Which expression is equivalent to |8|+|-7|?
Answer: 15
Step-by-step explanation:
|8|+|-7|=
8+7=15 ==> anything inside the absolute value symbol is always positive.
Answer: 8+7
The | | symbol means how far it is from 0 on the number line. -7 is still only 7 away from 0. Now, if you have -|8|, you apply that - to the 8, so then it's -8.

Ralph wants to join a travel soccer team, a discretionary expense.
His parents tell him he must get a job to earn the money to cover the costs. Ralph now views this discretionary expense as an essential expense since he must pay his parents back. The costs of the travel team are listed below.
Uniform - $67.00
Registration - $50.00
Tournaments -$775.00
Travel - $300.00
a. Find the total cost of being on the team.
b. If Ralph takes a summer job and works 10 weeks over the summer, how much must he average each week to cover the travel team expenses?
c. If Ralph is paid at a flat rate of exactly q dollars each week, what is the standard deviation of the distribution of his 10 weekly paychecks?
a) The total cost of being on the team is; $1192
b) Ralph average cost is; $119.20
c) The standard deviation of the distribution of his 10 weekly paychecks is; $0
What is the Total Cost?
We are given the costs of the travel team as listed below;
Uniform - $67.00
Registration - $50.00
Tournaments -$775.00
Travel - $300.00
a) To find the total cost of being on the team, we will simply add all the individual costs as given to get;
Total Cost = 67 + 50 + 775 + 300
Total Cost = $1192
b) If Ralph takes a summer job and works 10 weeks over the summer, then his average cost is;
Average Cost = 1192/10
Average Cost = $119.20
c) If he is paid at a flat rate of exactly q dollars each week, the standard deviation of the distribution of his 10 weekly paychecks is;
$0

Which is one condition that must be present for an inverse relation to be a function?
A. The function must be a straight line. The function must be a straight line.
B. The function must pass the vertical line test. The function must pass the vertical line test.
C. The inverse relation must be a straight line. The inverse relation must be a straight line.
D. The inverse relation must pass the vertical line test.
the correct option is D:
" The inverse relation must pass the vertical line test."
Which is one condition that must be present for an inverse relation to be a function?
Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.
All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.
From this we conclude that the correct option is D:
" The inverse relation must pass the vertical line test."

The circle below is centered at the point (3,-4) and has a radius of length 3.

A. (x-4)² + (y+ 3)² =

B. (x+4)² + (v- 3)² =
32
C. (x-3)² + (y + 4)² = 9
The equation of the circle is given by (C) (x-3)² + (y + 4)² = 9
All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is the separation between any point on the circle and its center.
The equation of the circle in the general form is given by the
(x-a)²+(y-b)²=r²
Where (a,b) is the co-ordinates of the center of the circle and the radius is r.
Now the center of the circle is given at (3,-4) and the radius is r.
We know that the general equation of a circle is [tex]{\displaystyle (x-a)^{2}+(y-b)^{2}=r^{2}}[/tex]
Substituting the values in the equation we get:
(x-3)²+(y-(-4))²=(3)²
or, (x-3)²+(y+4)²=9
Hence the equation of the circle is (x-3)² + (y + 4)² = 9.

statement below true. Show work to justify
your answer.
-5.8+
= a positive number
r
The number that makes the statement is -5.8 + 6.8 = 1 > 0 so, the statement is -5.8 + 6.8 = a positive number is true statement.
The number that makes the statement is,
Based on given conditions , formulate,
-5.8+ _ = a positive number
Let us assume,
We can take positive number is '1'
Then, we can write,
⇒ 1 - (-5.8)
We can negative sign and negative signs are shows to positive sign,
⇒ 1 + 5.8
We can sum or difference in the product,
⇒ 6.8
Hence,
⇒ -5.8 + 6.8
⇒ 1
So, 1 is positive number.
Then, -5.8 + 6.8 = 1 > 0
Therefore, The number that makes the statement is -5.8 + 6.8 = 1 > 0 so,
-5.8 + 6.8 = a positive number.

