Answer:
z = (17+4w)/(w-m)
Step-by-step explanation:
w • (-4+ z) = mz + 17
Distribute
-4w +wz = mz+17
Subtract mz from each side
-4w +wz - mz = mz+17-mz
-4w +wz-mz = 17
Add 4w to each side
-4w +4w+wz-mz = 17+4w
wz-mz = 17+4w
Factor out z
z(w-m) = 17+4w
Divide by (w-m)
z(w-m)/(w-m) = (17+4w)/(w-m)
z = (17+4w)/(w-m)
Answer:
They spent $600 on costumes.
Step-by-step explanation:
10% = $800 ÷ 10 = $80
20% = $80 x 2 = $160
50% = $800 ÷ 2 = $400
5% = $80 ÷ 2 = $40
400 + 160 + 40 = $600

Answer:
y < -1/2
Step-by-step explanation:
When dividing fractions, you use Keep Change Flip.
= 4/3 x -3/8
=-1/2
y < -1/2
Step-by-step explanation:
As
- The graph of the function passes through the point (2,1), and
- y increases by 4 when x increases by 1.
so
x y
2 1
3 5
4 9
5 13
6 17
and so on
From the table:




As the slope-intercept form of the line is

putting m=4 and any point, let say (2, 1) to find y-intercept 'b'.




So putting
and
in the slope-intercept form of the line


Therefore, the equation for the linear function will be:

You buy 6 shirts. So $77 minus $5=$72
Then you divide $72 by $12 and you get 6 shirts
