determine the given equation is a liner equation . write yes or no . if yes write the equation in a standard form
7n - 8m = 4-2m
use standard form
Answer:
7n - 8m = 4-2m is a linear equation. Rewritten:
6m + 7n = 4
Step by Step Explanation:
7n - 8m = 4-2m can be simplified by combining terms as if to solve. Add 2m to both sides of the equation..
7n - 8m +2m = 4-2m+2m leaves
7n + 6m = 4
It can be rewritten in slope-intercept form:
n = -6/7 m + 4
Find the value of x in the triangle below.
Answer:
x = 35°
Step-by-step explanation:
Definition of a Line: 180°
Sum of Angles in a Triangle: 180°
Step 1: Find interior angle
125° + z = 180°
z = 55°
Step 2: Find m∠x°
90° + 55° + x° = 180°
145° + x° = 180°
x = 35°

Which of the following functions represents the values in the table below?
x 0 2 4 6
f(x) 2 10 66 218
f(x) = -3x - 2x^2
f(x) = x^2/2
f(x) = 2 + x^3
f(x) = 3x - 2
As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.
Answer: x = 2.
The required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Put x = 0 in every given function,
Then that function that gives 2 will be our required function,
So,
f(x) = 2 + x³.
f(0) = 2 + 0³
f(0) = 2
Thus, the required function that represents the value in the table is f(x) = 2 + x³. Option C is correct.

To avoid a storm, a passenger-jet pilot descended 0.51 mile in 0.6 minute. What was the plane's average change of altitude per minute?
Answer:
The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute

Answer:
c = 29
Step-by-step explanation:
Alright, So from the numbers, we know each side is 7
So overall area is 49
And each triangle is 5(5 x 2/2)
And multiply that by 4 to get 20
49 - 20 is 29
Answer: the length of c is √29
Step-by-step explanation:
The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."
The formula looks like c² = a² + b²
To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.
Square each of those numbers, then add them together.
2² means 2×2=4 and 5² is 5×5=25 4+25 = 29
Now we go into reverse to get the value of c. We have c²=29
So we take the square root of 29 c=√29
That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)
√29 is about 5.385164807.... and it keeps going. Just round it off!
(Some math teachers are fine with leaving the irrational roots as √something)
Apparently, the green answer box for this question needs √29
But it helps if you can associate some nearly rational value to make sense of it.
But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.

Step-by-step explanation:
Tony bought 3 tickets to a concert for $78. How much will it cost for 6 tickets to the concert if all tickets have the same unit price? Use the table below to help determine the missing value:
Number of Tickets 3 4 5 6
Cost $78 $104 $130 ?
(3 points)
Select one:
a.
$136
b.
$146
c.
$156
d.
$234
Answer:
c. $156
Step-by-step explanation:
There are two ways to solve this problem. The first is doubling the first cost as 6 is 2(3). The other way is subtracting the previous number in the sequence with the new one. For example 104-78=26. Then add 26 to 130 and you get 156.

Answer:x>4
Step-by-step explanation:
Answer:
x < 4
Step-by-step explanation:
The answer is 4 because first u get rid of the twelve by adding twelve which you have to do to both sides so it becomes 4x<16. Then you have to divide 16 by four which is equal to four Therefore the answer is 4.
Why does -2.4-(-7)have the same result as -2.4+7? Explain your reasoning.
Answer:
-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.
Step-by-step explanation:
I gave a basic answer. You might have to elaborate more on this.
