Answer:
what do you need help with?
Answer: x=9,y=-1/3
Step-by-step explanation: This is for Q. 16
Rearrange terms to line up properly.
x-3y=10
x+3y=8
eliminate y terms
x=10
x=8 now add all like terms, remember it's a given that there's a one in
front of a variable.
2x=18 solve for x
x=9 now plug in the nine into one of the original eq.s and solve for y
9+3y=8
3y=-1
y=-1/3 always check solutions in both eq.s to vertify. they both work
I'm pretty sure it would be D
Answer:
16 I believer that's the power simbel correct
1:This is a parabola by the looks of the equation and the fact that it's a
satellite dish. The vertex of the equation is (-6,0) and the focus is
2/4, 1/2. 1/2 plus -6 is -5.5. the focus is (-5.5,0).
This answer is only true if the actual equation is y^2 not 2y
2:<span>y=-(x+3)^2/8+1
3:</span>This is the answer(–1.25, –3),
4:
answer is: x^2=-12y
