Answer:
0.0654 cm^3
Step-by-step explanation:
Answer:
1. x = 8
2.
Step-by-step explanation:
1. Solve the rational equation
First, cross multiply:
Now, use distributive property:
Separate terms with x and without x into different sides of equation:
Simplify:
Divide by -4:
2. The rational function
This rational function is undefined for all values of x, for which the denominator is equal to 0. Find these values:
This means that the line is a vertical asymptote for the rational function f(x).
Answer:
Electrician's fee: $50.
Charges per hour: $35
Step-by-step explanation:
Let x represent number of hours and y represent amount charged.
We have been given that an electrician charges $120 after 2 hours of work and $190 after 4 hours of work.
We can represent this information with two points as (2,120) and (4,190).
First of all, we will find slope using these points.
Now, we will slope-intercept form of equation to get our required equation as:
Substitute coordinates of point (2,120) to find the y-intercept.
Therefore, our required function would be .
The electrician's fee would be $50 as it the initial amount or y-intercept.
The electrician charges $35 per hour as the slope of the line is 35.
You can find a unit rate
by turning the ratio into a fraction and divide
Like $4 in 2 months and thats 4/2
Its $2 every month
Idk if this helps :P
