Solve for g.
3 =g/-4-5
Step-by-step explanation:
[tex]3 = \frac{g}{ - 4 - 5} [/tex]
Simplify
[tex] - 4 - 5 = - 9 \\ \\ 3 = \frac{g}{ - 9} [/tex]
Cross Multiply
[tex]3 \times - 9 = g \\ - 27 = g \\ g = - 27[/tex]
Answer:
G=-27.
Step-by-step explanation:
G/(-4)-5=3 G(-9)/-4-5=3(-9)=-27.

Create an equation of a line that is parallel to y = 4x – 7
Answer:
There are many..
One would be y = 4x + 7
The trick is the slope is always the same. The only difference is the y-int. You could make one yourself, just use 4x at the beginning.
Please give Brainliest!! Hope this helps!!
9514 1404 393
Answer:
y = 4x
Step-by-step explanation:
A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.
y = mx + b . . . . . line with slope m and y-intercept b
y = 4x -7 . . . . . . line with slope 4 and y-intercept -7
So, the parallel line will be something of the form ...
y = 4x + b
for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.
y = 4x . . . . . parallel line

Step-by-step explanation:
A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form
Solve the equations below by SHOWING YOUR WORK. This includes how you will isolate the variable and keep the equation balanced to get your answer. You must show your work and present your answer for credit. Just an answer will result in no credit. If you are not sure what this means, take a quick look at the videos or recorded lesson. A. B. X - 3.5 = 9.1
Answer:
[tex]X = 12.6[/tex]
Step-by-step explanation:
Given
[tex]X - 3.5 = 9.1[/tex]
Required
Solve for X
Add 3.5 to both sides
[tex]X - 3.5 +3.5 = 9.1 + 3.5[/tex]
[tex]X = 9.1 + 3.5[/tex]
[tex]X = 12.6[/tex]
