Graph 2 has opposite expressions
Start by calculating the equations of the functions.
From the graphs, we have the following equations
Graph 1: y = -|2x| + 2Graph 2: y= 2x -2 and y= -2x - 2Graph 3: y = 2x - 1 and y = -2x + 1Graph 4: y = -2x + 1 and y = 2x - 1An opposite function is defined by y = f(x) and y = f(-x)
Graph 1 is an absolute value graph.
Check if y = f(x) and y = f(-x) is true for function 2.
We have:
[tex]f(x) = 2x - 2[/tex]
[tex]f(-x) = 2(-x) - 2[/tex]
[tex]f(-x) = -2(x) - 2[/tex]
For graph 2, f(x) and f(-x) are true.
Hence, graph 2 has opposite expressions

Marcus is considering two car rental plans. Plan A can be modeled with the equation C = 30 d , and Plan B can be modeled with the equation C = 25 d + 15 , where C represents the cost in dollars and d represents the number of days a car is rented. Which statement would justify selecting Plan B instead of Plan A?
Answer: Marcus rents a car for 3 days.
Answer: d. Marcus rents a car for 5 days.
Step-by-step explanation:
If D = the number of days then C=25(5)+15=140(plan b)
C=30(5)=150 (plan a)
Plan b is better because plan b cost less than plan a for 5 days.
Determine the measure of each of the labeled angles given that lines m and n are parallel
Answer:
Step-by-step explanation:
∠1 + 52 = 180 {linear pair}
∠ 1 = 180 - 52
∠1 = 128
∠4 = 52 {Vertically opposite angles}
∠3 = ∠1 {Vertically opposite angles}
∠3 = 128
∠2 + 44 = 180
∠2 = 180 - 44 {linear pair}
∠2 = 136
∠5 = 44 {Vertically opposite angles}
∠6 = ∠2 {Vertically opposite angles}
∠6 = 136
∠11 = ∠2 {corresponding angles}
∠11 = 136
∠12 = 44 {corresponding angles}
∠15 = ∠5 {corresponding angles}
∠15 = 44
∠16 = ∠6 {corresponding angles}
∠16 = 136
∠13 = 52 {corresponding angles}
∠14 = ∠1 {corresponding angles}
∠14 = 128
∠17 = ∠3 {corresponding angles}
∠17 = 128
∠18 = ∠4 {corresponding angles}
∠18 = 52
∠4 + ∠ 5 +∠7 = 180 {angle sum property of triangle}
44 + 52 + ∠7 = 180
96 + ∠7 = 180
∠7 = 180 - 96
∠7 = 84
∠10 = ∠7 {Vertically opposite angles}
∠10 = 84
∠7 + ∠8 = 180 {linear pair}
84 + ∠8 = 180
∠8 = 180 - 84
∠8 = 96
∠9 = ∠8 {Vertically opposite angles}
∠9 = 96
the measures of two sides of a triangle are given. between what 2 numbers must the measure of the third side fall?
a)15 and 18
b)21 and 47
c)64 and 88
Answer:
hmm i think its A
Step-by-step explanation:
The complete question:
What is the range of values of x for a triangle's third side given side measures
of 8 and 15 for the other two sides?
A) Between 8 and 15
B) Between 7 and 23
C) Less than 7, greater than 23
D) Between 8 and 23
Solution:
The measure of third side will fall Between 8 and 23. So Option D is correct.
What is Triangle Inequality Theorem ?The third side of a triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides. This is known as the Triangle Inequality Theorem.
Given that,
The triangle,
whose two sides has length,
8 and 23 unit
So, for a triangle with sides of 8 and 15, the third side must satisfy the following inequality:
7 < x < 23
Therefore, the range of possible values for the third side of the triangle is:
D) Between 8 and 23

Answer:
Obtuse
Step-by-step explanation:
An obtuse angle is anything that is greater than 90 degrees but less than 180. If it was 180 the angle would be flat but if it was 90 it would be right. Because this is in the middle it is obtuse.

-9 + 1/4x - 6 - 1/8x
Answer:
Assuming you want me to simplify your answer, the answer to your question is x/8-15.
Step-by-step explanation:
Simplify each term by combining 1/4 and x, and then combine x and 1/8 to get -9+x/4-6-x/8. Subtract 6 from -9 for x/4-15-x/8. Write x/4 as a fraction with a CD (Common Denominator) by multiplying by 2/2. Write each expression with a CD of 8. Combine the numerators, subract x from x*2 by reordering x and 2 to get 2*x-x/8-15. Then subract x from x to get x/8-15.
