Given:
The expression is 2(-9x+21) - (14-10x).
Explanation:
Simplify the expression by using distibutive property of multiplication.
So equivalnet expression is,
-8x + 28
Answer:
A option
Step-by-step explanation:
ΔMNO: ∠M=79°, ∠O=22°, then ∠N=180°-79°-22°=79°.
ΔGHK: ∠G=∠H=79°, then ∠K=180°-79°-79°=22°.
ΔPQR: ∠R=20°, ∠Q=79°, then ∠P=180°-79°-20°=81°.
ΔDEF: ∠E=82°, ∠F=22°, then ∠D=180°-82°-22°=76°.
Similar triangles have congruent angles, then
ΔMNO and ΔGHK are similar.
Answer:
26.58 this might be the answer
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Sin = adjacent ÷ hypotenuse
Sin 45 = x ÷ 9
0.71 = x ÷ 9
0.71 × 9 = x
x = 6.36
~6.
hope it helps. :)
didn't see the ordered pair part, sry: -5,2
Step-by-step explanation: when you're given a letter (y or x) to reflect on, on the graph, all you have to do is look at the direction the line's going in, and if the numbers on the side are positive or not
