Answer:
5x-2y=-20
Step-by-step explanation:
y-y1=m(x-x1)
y-5=5/2(x-(-2))
y-5=5/2(x+2)
y-5=5/2x+10/2
y-5=5/2x+5
y=5/2x+5+5
y=5/2x+10
y-5/2x=10
-5/2x+y=10
2(-5/2x+y)=2(10)
-10/2x+2y=20
-5x+2y=20
5x-2y=-20
Therefore x intercept(a) is <span>3
</span> and y intercept(b) is 3<span>
</span>.
Answer:
-14x-1+4x=3
Step-by-step explanation:
it's all in the pic
We have that
t²<span> – 81
</span>
we know that
A difference of two perfect squares, <span> (A</span>²<span> - B</span>²)<span> </span><span>can be factored into </span><span> (A+B) • (A-B)
</span> let
A²-------> t²
B²-------> 9²
then
(t² – 9²)------->(t+9)*(t-9)
the answer is
(t+9)*(t-9)
