You can use a matrix equation to discover that the motel clerk has 45 $1 bills and 12 $10 bills.
Answer:
Step-by-step explanation:
y = 3*x + 4
y = 3*x - 7
Each one of the above equations is the equation for a straight line.
The solution for such a system is the point P ( x₀ , y₀ ) which coordinates belong to both straight lines. According to this, there is only one solution for that system ( only one point of intersection). The intersection of a pair of straight lines either can occur or not depending on the slope of the lines, if they have the same slope they are parallel, then they did not touch each other ever. How can m, be identified in the straight line equation??, just by looking at the coefficient of x.
The two equations have slope 3 they are parallel then there is not a solution ( there is not a common point to both equations)
Hey there! :D
So, we can just divide all the numbers to figure it out.
31/9= 3.44444444
32/9=3.5555556
33/9= 3.66666777
34/9= 3.777778
The closest number to 3.4 is 31/9. "A" is the correct answer.
I hope this helps!

Save 25% on any computer is the better deal. Then the correct option is A.
<h3>What is the percentage?</h3>
The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A) Save 25% on any computer. Then the better deal will be
→ 579 × 0.25 = $ 144.75
B) Save $150 on any computer. Then the better deal will be
→ $ 150
C) Save $75 plus 5% off on any computer. Then the better deal will be
→ 579 × 0.05 + 75 = $ 103.95
D) Save $50 plus 10% off on any computer. Then the better deal will be
→ 579 × 0.10 + 50 = $ 107.9
