Answer:
t = 8, t = 4
Step-by-step explanation:
-t² + 12t = 32
-t² + 12t - 32 = 0 (Subtracted 32 on both sides.)
t² - 12t + 32 = 0 (Divided by -1 on both sides.)
(t - 8)(t - 4) = 0 (Factor.)
t - 8 = 0 t - 4 = 0
t = 8 t = 4
Answer:
bill = 6
hoang = 14
Step-by-step explanation:
the following equations can be formed from the question
H = 8 + b eqn 1
h - 2 = 2b eqn 2
make h the subject of the formula in eqn 2
h = 2b + 2
2b + 2 = 8 + b
collect like terms
2b - b = 8 - 2
b = 6
h = 8 + 6 = 14
The fourth answer is correct, the rest are incorrect.
Answer:
(0,-5)
Step-by-step explanation:
The given function is :
We want to find the point where the graph touches the y-axis.
At this y-intercept, the x-value is zero.
So we put x=0 into the equation to obtain:
We evaluate exponents to get:
The function crosses the y-axis at (0,-5).
Answer:
E. 7x
Step-by-step explanation:
3x plus 4x is equal to 7x because they both have the same terms and when added cannot the X of 3x and 4x cannot be joined together .
So they remain the same.