We are given that;
Its dealers demand at least 30 skateboards per day and 20 pairs of in-line skates per day. The factory can make at most 60 skateboards and 40 pairs of in-line skates per day. The total number of skateboards and pairs of in-line skates cannot exceed 90. The profit of each skateboard is $12 and the profit on each pair of in-line skates is $19
Thus, the inequalities are as follows;
Let x represent number of skateboards
Let y represent in-line skates
Thus;
x ≥ 30
y ≥ 20
x ≤ 60
y ≤ 40
x + y ≤ 90
y ≤ -x + 90
f(x, y) = 12x + 19y
At (30, 20), f(30, 20) = 12(30) + 19(20) = $740
At (30, 40), f(30, 40) = 12(30) + 19(40) = $1120
At (50, 40), f(50, 40) = 12(50) + 19(40) = $1360
At (60, 20), f(60, 20) = 12(60) + 19(20) = $1100
At (60, 30), f(60,30) = 12(60) + 19(30) = $1290

suppose that y varies directly with x and y = -9 when x = 3 write the direct variation that relates to X and Y. y= and find y when x=7
The direct variation is -27/7.
y=27/7 when x= 7
What is variation ?Y= -9 when x = 3 and y varies directly with x which can be written as y directly proportional to x.
[tex]x_{1} /x_{2}[/tex] = [tex]y_{1} /y_{2}[/tex]
3/7 = -9/y2
y2 = - 27/7
A variation is a connection between a set of values for one variable and a different set of values. If m is a nonzero constant and b = 0, the equation y = mx + b yields the function y = mx (often written y = kx), which is known as a direct variation.
The calculus of variations is a branch of mathematical analysis which finds maxima and minima of functionals: mappings from a set of functions to the real numbers. Variations are minor changes in functions and functionals.

12. CONCERT A concert venue surveyed
680 concert attendees about the concession
stand. Of those that visited the concession
stand, 527 said the concession stand prices
are excessive, and the remaining 44 did not.
Write an equation to find the number of
attendees a who did not visit the concession
stand. (Lesson 1-1)
Solving a linear equation, we will see that 109 attendees did not visit the concession stand.
How to find the number of attendees who did not visit the concession stand?
First, we know that the total number of surveyed people is 680.
Of these 680, we know that:
527 said that the concession stand prices are excessive.44 said that the concession stand prices are not excessive.x did not visit the concession stand.Now, the 3 numbers above should add up to the total number of surveyed people.
527 + 44 + x = 680
Solving that linear equation for x:
x = 680 - 527 - 44 = 109
We conclude that the number of attendees who did not visit the concession stand is 109.

Which one of the following compound inequalities has no solution?
From the following compound inequalities, all the compound inequalities have a solution.
What is compound inequality?
A compound inequality is a type of inequality that comprises two basic inequalities.
From the given information, we have:
3x-7 ≤ 5x + 5 and -4x +8 < 5x - 1
-2x+9>4x+3 and-8x-9 < -7x-3
-2(x-9) < 3(x+4) and -4(x-1) > -5(x-2)
3x+1 < 5x+7 and -2x+5 ≤ -5x -10
To determine the compound inequality with no solution, we need to solve each of the inequalities.
1.
3x-7 ≤ 5x + 5 and -4x +8 < 5x - 1
Collect like terms
-7-5 ≤ 5x-3x and 8+1 < 5x+4x
-12 ≤ 2x and 9 <9x
x ≥ -6 and x > 1 (has a solution)
2. -2x+9>4x+3 and-8x-9 < -7x-3
Collect like terms
9-3 > 4x+2x and -9+3 < 8x-7x
6 > 6x and -6 < x
x< 1 and x < -6 (has a solution)
3.
-2(x-9) < 3(x+4) and -4(x-1) > -5(x-2)
Open brackets
= -2x +18 < 3x + 12 and -4x + 4 > -5x +10
Collect like terms
= 2x + 3x > 18 - 12 and 5x-4x > 10 -4
= 5x < 6 and x > 6
= x > 6/5 and x > 6 (has a solution)
4.
3x+1 < 5x+7 and -2x+5 ≤ -5x -10
1-7 < 5x-3x and 5x -2x ≤ -10 +2
-6 < 2x and 3x ≤ -8
x > -3 and x ≤ -8/3 ( has a solution)
Therefore, no compound inequalities has no solution.
