12 + (–8) = 4
25 = 5(5)
8 + 0 = 8

6.D
7.C
8.C
9. (SA) the (4,1) are an ordered pair
the format for an ordered pair is (x,y)
so 4=x and 1=y putting in these values will give us 1=3(4)+1 and as you can see this is NOT TRUE
10.(SA) c-2.50 D where C is the cost. you can pick any number for D. after you do this you can solve for the cost of C

Answer 1

#1 ok
#2-8 ¿quien sabe?

#9 (4,1) is an ordered pair.
no idea which equation is is supposed to fit
It certainly does not satisfy y=3x+1

#10 true
#9
