I never do this but I just don’t understand! Does anyone have the answers to the International Connections Academy Systems Of Equations And Inequalities Unit Test in algebra 1? The first question is
Which graph represents the solution to the given problem
Y=-x+5
Y= 1/4x+10
Thank you
That was all wrong I got 5/15
I'm assuming 1/4x means (1/4)x or x/4.
Y = -x + 5.
Y = x/4 + 10.
In Eq2, replace Y with -x + 5:
-x + 5 = x/4 + 10
Multiply both sides by 4 and solve for x:
-4x + 20 = x + 40.
-5x = 20,
X = -4.
In Eq1, replace x with -4 and solve for Y:
Y = -(-4) + 5 = 9.
Solution: (x, y) = (-4, 9).
Locate X(-4) on your graph and see if the corresponding value of Y = 9.
