Answer:
The system of equations is inconsistent because there's no solution.
Step-by-step explanation:
7y = 11.2x + 28 is a multiple of y = 1.6x + 4. Thus we have the same equation at the end.
Multiply y = 1.6x + 4 by 7.
7y = 11.2x + 28... Equation 1
7y = 11.2x + 28... Equation 2
Subtract equation 2 from 1.
7y - 7y = 11.2x - 11.2x + 28 - 28
0 = 0 + 0. There's no solution for x and y.
In order to determine whether a quadrilateral on the coordinate plane is a parallelogram, you must use <span>the slope formulas, the distance formula and the midpoint formula. By using the distance formula, you will find the length of each sides to see if the opposite side is congruent.</span>
Bryan has to take 8 classes for both Pro's to be the same price.
Step-by-step explanation:
Given,
Monthly charges of Pro at Windy = $20.00
Charges per lesson = $10.00
Let,
x be the number of lessons
W(x) = 10x +20
Monthly charges of Sunny Sands = $100.00
They offer unlimited classes.
S(x) = 100
For the price to be same;
W(x) = S(x)
Dividing both sides by 10
Bryan has to take 8 classes for both Pro's to be the same price.
