Solve for w i’m just tired of answering these questions on ixl at this point so that’s why i’m here

-2.27 + 9.1w + 1.3w = -3.4w - 17.45

First, combine like terms

-2.27 + (9.1w + 1.3w) = -3.4w - 17.45

-2.27 + 10.4w = -3.4w - 17.45

Add 2.27 to both sides and 3.4w to both sides to isolate the w.

-2.27 (+2.27) + 10.4w (+3.4w) = -3.4w (+3.4w) - 17.45 (+2.27)

10.4w + 3.4w = -17.45 + 2.27

Simplify

13.8w = -15.18

Isolate the w. Divide 13.8 from both sides

13.8w/13.8 = -15.18/13.8

w = -15.18/13.8

w = -1.1

-1.1 should be your answer

hope this helps

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
