Answer:
10%
Step-by-step explanation:
In this question, we are asked to calculate the percentage error in a measurement.
This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6
The percentage error is thus 0.6/9.5 * 100 = 6%
The value is actually 10% to the nearest tenth of a percent

Answer: C
Step-by-step explanation:
Convert all equations into slope-intercept form, the equation must have a slope of 1/4 and a y-intercept of -2
A) x + 4y = -8
4 ÷ (4y = - x - 8) ÷ 4
y = -1/4x - 2 --> Not the correct equation because slope is negative
B) 4x - y = 2
-1 ÷ (- y = 2 - 4x) ÷ -1
y = 4x - 2 --> Not the correct equation as the slope is not a fraction
C) x - 4y = 8
-4y = 8 - x
-4 ÷ (x - 4y = 8) ÷ -4
y = 1/4x - 2 --> Therefore, C is the correct equation
