Which graph represents the solution to the given system?
y=-x+5
y=1/4x+10
Im rlly behind and need some help on the test .-.
@bruh bold of you to assume We are having kids
@bruh has now lost the ability to have children. Have a good day students! :)
can y'all just type the question out and then put the answer so there's no debating on who's right and who's wrongðŸ˜

23. y is less than or equal to x + 8 and y is greater than or equal to -3x - 8
good luck, guys! <3
its 2021 now and nobody knows if the answers are correct :/
In Eq2, replace Y with -x + 5:
-x + 5 = x/4 + 10.
Multiply both sides by 4:
-4x + 20 = x + 40,
X = -4.
In Eq1, replace X with -4 and solve for Y:
Y = -(-4) + 5 = 9.
Solution:(-4, 9).

where is a hero without cape when you need it ?
the test is different for everyone...
