-q-7q=8 whats q equal?

Luba_88 [7]

-q-7q=8
First you need to know that there is an invisible 1 in front of -q. Change it to -q if you need to. You get:
-1q-7q=8
add like terms: -1-7 gives you -8.
-8q=8. Divide by -8 on both sides to find q.
-8/8=-1
8/8=1
Therefore, q=1.

Factor & solve please helppp my brain is mush i don’t remember anything

yanalaym [24]

This equation uses y and x so it cannot be factorised.

Let’s try the equation y^2 - 12y + 36 = 0

Look for two factors of 36 that add to -12.
This would be -6 and -6

(y - 6)(y - 6) = 0
(y - 6) must equal 0
y = 6

Answer:

$\textbf{D.}\quad g(x)=\sqrt{x+6}+4$

Step-by-step explanation:

A lot of math is about matching patterns.

For example, ...

g(x) = f(x -h) +k

means g(x) is the function f(x) translated right by h units and up by k units. This will be true for any expression of f(x).

In this problem, f(x) = √x. We want to translate it left 6 units (h=-6)*, and up 4 units (k=4).

The notation above means that we will replace x with (x-h) = x+6. and we will add k = 4 to the result.

f(x) = √x

g(x) = f(x+6) +4

g(x) = √(x+6) +4 . . . . . . matches choice D

_____

* Left is the opposite of right, so left 6 units is the opposite of right 6 units. h=6 for right 6 units, so h=-6 for left 6 units. Then x-h = x-(-6) = x+6.

Comment on the graph

I find it useful to see a picture with these things. In the attached graphing calculator output, the blue curve is left 6 and up 4 from the red curve. The blue curve is g(x); the red one is f(x).
