Answer:
x=-7,y=-2
Step-by-step explanation:
2y=-32-4x
y=-16-2x
7x+(-16-2x)=-51
5x-16=-51
5x=-35
x=-7

I filled it in for you, just remember that 200 is 2 times 100, aka 100%
y = (x^2 + 26x) +160 complete the square
y = (x^2 + 26x ) + 160
Split our the constant and use the (b/2)^2
y = (x^2 + 26x + (26/2)^2 ) + 160 - (26/2)^2
since I am adding the new value I must subtract it from the end to keep the balance
y = (x^2 + 26x + 169) + 160 - 169
Now factor parenthesis and combine like terms
y = (x+13)^2 -9 its in the vertex form
C. You take the tip amount devided by 15%. Thats 0.15. You the get the answer 97.20
Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for <em>e</em>
- Distribute -2: -16 + 2e = 2 - e
- Add e to both sides: -16 + 3e = 2
- Add 16 to both sides: 3e = 18
- Divide both sides by 3: e = 6
Step 3: Check
<em>Plug in e to verify it's a solution.</em>
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
