Answer:
x=-8,y=-2
Step-by-step explanation:
x=2+5 y
put value of x in eq 2
9(2+5 y)+8=32 y
18+45 y+8=32 y
26=32 y-45 y
26=-13 y
y=26/-13
y=-2
put value of y in eq x=2+5 y
x=2+5(-2)
x=2-10=-8
Answer:
-14x+6
Step-by-step explanation:
-3(4x-2)-2x
-12x+6-2x
-12x-2x+6
-14x+6
Answer:
FGH ~ KLJ
Step-by-step explanation:
You have to write the similarities in order. Meaning, each letter of the triangle must correspond with each letter of the other triangle, in order. So if ABC is similar to LMN, then A must be similar to L, B must be similar to M, and C must be similar to N.
So,F = 91 and K = 91. They are the first part of the similarity. Then, G and L both equal 65, so they are the second part. Finally, H and J both equal 24, so they must be the third part.
Therefore, FGH ~ KLJ.
(If you are wondering about the second part: " ≅ " means congruent to and " ~ " means similarity so the ~ symbol is the right one.)
I hope this helps! Good Luck!
Answer:
No..
Step-by-step explanation:
=> 7(2n+3) and 14n +3
(lets solve 7(2n+3) = 14n+3)
=> 7(2n+3)
=> (7×2n)+(7×3)
=> 14n + 21
•°• 7(2n+3) not equal to 14n +3
