Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
18 × 5 = 90
90%30=3
3×6=18
x(8;2)
i think that
0
- Plot each point on the graph corextly using (x,y).
- The line should go verticle
- Since x doesnt change, there is no slope / the line will go up and down infinate
