Answer:
the answer is mx +B plus the quradratic formula
Answer:
y=10x+9; y=5x+9
Step-by-step explanation:
First of all, answers B and D are wrong because the formula is <em>y=mx+b. </em>So, that leaves us with a and C.
I couldn't find the slope because it was hard to see. try finding a point where it is clear what the points are and do change in y over change in x. I hope this helped at least a bit.
The answer is D. To solve 3/5 ÷ 4/7 you would change it to 3/5 × 7/4.
Answer:
x+y+2=-5 -2x-y+2=-1 x-2y-2=0 solve algebraically
x+y+2=-5 equation 1
-2x-y+2=-1 equation 2
x-2y-2=0 equation 3
Add equation 1 + 2+ 3
x+y+2=-5 + -2x-y+2+1 + x-2y-2
x+y+2= -7+2+1-2x+x+y
x+y+2= -4-x+y
x+y+2+4+x-y= 0
2x+6= 0
2x= -6
divide both side by 2
x= -3
from equation 1 insert x
x+y+2=-5
since x=-3
then, -3+2+y= -5
-1+y= -5
y= -5+1
y= -4
