Answer:

k = -9

Step-by-step explanation:

subtract 2k from both sides

_5k+8= -37

subtract 8

_5k = -45

divide by 5

_k = -9

Subtract 2k on both sides, to get 5 k +8= -37. Then subtract 8 on both sides to get 5k= -45 Then divide by 5 on both sides to get k= -9.

Answer:

Step-by-step explanation

In the form ax^2+bx+c

a x c should equal two factors of b

However, in this equation

1 x 19 has no factors that = 10

so you must use the Quadratic Formula which is,

x = $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

so the answer should be

x = $\frac{-10+-\sqrt{10^2-4(1)(19)} }{2(1)}$

x = $\frac{-10+-\sqrt{24} }{2}$

x = $\frac{-10+2\sqrt{6} }{2}$ and x = $\frac{-10-2\sqrt{6} }{2}$

r-ruslan [8.4K]

Answer:

B = (-6, 6)

Step-by-step explanation:

If M is the midpoint of AB, then ...

B = 2M - A

B = 2(-1, 4) -(4, 2) = (-2-4, 8-2)

B = (-6, 6)

Easy!!!

aksik [14]

Step-by-step explanation:

f(g(10))

This is called a composite function. It's when you plug one function into another.

First, find g(10):

g(x) = √(x-9)

g(10) = √(10-9)

g(10) = √1

g(10) = 1

Then plug that into f(x):

f(x) = -9x - 9

f(g(10)) = -9 g(10) - 9

f(g(10)) = -9 (1) - 9

f(g(10)) = -9 - 9

f(g(10)) = -18
