Answer:

7

Step-by-step explanation:

We want to evaluate the fraction below for x = 3. We will put the value of x to be 3:

\dfrac{7^2}{x^2-2}\\\\= \dfrac{7^2}{3^2-2}\\\\= \dfrac{49}{9-2}\\\\= \dfrac{49}{7} = 7

The answer is 7.

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.
masha68 [24]

Answer:

y=0.95x+2.5

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take the points

(0,2.5) and (100,97.5)

substitute in the formula

m=\frac{97.5-2.5}{100-0}

m=\frac{95}{100}

m=0.95

Find the y-intercept b

we have

m=0.95

point\ (0,2.5)

substitute i the linear equation  y=mx+b

2.5=0.95(0)+b

solve for b

b=2.5

Note It was not necessary to calculate the value of b because the value is given in the table

Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))

The linear equation is

y=0.95x+2.5
