6 0

A change from 45 to 90 represents a positive change (increase) of 100%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = New - Old|Old| × 100%

Percent change = 90 - 45|45| × 100% =

4545 × 100 = 100% (increase)

Where: 45 is the old value and 90 is the new value. In this case we have a positive change (increase) of 100 percent because the new value is greater than the old value.

PLZ ANSWER! REALLY NEED HELP AND WILL MARK BRAINLIEST!!! PLZZZZZ!!!
olga nikolaevna [1]

Answer:

C.

Step-by-step explanation:

1) the slope-interception form of the given line is:

y=s*x+i, where s - the slope, i - interception;

according to the condition it is

y=1/8*x+i;

2) if to substitute the coordinates of the given point (-10;4) into the slope-interception form, then:

4=1/8* (-10)+i, ⇒ i=21/4;

the equation of the given line is:

y=1/8*x+21/4

3) according to the condition the given point with the coordinates (-6;w) belongs to the line. It means, it is possible to substitute its coordinates into the equation, then calculate the value of the 'w':

w=1/8*(-6)+21/4; ⇒ w=9/2.

Answer C. 9/2

Note: the suggested option is not the only.
