Answer:
Step-by-step explanation:
y + 2 = 4(x - 1)
y + 2 = 4x - 4
y = 4x - 4 - 2
y = 4x - 6
Comparing with y = mx + c
Where m is the slope and c the intercept
Slope m = 4 and c = -6
Answer:
171
Step-by-step explanation:
multiply 38% by 450
Since you have an equation equal to both x and y, you can either substitute the equation equal to x for x or the equation equal to y for y.
x=y-1
y=4-2x
I would substitute the y in using 4-2x
x=(4-2x)-1
x=3-2x
3x=3
x=1
Then plug in x and solve for y
1=y-1
2=y
It there are 100 centimeters in 1 meter, then there are 700 centimeters in 7 meters. :)
