Answer:

(A - B) - C = { 1 , 4 , 6 , 7 }

Step-by-step explanation:

A = { 1 , 2 , 3 , 4 , 5 }

B = { 4 , 5 , 6 , 7 }

A - B = { 1 , 2, 3 ,6 , 7 }

C = { 2 , 3 , 4 }

(A - B) - C = { 1 , 4 , 6 , 7 }

Slope-intercept from of an equation for the line passes through -1,2 and Parallel to y=2x-3
Dennis_Churaev [7]

The equation of the line in slope - intercept form is y=2 x+4

Explanation:

The line passes through the points (-1,2) and parallel to the line y=2x-3

Since, the line is parallel, the slope is m=2

The y - intercept can be determined by substituting the points (-1,2) and m=2 in the slope - intercept formula, we get,

y=mx+b

2=(2)(-1)+b

2=-2+b

4=b

Thus, the y - intercept is b=4

The equation of the line in slope - intercept form can be determined using the formula y=mx+b

Thus, substituting m=2 and b=4 , we get,

y=2 x+4

Hence, the equation of the line in slope - intercept form is y=2 x+4

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from
dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

p(x) =  - 2 {(x - 9)}^{2}  + 100

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

p(15) =  - 2 {(15 - 9)}^{2}  + 100

We simplify to get:

p(15) =  - 2 {(6)}^{2}  + 100

p(15) =  -72+ 100

p(15) =  28
