777dan777 [17]

Answer:

no solutions

Step-by-step explanation:

3(-n+4)+5n=2n

Distribute

-3n +12 +5n = 2n

2n+12 = 2n

Subtract 2n from each side

12 = 0

This is never true so there are no solutions

An electrician charges 110 after 2 hours of work and 190 for 4 hours of work. Write a linear equation in point-slope form that r
Andrej [43]

Answer:

y = 40x + 30

Step-by-step explanation:

The equation for a linear function is given by:

y = mx + b;

where y and x are variables, m is the slope or rate of change of the function and b is the initial value of y at x = 0 (that is y intercept).

Let y represent the total cost and x represent the number of hours worked.

The electrician charges 110 after 2 hours of work and 190 for 4 hours of work.

Representing in coordinate form as (x, y) we get:

(2, 110) and (4, 190)

The equation of the function can be gotten using the formula:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Therefore:

y-110=\frac{190-110}{4-2}(x-2)\\\\y-110=40(x-2)\\\\y-110=40x-80\\\\y=40x-80+110\\\\y=40x+30
