5 yards + 3 yards = 8 yards of fabric. The answer is A. Hope this helps.
The slope-intercept form:
m - slope
b - y-intercept
Convert the equation of the line 4x - 7y = 7x + 4y to the slope-intercept form:
<em>subtract 4x from both sides</em>
<em>subtract 4y from both sides</em>
<em>divide both sides by (-11)</em>
Let and then
We have therefore the slope of the line perpendicular is
Therefore we have:
Put the coordinates of the point (4, -4) to the equation of a line:
<em>subtract from both sides</em>
Answer:
Answer:
90 - 54w
Distribute 18 to both numbers.

Notes:
- At 95% confidence, the z critical value is roughly z = 1.96 which is determined using a Z table.
- E = 0.03 to represent the 3% error.
- We're not told the value of , so we assume the most conservative estimate of 0.5
- <u>Always</u> round up to the nearest integer. The value 1067.111 is closer to 1067, but we round up to 1068 to clear the hurdle needed.
