Answer:
One Way: 79 + 62H + 15H = X
Second Way: 79 + ((62 + 15) x H) = X
Step-by-step explanation:
Given that a plumber charges a customer a one-time service fee of $ 79, $ 62 per hour for labor, and a surcharge of $ 15 per hour due to the call being an emergency, to write an expression to represent the total charges for the plumber in two different ways, with H representing the number of hours the job takes, the following equations should be formulated:
79 + 62H + 15H = X
So, for example, if the job had lasted 2 hours, the equation would apply as follows:
79 + 62x2 + 15x2 = X
79 + 124 + 30 = X
233 = X
79 + ((62 + 15) x H) = X
In the case, if the work had lasted 1 hour, the equation would apply as follows:
79 + (62 + 15) x 1) = X
79 + 77 x 1 = X
79 + 77 = X
156 = X

Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (8, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = - x + 2 ← equation of perpendicular line
