Answer:

Rate of change = 5

Step-by-step explanation:

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the rate of change of the line is

$m=\frac{y_2-y_1}{x_2-x_1}$

From the given graph it is clear that the line passes through the points (1,-1) and (2,4).

Using the above formula, the slope of the line is

$m=\frac{4-(-1)}{2-1}$

$m=\frac{4+1}{1}$

$m=\frac{5}{1}$

$m=5$

Therefore, the rate of change of given line is 5.

Tyler does squats and pushups. He wants to increase the number of each type of exercise by 20% by the end of the month. He curre

Semenov [28]

Answer:

Tyler currently does 40 squats

Step-by-step explanation:

Tyler does squats and pushups.

<u>Currently:</u>

Number of pushups = 25

Number of squats = x

Total number = 25 + x

<u>After increase:</u>

Number of pishups $=25\cdot (1+0.2)=1.2\cdot 25=30$

Number of squats $=x\cdot (1+0.2)=1.2x$

Total number $=30+1.2x$

If Tyler meets his goal, he will do a total of 13 more squats and pushups than he does now, thus

$(30+1.2x)-(25+x)=13\\ \\30+1.2x-25-x=13\\ \\1.2x-x=13-30+25\\ \\0.2x=8\\ \\2x=80\\ \\x=40$

Work out the value of x

Korvikt [17]

Answer:

117 degrees

Step-by-step explanation:

So we already know that one angle is 38 degrees, so we have that one. The angle, 101 is exterior, and we have to subtract 180 from that to get the interior angle. We get a difference of 79. Since the sum of a triangle's interior angles are 180, we have to add 38+79 to get 117. Then, we have to subtract it from 180 to get the value of the interior angle as 63 degrees. Because x is on the outside, we have to again subtract 63 from 180 to get the missing value of x as 117.

Find the sale price

Nimfa-mama [501]

24.5x.18=4.41

$4.41 is how much you save with the discount. You subtract this amount from the regular price.

24.5-4.41=20.09

The sale price of the item should be $20.09
