Answer:

Raul's claims are not correct

The equation of the graph is $y=\frac{10}{15}x$

Step-by-step explanation:

Part a)

we know that

The fact that the data form a straight line does not imply that it is a proportional relationship. In order for it to be a proportional relationship, in addition to the fact that a straight line must be formed, it must pass through the origin.

In this problem the graph shows a proportional relationship because the data forms a straight line and passes through the origin (0,0)

therefore

The claim that the graph shows a proportional relationship because the data forms a straight line is not correct

Part B)

<u>Find the slope of the straight line</u>

Let

$A(0,0),B(15,10)$

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{10-0}{15-0}$

$m=\frac{10}{15}=0.67\frac{pages}{minute}$

therefore

The claim that he reads 1.5 pages per minute is not correct

Part C)

The equation of the graph is equal to

$y=\frac{10}{15}x$

Your record bicycle pace along a favorite trail is 16 mph. On a recent ride, you traveled the 25 mile route in a time of 90 minu

lara [203]

Average speed=total distance / total time....

s=25/1.5=50/3mph (16 2/3 mph)

So you traveled an average of 2/3 mph greater than your record pace...

The perimeter of a rectangle is dependent on the length of each of its sides. Suppose the base of a rectangle is two more than i

Bezzdna [24]

Perimeter=4h+4

If the base is 2 more than the height, it gives us the equation:
b=h+2

The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.

This can be simplified to be 2h+4+2h or 4h+4
