Answer:
-8/3
Step-by-step explanation:
8x + 3y = - 9
Let's make y the subject of the formula.
y = - 9/3 - 8x/3
Rearrange
y = - 8x/3 - 3
The slope is the coefficient of x which is - 8/3

A plumber charges his customers $25.70 per hour, h, plus a $54.50 service fee.On Tuesday,he earns $118.75 for fixing Mrs.Goodwill's sink. How long does it take the plumber to fix Mrs.Goodwill's sink
Answer:
2.5 hours
Step-by-step explanation:
Given that :
Charge per hour = 25.70
Service fee = $54.50
If total earning = 118.75 ; how many hours did it take to fix the sink?
Let number of hours = x
Total earning = service fee + (charge per hour * number of hours)
118.75 = $54.50 + (25.70x)
118.75 - 54.50 = 25.70x
64.25 = 25.70x
x = 64.25 / 25.70
x = 2.5
Hence, it took 2.5 hours to fix the sink

1. An interior design company needs materials for a new job. They need to purchase four doors. Each door costs $185.95. They also need to buy 10 windows that cost $148.56 each. What is the total price of the doors and windows that need to be purchased? Answer:
Answer:
[tex]\$2229.4[/tex]
Step-by-step explanation:
Cost of 1 door = [tex]\$185.95[/tex]
Total number of doors = 4
Cost of 4 doors = [tex]\$185.95\times 4=\$743.8[/tex]
Cost of 1 window = [tex]\$148.56[/tex]
Total number of windows = 10
Cost of 10 windows = [tex]\$148.56\times 10=\$1485.6[/tex]
Total price of the doors and windows that needs to be purchased is [tex]\$743.8+\$1485.6=\$2229.4[/tex].

B −318x+6310
C 378x−1910
D −378x+1910
Answer:
i have the samething omg
Step-by-step explanation:
The difference of the given expressions is 274x - 4325.
The given expressions are 38x+215 and 312x−4110.
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, 38x+215 is subtracted from 312x−4110
That is, 312x−4110 - (38x+215)
= 312x-38x-4110-215
= 274x - 4325
Therefore, the difference of the given expressions is 274x - 4325.

Explanation:
The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.
All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.
Set 2x+32 equal to 60 and solve for x
2x+32 = 60
2x = 60-32
2x = 28
x = 28/2
x = 14
As a check,
2x+32 = 2*14+32 = 28+32 = 60
which helps confirm the answer.
