3x+2=x+6
subtract x from both sides,subtract 2 from both sides, gives you 2x=4,then divide by 2 on both sides and x will equal 2. Input the 2 for x and see if it will graph in a straight line on a graph.
So 8x^2+8x+8-(-9x^2+2x+5) is going to be
8x^2+9x^2+8x-2x+8-5
Giving you
17x^2+6x+3
1. Never; sample answer: A biased sample favors one or more parts of the population over others.
2. Never; Sample answer: A voluntary response sample involves only those who want to participate in the sampling.
Answer:
C=15
Step-by-step explanation:
If R=7.5 & C=2R, C=2(7.5) C=15
F(13) means x equals 13.
Replace x in the equation with 13 and solve:
-13 + 3 = -10
F(13) = -10
