Step-by-step explanation:
Given that,
DE = 8x - 13
EF = 5x + 17
DF = x + 21
Also,
DE = EF
which means that,
8x - 13 = 5x + 17
8x - 5x = 17 + 13
3x = 30
x = 30/3
x = 10
Now,
DE = 8x - 13 = 8×10 - 13 = 80 - 13 = 67cm
EF = 5x + 17 = 5×10 + 17 = 50 + 17 = 67cm
DF = x + 21 = 10 + 21 = 31cm
Answer:
y = 7x + 12
Step-by-step explanation:
Slope (m) = 7
Line is passing through the point (0, 12)
y-intercept (b) = 12
Equation of line in slope-intercept form is given as:

6 and 3000 is the answer for ur question would be 3000
Answer:
The equation c = 0.02p+149 represents micks commission.
Step-by-step explanation:
Given that:
Amount earned by Nick on sale of each boat = $149
Commission earned = 2% of the purchase price
p represent the purchase price
Commission earned = 
Commission earned = 0.02*p
Commission earned = 0.02p
Total commission = c = 0.02p + 149
Hence,
The equation c = 0.02p+149 represents micks commission.
