A line passes through the point (–2, 7) and has a slope of –5.
ICE Princess25 [194]

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!

Find the absolute maximum and absolute minimum values of f on the given interval. f(x) = 16 + 2x − x^2, [0, 5]
RSB [31]

Answer:

<h2>absolute maximum = 16</h2><h2>absolute minimum = 1</h2>

Step-by-step explanation:

To get the absolute maximum and minimum values of the function f(x) = 16 + 2x − x² n the given interval [0,5], we need to get the values of f(x) at the end points. The end points are 0 and 5.

at x = 0;

f(0) =  16 + 2(0) − 0²

f(0) = 16

at the other end point i.e at x = 5;

f(5) =  16 + 2(5) − 5²

f(5) = 16 + 10-25

f(5)= 26-25

f(5) = 1

The absolute minimum value is 1  and  occurs at x  = 5

The absolute maximum value is 16 and  occurs at x  = 0

Pls answer the question in the picture!!! I NEED HELP
pentagon [3]

Answer:

448=h

Step-by-step explanation:

512 - h = 16 x 2²

512 - h = 16 x 4

512 -h = 64

then subtract 512 from both sides

-h = -448

two negatives equal a positive

h=448
