How to solve and figure it out
Answers
while in point-slope form, y - y1 = m(x - x1), you can definitely see the slope as -5, you can't see the y-intercept as easily. x-intercepts are actually the solutions/zeros of a function, and it was included in the answer choices to confuse you.
you're correct about -5 being a decreasing slope. but to figure out the y-intercept, you need to convert to slope-intercept form.
y - 4 = -5(x + 1) ... distribute the -5
y - 4 = -5x - 5 ... add 4
y = -5x - 1
and in the form of y = mx + b, where m is the slope and b is the y-intercept, you can see that you have a decreasing slope of -5 and a y-intercept of -1. your correct answer is A. choices C and D were thrown in to distract you and make you think that the -5(x + 1) was somehow related to discovering the x-intercept.

Answer:
x = 4
Step-by-step explanation:
Given
- 8 - x = x - 4x, that is
- 8 - x = - 3x ( add 3x to both sides )
- 8 + 2x = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:x=4
Step-by-step explanation:
-8-x=x-4x
-8=-4x+x+x
-8=-2x
divide both sides by -2
x=4

which one has no solutions ?
Answers
5 + 2(3 + 2x) = x + 3(x + 1)
5 + 6 + 4x = x + 3x + 3
11 + 4x = 4x + 3
Subtract 4 from both sides. You are left with an untrue statement:
11 = 3
11 ≠ 3 so therefore your answer is no solution.
First one:
4(x+3)+2x=6(x+2)
We can multiply.
4x+12+2x=6x+12
By looking at this, you can tell it’s equal due to the fact when you add like terms, they will have to same answer.
Second one:
5+2(3+2x)=x+3(x+1)
Let’s multiply.
5+6+4x=x+3x+1
I can already tell this isn’t equal. One has +11 and the other has +1. To make sure, let’s have x=1
5+2(3+2)=1+3(1+1)
5+2(5)=1+3(2)
5+10=1+6
15=7
7 and 15 are not the same number, so the second one doesn’t have any solutions.
