The answer is D, here’s why:
You know the slope-intercept form is y=mx+b
mx being the slope and b being the y-intercept.
y=-4/7x + 9 is already in that form.
A is not the answer because the y is supposed to be by itself.
B is not the answer because again, the y is not by itself.
C is not the answer because the y is also not by itself.
In the slope-intercept form, the y must be by itself and the slope (mx) and the y-intercept must be on the other side.
Hope this helps.
Answer:
To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.
Step-by-step explanation:
As an example, in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.
Answer:
2/6 more.
Step-by-step explanation:
You need to find a common denominator. In this case it was 6.
Answer:
x^7+x^6+x^5-x^4-x^3-x^2-x+1
Step-by-step explanation:
90=l+l+w+w
90=28+28+w+w
90=56+2w
34=2w
17=w
The width of the playground is 17.
