The vertex is (-1,-11).
Step-by-step explanation:
I don't know what the q value of this is, but I found the vertex for you.
I hope that this helps!
The answer is 10.2.
Since it's a percentage, you move the decimal two places to the left which gives you 0.12. Then, you multiply that by 85 and you get 10.2.
Multiply 2x-2y=10 by 2,
4x-4y=20,
given:4x-5y=17
y=3
pluck it in
2x-6=10
move the 6 to the right
2x=16
divide
x=8
y=3
Answer:
negative
Step-by-step explanation:
positive * positive = positive
negative * positive = negative
negative * positive = negative
Answer:

y = -9 + 75 = 66
x = 27-(-11) = 27 + 11 = 38
slope = 66/28
