One way is subsitute
I like solving
so
what you do is this
add the equaitons to gether to eliminate x
2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5
sub back
2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x
the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1
so then D is the answer
Answer:
None of the above.
The answer is 8.4 which is <u>greater than 8 and less than 9</u>. But that option isn't there. Therefore, the answer is none of the above.
Sin = opposite / hypotenuse
cos = adjacent / hypotenuse
using pythagoras theorem =
adjacent = 5^2-3^2
= 16
= square root 16
=4
cos x = 4/5

Answer:
Step-by-step explanation:
eq. of line parallel to AB is y=2x+a
if it passes through (3,-2) then
-2=2×3+a
a=-2-6=-8
y=2x-8
