Which equation has a graph perpendicular to the graph 7x=14y-8

Mathematics
1 answer:
IrinaVladis [17]3 years ago

<span>Slope-intercept form is y = mx + b
m is the slope 
b is the y-intercept 

7x = 14y - 8

7x + 8 = 14y {added 8 to each side}
(1/2)x + (8/14) = y
slope is 1/2 

A line perpendicular would have a slope of -2 {the negative reciprocal of 1/2} 

#1 y = -2x - 7 {it is the only one with a slope of -2}</span>

10 people who build at the same rate can frame a house in 6 days. What fractional part of a house can 4 people frame a house in
Alina [70]

10 people who build at the same rate can frame a house in 6 days. That means it will take one person 10\times6=60 days to finish the house.

Which means that it will take 4 people \frac{60}{4}=15 days to finish the house.

So, the fractional part of the house 4 people can frame in 3 days will be \frac{3}{15}=\frac{1}{5}

Thus, Option D is the correct answer.
