D is true hope this helps
That’s how you plug it in and get the answer because when you plug in z and y value correctly you just have to follow the rule and simplify
So final answer would be +2
D. As the x-values go to negative infinity, the function's values go to positive infinity.
Step-by-step explanation:
In the diagram you notice as the values of x increase to the far negative value, the function's output values increase to positive infinity.
For example at ;
x=-2, f(x)=0
x=-3, f(x)= 16
x= -4, f(x)= >64
This shows that as x values approach -∞, f(x) approach +∞

Yes they are correct.
At least I'm pretty sure they are:)
Answer:
option D
D. x = 5, y = 2
Step-by-step explanation:
Given in the question two equation,
Equation 1
5.3x + y = 28.5
Equation 2
4.2x + 3.1y = 27.2
rearrange equation 1 in terms of y
y = 28.5 - 5.3x
Substitute the value of y in equation 2
<h3>4.2x + 3.1(28.5 - 5.3x) = 27.2</h3>
4.2x + 88.35 - 16.43x = 27.2
4.2x - 16.43x = 27.2 - 88.35
-12.23x = -61.15
x = 61.15/12.23
x = 5
put value of x in any of the equation
<h3>5.3(5) + y = 28.5</h3>
y = 28.5 - 26.5
y = 2
