Answer:

B. -1

Step-by-step explanation:

Slope = (y2 - y1)/(x2 - x1)

-5 = (7 - 2)/(-2 - a)

-5(-2 - a) = 5

10 + 5a = 5

5a = -5

a = -1

Answer:

B

Step-by-step explanation:

Let's create an equation in point-slope form, which is: y-y_1=m(x-x_1), where (x_1,y_1) is the point and m is the slope.

Here, our point is (-2, 7) and our slope is m = -5 so plug these in:

y -7=-5*(x-(-2))

y -7=-5*(x+2)

Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:

2 - 7 = -5(a + 2)

-5 = -5(a + 2)

Divide by -5:

1 = a + 2

Subtract 2 from both sides:

a = -1

Thus, the answer is B.

Hope this helps!

The difference of three times a number and 4 is 32. Find the number
Angelina_Jolie [31]

Answer:

3x - 4 = 32

Step-by-step explanation:

We solve for x to find the number (knowing that x is the unknown number).

3x - 4 = 32

3x = 32 + 4

3x = 36

x/3 = 36/3

x = 12

find the surface area of the composite solid round your answer to the nearest tenth and explain your answer
OlgaM077 [116]
I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.

On average, Tony the turtle completes a 15-foot course in 1 minute, and Antonio the turtle completes an 18-foot course in 1 minu
marishachu [46]

Answer:

15 feet.

Step-by-step explanation:

Tony's speed = 15 ft/min.

Antonio's = 18 feet /min.

So in 5 minutes Tony travels 5*15 = 75 feet and Antonio travels 5*18 = 90 feet.

So the answer is 90-75 = 15 feet.
