I am having a hard time with an Algebra question on systems of equations and graphing: y= 5x-8
y= -5x+2

The answer choices are:
A. The solution is ____( fill in whatever the solution is).
B. There is infinitely many solutions.
C. There is no solution.
I also have to graph it so what what would I graph if need be?
Thanks so much!!!

Answers

Answer 1

Answer: 1)First you substitute what we already know y equals
-5x+2=5x-8
2) if you solve that you get that x=1
3) put x back in one of the original equations
y=5(1)-8
4) then you get y as -2

A) the solution is x=1 y=-2

You would graph x and y and a coordinate point (1,-2)

What is the value of x?

Answers

As they are vertical angles, their magnitude will be equal.
8x+8 = 2x+38
8x-2x = 38-8
6x = 30
x = 5

So, Your Final Answer would be 5

5x-8 (4x-7)=2 solve for x

Answers

5x - 8(4x - 7) = 2

First, expand your problem. / Your problem should look like: $5x - 32x + 56 = 2$
Second, simplify 5x - 32x + 56. / Your problem should look like: $-27x + 56 = 2$
Third, subtract 56 from both sides. / Your problem should look like: $-27x = 2 - 56$
Fourth, subtract 2 - 56 to get -54. / Your problem should look like: $-27x = -54$
Fifth, divide both sides by -27. / Your problem should look like: $x = (-54)/(-27)$
Sixth, simplify the fraction to $- (54)/(27)$ / Your problem should look like: $x = (54)/(27)$
Seventh, simplify. / Your problem should look like: $x = 2$

Answer: x = 2

True or False: Only like terms can be combined. A True B False

Answer:

True

Step-by-step explanation:

Like terms like 4x-3x the x term. is a like term

6-4x can be subtracted because they aren't the same.

$y=4x-2\n \nreverse \ the \ x \ and \ y \ to \ get \n \n x=4y-2 \n \n solve \ for \ the \ new \ y \ to \ get \n \n4y =x+2 \ \ / :4 \n \ny=(x)/(4) + (2)/(4) \n \ny=(1)/(4)x + (1)/(2)\n \n The \ answer \ is : \n \n y=(1)/(4)x + (1)/(2)$

y=4x-2

change:

x = 4y - 2
4y = x + 2
y = x/4 + 1/2 <--- inverse
