Answer:
42.9%
Step-by-step explanation:
-42.857142857142854 is the exact number. Rounded to 42.9% thus b: is the correct answer.
Formula:
[(120 - 210) / 210] × 100% = -0.42857142857142855 × 100% = -42.857142857142854%
Addition and multiplication
Answer:
slope is -1
Step-by-step explanation:
y=mx+b
(m=slope)
(b= y-intercept)
y-intercept= -2
slope and x is -x.
there is always a 1 in front of the x.
so...
-1x = mx take out x.
m= -1 or slope = -1
Answer:
One way is to:
First, multiply 2 by the term inside the parenthesis.
Second, add eleven on both sides.
Third, divide using 4x on both sides.
This will give you your first method.
Now try to get the second on your own.
Step-by-step explanation:
Answer:
y = 3x -2
Step-by-step explanation:
If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.
You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.
y = m*x + b
7 = 3*3 + b
7 = 9 + b
-2 = b
y = 3x -2
I Hope This Helps :D
