Answer: ever got the answer?
Step-by-step explanation:
Answer:
There are 5 faces, 5 vertices, and 8 edges, so all of that together is 18
Y = 6x - 11
-2x - 3y = -7
Let's use substitution:
-2x - 3y = -7
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
-20x = -40
x = 2
----
y = 6x - 11
y = 6(2) - 11
y = 12 - 11
y = 1
----
y = 6x - 11 => 1 ? 6(2) - 11 => 1 = 12 - 11 <--True
-2x - 3y = -7 => -2(2) - 3(1) ? -7 => -4 - 3 = -7 <--True
Answer:
x = 2
y = 1
Hope this helps!
Answer:
i think its 20 too, tho good luck
Step-by-step explanation:
Answer:
x=-3
Step-by-step explanation:
So usually you have an equation and it will have f(x)=-3.
equation: f(x)=2x+4-3+x.
You will then plug -3 into the x spots.
f(x)=2(-3)+4+3+-3=-2
Hope this helps.
