Si quieres la major superficie posible corta 2 de 48x36
Answer:
30
Step-by-step explanation:
1.Substitute the x for 12.
2.Multiply the 2 by 12.
3.Then add 6 to your answer.
The correct option would be: y = 2x
You can check by replacing the variables with the given values.
Hope this helps!
The formula is y = mx+b where m is the slope and b is the y intercept.
y = 0x + b
7 = (-6)0 + b
7 = 0 + b
b = 7
y = +7
Answer:
x = -1
y = 1
Step-by-step explanation:
y = -x² + 2 (1)
y = x² + 4x + 4 (2)
matching (2) and (1);
-x² + 2 = x² + 4x + 4
-x² - x² - 4x + 2 - 4 = 0
-2x² - 4x - 2 = 0
-x² - 2x - 1 = 0
x² + 2x + 1 = 0
(x + 1)² = 0
x + 1 = 0
x = -1
replacing in (1)
y = - x² + 2
y = - (-1)² + 2
y = -1 + 2
y = 1
Verification;
-x² + 2 = x² + 4x + 4
-(-1)² + 2 = (-1)² + 4(-1) +4
-1 + 2 = 1 - 4 + 4
1 = 1 ✔
