Answer:
The correct answer is 7.5
Step-by-step explanation:
100x5=500
500÷4=125
125x6=750
750/100=7.5
The answer is 7.5 m
X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)

7*2=14
2 5/7
the answer is B)
good luck
Answer:
m = -1/3
Step-by-step explanation:
y = 3x-4
This is in slope intercept form
y = mx+b m is the slope and b is the y intercept
The slope is 3 and the y intercept is -4
We want the slope of a line that is perpendicular
Perpendicular lines have slopes that multiply to -1
Let m be the slope of the line that is perpendicular
3 * m = -1
Divide each side by 3
3m/3 = -1/3
m = -1/3
Y = $35.25(6) + 40
y = $211.5 + $40= $251.50
the answer is a
