Answer:
First one
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Given
5x - (4x - 1) = 2 ← distribute the parenthesis by - 1
5x - 4x + 1 = 2
x + 1 = 2 ( subtract 1 from both sides )
x = 1
4x+y= x
Move all x term to left side
4x-x+y=0
Subtract 4x from 3x
3x+y=0
Move y term to right side
3x= -y
Divide both sides by 3
X= -y/3
Ok so if it's
4x+y= z solve for x
Move y to right side
4x= -y +z
Now divide both by 4 to get x alone
X= -y/4 + z/4
The circumference of a circle is pi • diamter
3.14 • 50 = 157 meters
Slope (m) equals rise over run
Y-intercept is when x=0
Up (rise) two over (run) one, so 2/1=2 would be your slope.
When x=0, y=2. 2 is your y-intercept.
Plug those into the equation y=mx+b
Y=2x+2. Which is your answer. Glad to help
