Answer:
1/15
Step-by-step explanation:
-1/3 -(-3/5)
-1/3 + 3/5
(-1 × 5) / (3 × 5) + (3 × 3) / (5 × 3)
-5 / 15 + 6 / 15 = 1/15
The Answer Is 1/21 This Is The Answer:
Using a linear function, it is found that Company D would have given you the best deal for 7 hours of moving.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, we consider:
- The flat fee as the y-intercept.
- The hourly rate as the slope.
Hence the costs for x hours of moving from each company are given as follows:
For 7 hours, the costs are given as follows:
- A(7) = 50 + 25 x 7 = $225.
- B(7) = 40 + 30 x 7 = $250.
- C(7) = 60 + 20 x 7 = $200.
- D(7) = 150 + 5 x 7 = $185.
Due to the lower cost, Company D would have given you the best deal for 7 hours of moving.

Since we can find a solution for this system of equations we can affirm this is an independent system with solution equal to (x,y) = (3,-1)
* If we graph a dependent system in the slope - intercept form, we can see that the graphs of each one are identical to each (beacuse we are representing the same line).
*An inconsistent system occurs when the equations have the same slope, but different values of intersection with the Y axis.
Answer:
Isosceles and acute
Step-by-step explanation:
=> This triangle have two sides congruent so it's isosceles.
=> This triangle has all of it's angles less than 90 so it is an acute triangle.
