Answer:
y=2x+24
Step-by-step explanation:
Hi there!
We are given that a line has a slope of 2 and passes through (-7, 10)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the y-intercept
As we are already given the slope, we can immediately substitute it in for m
So replace m with 2 in y=mx+b
y=2x + b
Now we need to find b
As the equation passes through the point (-7, 10), we can use its values to help us find the value of b
Substitute -7 as x and 10 as y
10 = 2(-7) + b
Multiply
10 = -14 + b
Add 14 to both sides
24 = b
Substitute 24 as b into the equation
y = 2x + 24
Hope this helps!

Answer:
D. 200-2/3x=2/5
Step-by-step explanation:
You can tell that one side of the equation is going to have only 2/5 because the problem said there was 2/5 of a ton left. You can also figure out that the equation should say 200-2/3x because the problem said that the conveyor belt removes 2/3 of a ton per minute. So, the equation should be...
200-2/3x=2/5, which is D.
Hope this helps c:
According to the first statistic, then:
.8:100::1.5:x
So:
.8x=150
x=150/.8=187.5
It follows that the skydiver would fall 187.5 ft in 1.5 seconds

Answer:
Hm im not sure but hold on, i think i found it. 1 and 76
Step-by-step explanation:
To find r, you need to isolate it. pi*r^2*60=18,840. divide 18,840 by 60, then pi, it comes out at 100. Now find the square root to get 10
r=10
