An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
Answer:
q=17
Step-by-step explanation:
5q-10=75
add 10 to both sides to cancel out -10 on the left side
5q-10+10=75+10
5q=85
divide both sides by 5 to get rid of the 5 in 5q
5q/5=85/5
resulting in:
q=17
Answer:
g(x) = (f-x)
Step-by-step explanation:
It's relection across the y axis
==> g(x) = (f-x)
1/1 because if you’ve already take one or orange out of the box you would only have one left to select two from the same box. you started with 2/2 and took one out put 1/1.
