wolverine [178]3 years ago
4 0

Answer:

12

Step-by-step explanation:

Set x=0

when you do that, you will find the point where y=12 since x^2+8x=0, but adding the 12 moves up the y-component by 12 units

Alina [70]

Answer:

Let x = the length

Let P = the perimeter of the first pool

48 = (1/3)P

144 feet = P

P = 2l + 2w

144 = 2x + 2(24)

144 = 2x + 48

96 = 2x

48 feet = x

Solve the equation: <br> x - 9 = -6 + 5 <br><br> A. 21<br> B. 7<br> C. 14<br> D. 2
uysha [10]

Answer:

I got 8, but I'm not sure.

Step-by-step explanation:

So I first did -6 + 5, and I got -1 as an answer. Then I did -1 plus 9 because both sides need to be equal. I wrote that x = 8 but that wasn't an option. I'm not sure if this was helpful and I'm really sorry if it's not.

A man is twice as old as his son. Twelve years ago, the man
GrogVix [38]

Answer:

Son's age = 24 years

Man's age = 48 years

Step-by-step explanation:

Let's take the age of son as x

Man's age = 2x

Twelve years ago,

Son's age= x-12

Man's age= 2x-12

Man is three times as old as his son so,

\frac{2x - 12}{x - 12 } =  \frac{3}{1}

Solving for x,

2x-12(1) = x-12(3)

2x-12 = 3x-36

2x-3x = -36+12

-x = - 24

x = 24

So if we substitute the values we get,

Son's age = 24 years

Man's age = 48 years

Hope you understand :)
