Answer:
8
Step-by-step explanation:
We can start by making an equation. The number we're solving for will be represented by x.
4x-5=27
Add 5 to both sides.
4x=32
Divide both sides by 4.
x=8
There you go! The number you're looking for is 8.

Answer:
The answer is: y - 0 = -1/2(x - 2)
Step-by-step explanation:
Given - an equation in standard form:
-6x + 3y = 6
Solve for y:
Add 6x to both sides:
3y = 6 + 6x
y = 2 + 2x
y = 2x + 2, so the slope is 2.
The perpendicular slope is the negative inverse of 2, which is -1/2.
Point slope form is:
y - y1 = m(x - x1)
Substitute in the numbers from the point (2,0) and the slope -1/2:
y - 0 = -1/2(x - 2)
Taking it to y intercept form:
y = -1/2x + 1
Answer:
5k²+8k+3
Step-by-step explanation:
5k²+5k+3k+3
5k²+8k+3
Answer:
x = 3, y = 1
Step-by-step explanation:
2y = 2x - 4, so y = x - 2. Substituting this into the bottom equation and solving for x:
x - 2 + 3x = 10
4x - 2 = 10
4x = 12, so x = 3 and y = 1.
