Step-by-step explanation:
Which values for A and B will create infinitely many solutions for this system of equations?
Answer:
A = -6; B = 15
Step-by-step explanation:
4x-Ay=15
-4x+6y=B
This is your system of equations. For it to have infinitely many solutions, the lines have to be the same. This means that if you multiply one equation by a constant, you should be able to get the other one.
With this system, you have 4x in one equation and -4x in the other. You can use this to figure out the constant. Because -4 is, well negative four, you know that the second equation is the opposite of the first; everything is multiplied by -1.
That means A = -6 and 15 = -B (The other coefficients and constants of the equations also have to be opposites.), and you can solve for B now. Divide by -1 to get B=15.
Hope I could help!

Step-by-step explanation:
A contractor purchases 5 dozen pairs of padded work gloves for $67.80. She incorrectly calculates the unit price as $13.56 per pair for the expense report. What is the correct unit price? What is the error?
Answer:
I think the answer would be $1.13 per pair.
Step-by-step explanation:
It states that there were 5 dozen gloves, a dozen equals 12, or in this case 12 pairs. 5 dozen means there would be 5×12=60 or 60 pairs. 67.80÷60(pairs)=1.13 dollars PER pair.
The error is that she divided with the 5 dozens, instead of individual pairs.
