Answer:IS D PLEASE MARK ME
Step-by-step explanation:
The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).
y = 10x + 20
We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.
y = 10(50) + 20 = $ 520
Thus, the charity can earn $520 if 50 cars come in for a wash.
Answer:
<u><em>The area of the irregular figure is 140 sq. ft.</em></u>
Step-by-step explanation:
<em>Triangle:
</em>
<em>
</em>
<em>16-12=4
</em>
<em>
</em>
<em>6 x 4 = 24
</em>
<em>
</em>
<em>24 x 0.5 = 12
</em>
<em>
</em>
<em>Triangle = 12
</em>
<em>
</em>
<em>Rectangle:
</em>
<em>
</em>
<em>16 x 8
</em>
<em>
</em>
<em>= 128
</em>
<em>
</em>
<em>Rectangle = 128
</em>
<em>
</em>
<em>Total figure:
</em>
<em>
</em>
<em>128+12
</em>
<em>
</em>
<em>= 140
</em>

The x intercept of the line is at x = 10.
The x intercept is always the value of x when all other values are equal to 0. So in this case, we put 0 in for t and then solve.
-2x + 5t = -20
-2x + 5(0) = -20
-2x = -20
x = 10
