Answer: 40%

Step-by-step explanation:

Let the percentage of 22 that gives 8.8 = x% ---------------------------1

Therefore,

x% of 22 = x/100 x 22 ------------------2

since this gives 8.8, we now equate to equation 2

x/100 x 22 = 8.8

(22 x X )/100 = 8.8

22x/100 = 8,8

Now cross multiply to solve for x

22x = 8.8 x 100

22x = 880

Now divide through by 22 to get the require value of x

x = 880/22

x = 40%

If f(x) = x2 + 3x - 4, find f(4).

Nat2105 [25]

Answer:

f(4) = 24

Step-by-step explanation:

Plug in 4 for x in the equation:

f(x) = x² + 3x - 4

f(4) = (4)² + 3(4) - 4

Remember to follow PEMDAS. PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

and is the order of operation.

First, solve the power:

(4)² = 4 * 4 = 16

Next, multiply 3 with 4:

3 * 4 = 12

Next, combine the terms:

f(4) = 16 + 12 - 4

f(4) = (16 + 12) - 4

f(4) = 28 - 4

f(4) = 24

f(4) = 24 is your answer.

PLEASE HELP

Leto [7]

Answer:

N = -2M + 110

Step-by-step explanation:

Use the point (70, 20) and (50, 30) to find the slope. Use rise/run.

You go down 20 and right 10, so the rise/run is -20/10 which reduces to -2.

To find the y-intercept, go to the y axis and see where the intersects it which is 110.

N = -2M + 110
