Answer:
b = 40
Step-by-step explanation:
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.
This situation can be described by an equation of the form y=mx+b , where
x = the time in hours
y = the cost in dollars.
What is the value of b in this equation?
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair
Writing the above in an equation =
y = $70 × x + $40
y = 70x + 40
Therefore, the value of b in the expression = 40
Answer: x=12
Step-by-step explanation:
we know that sum of a triangle is 180 degrees
one angle is 90 degree
the sum will be 90+(2x+1)+(5x+5)=180
substract 90 from both sides
2x+1+5x+5=180-90
7x+6=90
7x=90-6
divide by 7
x=12
Answer:
x=6
Step-by-step explanation:
7x =42
7 7
x=6
Divide 7 on both sides
Answer:
8+10+8+10=36+ 2 x 3.14 x radium/2
Step-by-step explanation:
<span>Y = 360,000 - 1500 X
X-intercepts; Y = 0
1500 X = 360,000
X = 240
Y-intercepts; X = 0
Y = 360,000
The Y-intercepts corresponds to the value of the property 0 months after purchase.
The X -intercepts corresponds to the number of months that have passed before the value is 0.
The property is fully depreciated after 240 months or 20 years</span>
