Answer:
1) Distribute 1.2 to 6.3 and -7x
2)Combine 3.5 and 7.56
3)Subtract 11.06 from both sides
Step-by-step explanation:
3.5 + 1.2(6.3 - 7x) = 9.38
Distribute 1.2 to 6.3 and -7x
3.5 + 1.2* 6.3 - 1.2 * 7x = 9.38
3.5 + 7.56 - 8.4x = 9.38
Combine 3.5 and 7.56
11.06 - 8.4x = 9.38
Subtract 11.06 from both sides
11.06 - 8.4x -11.06 = 9.38 - 11.06
-8.4x = -1.68
To find solution:
Divide both sides by (-8.4)
-8.4x/-8.4 = -1.68/-8.4
x = 0.02
8x(5x2+3)=8x(15+3)=8x13=104
(6/5.55) * 100 = 108.11 %
The percent error is 108.11 %
Answer: 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" the y-intercept.
Since the given line has a y-intercept at (0,-15), then:

The formula for calculate the slope is:

Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:

Substituting values into
, we get that the equation of the line in Slope-Intercept form is:
