${h}^{ - 1} oh(x) = x \\ {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) + \frac{5}{8} = x \\ 8kx + 2km + \frac{5}{8} = x$

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2

If x-y doesn't equal 0 then x^2-y^2 / x-y =

NARA [144]

Recognize the differnce of 2 perfect squares

a²-b²=(a-b)(a+b)

so
$\frac{x^2-y^2}{x-y}=\frac{(x-y)(x+y)}{x-y}=(\frac{x+y}{1})(\frac{x-y}{x-y})=(x+y)(1)=x+y$

What is the interest rate if...<br> Principal = $1,250<br> Time = 4 years<br> Interest = $285.

alexandr402 [8]

Answer:

<h3>The answer is 5.7 %</h3>

Step-by-step explanation:

To find the rate given the principal , time and interest , we use the formula

$r = \frac{100I}{pt} \\$

where

p is the principal

t is the time

I is the interest

From the question

Principal = $1,250

Time = 4 years

Interest = $285

We have

$r = \frac{285 \times 100}{4 \times 1250} = \frac{28500}{5000} = \frac{285}{50} \\ = 5.7$

We have the final answer as

Hope this helps you
