Answer:
440 m
Step-by-step explanation:
We are to assume that Time is measured from the beginning of Amir's drive. So the altitude at the beginning of Amir's drive is the altitude corresponding to Time = 0. That is the point at the left side of the graph where the blue line meets the vertical axis.
The number on the vertical axis at that point is 440, and the label tells us that is meters of altitude. Amir's altitude at the beginning of his drive is 440 meters.
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes
Answer : y - 1 = 1/2 (x-3)
The formula for point slope is y - y1 = m (x - x1)
M is the slope of the line. The nine and three come from the point given. I used the point (3, 1). Hope this helps !

Answer:
r = -1
Step-by-step explanation:
(y2-y1)/(x2-x1)=m
(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5
so plug in...
(4-7)/(4-r)=-3/5
then solve for r which will get that r = -1
numerator: 4-7=-3
denominator: 4-r=5 -> 4-5=0+r -> -1=r
