Answer:

-384

Step-by-step explanation:

f(x) =x^2+8x

evaluate f(x)=-16

input -16 for x

-16^2+8(-16)

-16^2= -256

then, 8*-16=-128

add the two negatives

-256+-128= -384

Solve the equation 3x + 4y = 16 for x.
Neko [114]

Answer:

3x + 4y = 16  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16  Divide by 3.

x = -4y/3 + 16/3  Answer B.

A mass club has 40 members the number of girls is five less than two times the number of boys how many members are boys how many
Lorico [155]

Answer:

15 boys and 25 girls

Step-by-step explanation:

The sum of boys (b) and girls (g) is given as 40:

g + b = 40

The number of girls is 2 times the number of boys minus 5:

2b - 5 = g

First formula can be rewritten as g = 40 - b

Then you can substitute this for g in the second, and you get:

2b-5 = 40-b

Which simplifies to:

2b + b = 40 + 5

3b = 45

b = 15

g = 40-15 = 25

15 boys, 25 girls.
