Answer:
3
Step-by-step explanation:
An equation typically has a slope. Since there is no equation given, I am assuming that 1/7 is the slope:)
1/7 simplified into decimal form is is 0.1428!
Surface area of a cube = 6l²
Now given length = l = 8 mm
= 6*8² = 6*64 = 384 mm².
Thank you !!
Answer: B. -3 and 7
Step-by-step explanation:
To find the zeros, just move the constants to the other side,
x - 7 ⇒ x = 7
x + 3 ⇒ x = -3
If the number is moved to the other side its sign becomes opposite
Hope it helps!
The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 =
{-5, 3}
