Answer:
1.Yes
2.Yes
3.No
4.No
5.Yes
Step-by-step explanation:
Just plug in the values of x and y for each set of coordinates.
Example from the first one
4x=y
4(5)=20
20=20 True
make sure all are valid by plugging in the next set of coordinates
4(6)=24
24=24 True
4(7)=28
28=28 True
and so forth with each equation plug in the coordinates
Answer:
Adults $ 17
Students: $8
Step-by-step explanation:
Adults: x
Students: y
a) 25x + 31y = 673
b) 27x +31y = 707
Elimination:
a) -1(25x + 31y = 673) = -25 -31y = -673
a + b
= (-25 -31y = -673) + (27x + 31y = 707)
= 2x = 34
x = 34/2
x = 17
Substitution a or b:
a) 25(17) + 31y = 673
425 + 31y = 673
31y = 673 - 425
31y = 248
y = 248/31
y = 8
