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

A=20
Answer:
x = 7
Step-by-step explanation:
Lets do the brackets first,
6 × 2x = 12
6 × -11 = -66
------
Calculate the x constant:
12x - 3x = 9x
-------
Then the ones with no x:
-66 + 15 = -51
51 + 12 = 63
-------
Lastly, divide
63 ÷ 9 = 7

Answer:
3.9
Step-by-step explanation:
The retained earnings for the year is $205,000
The firm paid out $185,000 in cash dividend
It has total equity of$4.90 million
100,000 common shares are outstanding
Therefore the earnings per share van be calculated as follows
= 205,000+185,000/100,000
= 390,000/100,000
= 3.9
Hence the earnings per share is $3.9
