Answer:
y = 3
y = 5
(last answer choice)
Step-by-step explanation:
A system of equation is given in "x" and "y".
For it to have a solution, there should be a value for x and a value for "y".
There needs to be 2 values, one for x and another for y.
It doesn't matter if the values of x and y are same, but there needs to be one value of x and one value of y (if linear equations).
First one has a value of x = 5 and y = 3, so there are 2 values, one for x and another for y, distinct values. So it's okay.
The second one has 2 values for x and y, respectively. THey are same, doesn't matter. So, this one is okay as well.
The last one has NO VALUE for x and has 2 values for y. So, this one doesn't have a proper solution.
So, the last one of the choices shown has NO SOLUTION.
A x b = -15
-3 x 5 = -15 or it can be -5 x 3= -15
how i got that is you ask what 2 numbers go into -15
3 and a -5 or it can be 5 and a -3
Answer: 45 miles in one hour
Step-by-step explanation:
(1,4) this is because the flip over y axis does not touch the y value but gives the opposite of the x value
