Y=5x-5y-5x=10 is the awnser for this one
This is easy all you have to do is plug in -3 into x^2
f(-3)=(-3)^2=(-3)(-3)=9
Answer: f(-3)=9 :)

The equation can be simplified by dividing both sides by 2
remember, anything times 0 is 0.
4x + 3y = 24
Now plug in values
if x = 0;
4(0) + 3y = 24
3y = 24
y = 8, this is the first answer
if y = 0;
4x + 3(0) = 24
4x = 24
x = 6, this is the second answer
if x = 12;
4(12) + 3y = 24
48 + 3y = 24
3y = -24
y = -8, this is the third answer.

2x = 4 Rules of Algebra
x = 2
Answer:
Step-by-step explanation:
Parameterize the ellipse as (acos∙,bsin∙). Take points P:=(acosp,bsinp) and Q:=(acosq,bsinq) on the ellipse, with midpoint M:=(P+Q)/2.
If |PQ|=2k, then
a2(cosp−cosq)2+b2(sinp−sinq)2=4k2
The coordinates of M are
xy==a2(cosp+cosq)b2(sinp+sinq)
