Answer: HI!
Step-by-step explanation:
On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.
on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.
combine like terms on the left to get 7x-6=-2x+2
add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.
Answer:
It is the Last answer D
Step-by-step explanation:
because 15/2 is equal to 7 1/2
the square room of 64 is 8
and 8.1444444 is less than 8 1/7
Answer: 
Step-by-step explanation:
Given: Density of tank = 0.4 fish over feet cubed.
We know that, 
Therefore,

Hence, the volume of the tank = 
Parabola equation with a vertex at (h, k) is given by y = a(x - h)^2 + k
For the give parabola, y = a(x - 4)^2 - 3
y = a(x^2 - 8x + 16) - 3
At (5, -6)
-6 = a((5)^2 - 8(5) + 16) - 3 = a(25 - 40 + 16) - 3 = a - 3
a = -6 + 3 = -3
Therefore, the coefficient of the squared expression is -3.
