Answer:
Angle 7 or angle DHG
Step-by-step explanation:
Vertical means the opposite angle, or in dictionary definition means each of the pairs of opposite angles made by two intersecting lines. So the vertical angle to angle LHI (angle 9) will be angle DHG (angle 7)

Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws. Each person shoots for an equal amount of time, while the other person rebounds the ball. How long does each person shoot free throws? Write your answer as a proper fraction or mixed number.
Answer:
22¹/₂ minutes
Step-by-step explanation:
If Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws, the total time it takes for the both of them to shoot free throws is 45 minutes.
Let the amount of time Trent and Vivian shoot the free throws be t₁ and t₂ respectively.
Since they both throw at equal times, t₁ = t₂ = t.
Now t₁ + t₂ = 45 the total time it takes to shoot the free throws.
Since, t₁ = t₂ = t.
t₁ + t₂ = 45
substituting t into the equation, we have
t + t = 45
adding the t's, we have
2t = 45
dividing both sides by 2, we have
t = 45/2
t = 22¹/₂ minutes
So, it takes each person 22¹/₂ minutes to shoot free throws.
Answer:
22 1/2 minutes
Step-by-step explanation:
45 divided by two =22 1/2

Of(x) - 2x - 6
O f(x) = 2x + 9
Answer:
[tex]f(x)= -2x + 9[/tex]
Step-by-step explanation:
The table is not properly formatted:
We have:
x ------- y
0 ------- 9
1 ------- 7
2 ------- 5
3 ------- 3
4 ------- 1
Required
Determine the linear equation
Since, it is a linear equation.
We need to first determine the slope.
Take any to corresponding values of x and y
[tex](x_1,y_1) = (0,9)[/tex]
[tex](x_2,y_2) = (4,1)[/tex]
Slope is then calculated as thus:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{9 - 1}{0 - 4}[/tex]
[tex]m = \frac{8}{- 4}[/tex]
[tex]m = -2[/tex]
The linear equation is then calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 9 = -2(x - 0)[/tex]
[tex]y - 9 = -2x[/tex]
Add 9 to both sides
[tex]y - 9 + 9= -2x + 9[/tex]
[tex]y = -2x + 9[/tex]
[tex]f(x)= -2x + 9[/tex]

Anthony charges $15 an hour for tutoring and $10 an hour for babysitting. He can work no more than 14 hours a week. How many hours should Anthony spend on each job if he wants to earn at least $125 each week?
Select a system of inequalities to represent the situation. Let x represent hours of tutoring and y represent hours of babysitting.
A)
x+y≤14; 10x+15y≥125.
B)
x+y≤14; 15x+10y≥125.
C)
x+y≥14; 15x+10y≥125.
D)
x+y≤125; 15x+10y≥14.
Answer:
Step-by-step explanation:
C
The system of inequalities representing the given situation is x + y ≥ 14; 15x + 10y ≥ 125. which is the correct answer would be an option (C)
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the number of hours should he spend on each job if he wants to earn at least $125 each week.
Let the hours of tutoring would be x
And y the hours of babysitting would be y
Given that He can work no more than 14 hours a week.
So inequality as per the above situation is: x + y ≥ 14
Since he charges $15 an hour for tutoring and $10 an hour for babysitting.
If he wants to earn at least $125 each week.
So inequality as per the above situation is: 15x + 10y ≥ 125
Therefore, the correct answer would be option (C).

Answer:10
Step-by-step explanation:
1) 8h – 21 = 7(6 – 4)
Answer:
35/8 or 4.375
Step-by-step explanation:
Distribute the 7
