Answer:
its the first one
Step-by-step explanation:
Answer: 31.25%
Step-by-step explanation: To answer the question <em>what percent of 80 is 25</em>, we translate the question into an equation.
So we have "what percent" that's x, "of 80" means times 80, "is 25" = 25.
Now to solve for <em>x</em>, since <em>x</em> is being multiplied by 80, we need to divide by 80 on both sides of the equation. On the left side of the equation the 80's cancel and we have <em>x</em> and on the right side of the equation, we have 25 ÷ 80 which gives us 0<em>.</em>3125. Now, remember that we want to right our answer as a percent so to write 0.3125 as a percent, we move the decimal point 2 places to the right and we get 31.25%.
Therefore, 31.25% of 80 is 25.
Pareallell lines have same slope
y=mx+b, m=slope
y=3x-8 so we need
y=3x+b
find b
so given (4,-5)
we can subsitute the point
(x,y)
(4,-5)
x=4 then y=-5
so
-5=3(4)+b
-5=12+b
-17=b
y=3x-17 is equation
D is answer
Answer:
y =
x - 2
Step-by-step explanation:
slope intercept form
y = mx + b
m = rise / run = -5 / 6
b = -2
y =
x - 2
