Answer:
answer is A. (f.g) (x) = 6x
Answer:
25 minutes 42 seconds
Step-by-step explanation:
The tub will fill at the rate of ...
2.25 gal/min - 0.50 gal/min = 1.75 gal/min
It will take ...
45 gal/(1.75 gal/min) ≈ 25.714 min
for the tub to fill.
You can shower for about 25 minutes 42 seconds.
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
(180 * 2) * 3 + 200 * 2
360 * 3 + 400
1080 + 400 = 1480 feet
Answer:
D. Rewrite one side (or both) using the distributive property, Yes
Step-by-step explanation:
How can we get Equation BBB from Equation AAA? Based on the previous answer, are the equations equivalent? In other words, do they have the same solution?
