Answer:
Step-by-step explanation:
Let
x -----> the number of hours
y ----> the total cost to rent a bike in dollars
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or the unit rate of the linear equation
b is the y-intercept or the initial value
In this problem we have
The unit rate or slope is equal to
The y-intercept (value of y when the value of x is equal to zero) is equal to
----> (fee charge)
substitute the values
If u don't understand lemme know
Answer:
a = 22
b = 7
Step-by-step explanation:
Let the two numbers be represented as a and b.
a + b = 29
a - b = 15
Using elimination method
Add both equations
2a = 44
Divide both sides by 2 to get a
2a/2 = 44/2
a = 22
Now substitute a = 22 in any of the equations to get b .
Using the first equation, we have
a + b = 29
22 + b = 29
Subtract 22 from both sides of the equation
22 - 22 + b = 29 - 22
b = 7
Therefore the two numbers are 22 and 7
Answer:
C) 75 + 50x = 25 + 70x
Step-by-step explanation:
ABC Tech:
$50 an hour. So,for x hours= 50 * x = 50x
Service charge = 75 + 50x
Tech Squad:
$70 an hour. So,for x hours= 70 * x = 70x
Service charge = 25 + 70x
C) 75 + 50x = 25 + 70x
50x - 70x = 25 - 75
-20x = -50
x = -50/-20
x =5/2 = 2
