Answer:
24
Step-by-step explanation:
Step 1: Define
x = 2
y = 4
16x + 2x² - y²
Step 2: Substitute and Evaluate
16(2) + 2(2)² - 4²
32 + 2(4) - 16
16 + 8

Answer:
(2,2)
Step-by-step explanation:
Given equations
x-3y=-4-------------------------------(1)
y=-3x+8.------------------------------(2)
Substitute 2 in 1. This means use the value of y in equation 1, to replace y
x-3(-3x+8)=-4------------------open brackets
x+9x-24=-4---------------------collect like terms
10x=-4+24
10x=20---------------------------divide by 10 both sides to get value of x
10x/10=20/10=2
x=2------------------------------use value of x in equation (2) to get value of y
y=-3x+8
y=-3(2)+8
y=-6+8=2
solutions
x=2, y=2
Answer:
2/3
Step-by-step explanation:
Idk about the number line circling thing but here is the explanation.
if you see how many out of 24 cookies Angela gave, you see that she gives 16. This is equal to 16/24, which simplifies to 2/3.
Thus, Angela gives 2/3 of her cookies to her neighbor.
