Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
Answer:
D) The population alternates between increasing and decreasing
Step-by-step explanation:
correct on edge
Replace values of n in expression with 1/4.
9(1/4 + 2) - 5(1/4)
Distributive property
9/4 + 2 - 5/4
Rearrange.
2 + 9/4 - 5/4
Subtract.
2 + 4/4
Simplify.
2 + 1
3.
<h3>The expression is equal to 3 when n = 1/4. </h3>
