Answer:
m=13/7
Step-by-step explanation:
the equation for slope (m) is (y2-y1)/(x2-x1)
the given points are (0,5) and (-7,-8)
we can label them:
x1=0
y1=5
x2=-7
y2=-8
now substitute into the equation
m=(-8-5)/(-7-0)
m=-13/-7
m=13/7
the slope is 13/7
hope this helps!
Hi. The terms of the standard charge and insurance charge equations are a little garbled, but it is possible to think that these are the right equations:
Standard charge, S = 15.75 + 0.40M, where 15.75 is the initial fee and 0.40 is the charge for each mile driven.
Insurance charge, I = 4.90 + 0.25M, where 4.90 also represents an initial fee and 0,25 a charge for each mile driven.
Then, the total cos, C = S + I =>
C = (15.75 + 0.40M) + (4.90 + 0.25M) which you can rearrange to show the like terms one next to each other =>
C = (15.75 + 4.90) + (0.40M + 0.25M), now add up the like terms=>
C = 20.65 + 0.65M which is the equation is the most simplified form
Answer: C = 20.65 + 0.65M
Answer:
Option B, $2020.00
Step-by-step explanation:
Volume of the pool,
12×5×14.5+4×5×7
= 1010 ft³
each cubit foot costs $2, so 1010 ft³ will cost,
1010×$2
= $2020
Answer:
Cathy was driving at a speed of 67 miles per hour.
Step-by-step explanation:
Fined $15 for each mile per hour over the speed limit. Cathy was given a ticket for $105.
We solve this using a rule of three.
1 mile - $15
x miles - $105
Applying cross multiplication:
15x = 105
x = 105/5 = 7.
Cathy was 7 miles above the speed limit.
How fast was Cathy driving?
7 miles above the speed limit of 60 miles per hour, so 60 + 7 = 67 miles per hour.
Cathy was driving at a speed of 67 miles per hour.
