Answer:
B -4/5
Step-by-step explanation:
The slope of line D is given by
m = (y2-y1)/(x2-x1)
= (6-1)/ (5-1)
=5/4
We want the slope of the line perpendicular
That would be the negative reciprocal
- (4/5)
Answer:
The x-intercept is 8/7.
Step-by-step explanation:
There is only one x-intercept because the equation is linear. And you don't need the quadratic formula to find the x-intercepts at all. Hope this helps!!
The answer is c
Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25
x = 375 and y = 6300. Option C.
Step-by-step explanation:
From the given data we need to find the value of x and y.
First, we will find out the ratio of area and the force.
= 
So,

or, x =
= 375
Again,

or, y = 420×15 = 6300
Hence,
x = 375 and y = 6300.
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one
m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one
