Answer:
4x-18
Step-by-step explanation:
-6(-x + 3)–2x
first u expand =6x-18-2x
then u add up the like terms
30% of 80
30% = 0.3
0.3 • 80 is the same as 30% of 80.
0.3 • 80 = 24
30% of 80 is 24.
Hope this helps!
Answer:

Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

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

take the points
(0,2.5) and (100,97.5)
substitute in the formula



Find the y-intercept b
we have


substitute i the linear equation 

solve for b

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
