5+x=32
x= the number of apples Sarah had before
5+x=32
subtract 5 from both sides
x=27
40000+1000x=60000
-40000. -40000
1000x=20000
x=20
Slope Formula: y2 - y1 / x2 - x1
(m and slope represent the same quantity)
m = 1 - - 5 / -4 - 0
m = 1 + 5 / -4
m = 6 / -4
m = -3/2
Now that we know the slope, we can plug the slope and one of our points into slope-intercept form (y = mx + b) and solve for b. I will be using the point (-4,1).
y = -3/2x + b
1 = -3/2(-4) + b
1 = 6 + b
b = -5
In point form, the y-intercept is (0, -5).
Therefore, to get the equation all we need to do is plug in our slope and b-value to slope-intercept form.
Equation: y = -3/2 x - 5
To check the point (-6, -14) we plug it into our equation and see if the two sides are equal.
-14 = -3/2(-6) - 5
-14 = 9 - 5
-14 = 4
-14 does not equal 4, therefore the point is NOT on the line.
Hope this helps!
You're answer is: 0.7%
Explanation:
To get the answer, simply multiply 100 by 7/1000 which would give you 0.007. Then once you get 0.007 you'll need to multiply again by 100. Which would give you 0.7%
7/1000×100=0.007
0.007×100=0.7%
That being said, 0.7% is the correct answer.
