Equation 1: y = -2x + 1
Equation 2: y = 2x - 3
Since both equations already have y isolated, we are able to simply set the right side of both equations equal to each other. Since we know that the value of y must be the same, we can do this.
-2x + 1 = 2x - 3
1 = 4x - 3
4 = 4x
x = 1
Then, we need to plug our value of x back into either of the original two equations and solve for y. I will be plugging x back into equation 2 above.
y = 2x - 3
y = 2(1) - 3
y = 2 - 3
y = -1
Hope this helps!! :)
Answer:
It's the second option
Step-by-step explanation:
Graph for -(x+3)(x+1)
Answer:
C; None of the above.
Step-by-step explanation:
Pretend x=1, y=0, and z=2.
You have to match an answer to 1+0-2 (equals to -1).
The first equation would be 2+0+1. When you add them all together you get 3, and that isn't equivalent to -1, so therefore this one is not the answer.
The second equation becomes 1+2+0, and when you solve for the answer, you see that the answer is also 3, and so we can conclude that neither A or B matches with the equation above, so the answer is C, None of the above.
Answer:
No solution.
Step-by-step explanation:
Step 1: Write inequality
3(x - 2) + 1 ≥ x + 2(x + 2)
Step 2: Solve for <em>x</em>
- Distribute: 3x - 6 + 1 ≥ x + 2x + 4
- Combine like terms: 3x - 5 ≥ 3x + 4
- Add 5 to both sides: 3x ≥ 3x + 9
- Subtract 3x on both sides: 0 ≥ 9
Here we see that the statement is false. Therefore, you cannot solve for the inequality.
