consider as (x₂, y₂) as (14, 290).
Using the values of (x₁, y₁) and (x₂, y₂), in the above mentioned standard equation of line passing through two points, we get,
[tex](y-94)=\frac{290-94}{14-0} (x-0)\\or, (y-94)=\frac{196}{14}x\\or,(y-94)=14x\\or,y=14x+94[/tex].
Hence, the linear function c(x) that represents the cost of tuition as a function of "the number of years since 1990", denoted by "x" is [tex][c(x) = 14x+94][/tex].
