Let x be the number of hours that Chaya studies for a test and let y be the number of points she receives on the test. For one test, Chaya studied for 5 hours and received 14 points. Select all the equations that could describe Chaya’s grades and her study time.

A and C I think

Step-by-step explanation:

2.8 x 5 = 14, and 5 + 9 = 14.

the answer is y=2.8x and y=x+9

Step-by-step explanation:

hope this helped

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

1/4 because there is 4 grades.
