Answer:
The slope-intercept form is y = 7x + 3
Step-by-step explanation:
Remember: Perpendicular lines slope are negative reciprocals of each other.
y = -1/7x + 4.
Now you know the slope of the given line is -1/7.
So the slope of the perp line is 7/1 = 7 .
Use the given point (-1, -4) and the perp slope = 7 into y =mx + b and solve for "b".
y = mx + b
-4 = 7(-1) + b
-4 = -7 + b
-4 + 7 = b
3 = b
The slope-intercept form is y = 7x + 3
Answer:
143,548
Step-by-step explanation:
When dealing with percentages, use the equation x=p/w, where x is the percentage, p is the part, and w is the whole
plug in the given values: 0.186=26,700/w
multiply each side by w: 0.186w=26,700
divide each side by 0.186: 0.186w/0.186=26,700/0.186
to get: w=143,548.3871
round to nearest whole number to get your answer: 143,548
you can check your answer by plugging the "part" and "whole" back into the equation. 26,700/143,548.3871=0.186, which was our given percentage. so the answer is correct
