Answer:
The answer is -12
Step-by-step explanation:
2xy + 3x + 4x + 3 if x = 5 and y = -5
Now,
2xy + 3x + 4x + 3
2(5)(-5) + 3(5) + 4(5) + 3
-50 + 15 + 20 + 3
38 - 50 = -12
Thus, The answer is -12

4.On Mrs. McIntire’s answer key for the assignment, the correct answer is −0.5. Which student answer(s) is (are) correct? Explain.
Step-by-step explanation:
Answer:
y= 35
Step-by-step explanation:
y directly proportional to x
where x= 2, y= 10
y=kx
10= k× 2
k= 10/2
k= 5
to find y when x is 7
y = kx
y = 5× 7
y= 35
In order to figure this out you need to use slope intercept for for each of these hills. Let's say the first hill is HA and the second hill is B
slope intercept: y = mx + b
HA: y = (2/10)x
HB: y = (2/15)x
As you can see when you plot this on a graph, HB is steeper because the line rises more sharply.
