Answer:
x = 8/7
Step-by-step explanation:
Step 1: Convert to math
7x - 5 = 3
Step 2: Solve for <em>x</em>
- Add to both sides: 7x = 8
- Divide both sides by 7: x = 8/7
Answer:
Step-by-step explanation:
5. A straight line (view that attached graph)
6. y = x² + (-3) is equivalent to y = x² - 3
0:
y = x² - 3
y = 0² - 3
y = 0 - 3
y = -3
(0, -3)
1:
y = x² - 3
y = 1² - 3
y = 1
y = -2
(1, -2)
2:
y = x² - 3
y = 2² - 3
y = 4 - 3
y = 1
(2, 1)
3:
y = x² - 3
y = 3² - 3
y = 9 - 3
y = 6
(3, 6)
So the answers are: -3, -2, 1, 6
Hope this helps!
Answer:
y is equal to -1
x is equal to 4
Step-by-step explanation:
The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.
Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.
It's A. y=5 because y-lines are horizontal, and x-lines are vet=rtical, and all horizontal and vertical lines are perpendicular (they create a right angle). y=5 line crosses all points that are (x,5) because the 5 in (x,5) is 5 up from the origin and x left or right. y=5 is a horizontal line that is 5 up from the origin.
