Answer:
y = 3x + 3
Step-by-step explanation
Values on the y-axis are increasing by 3, while values on the x axis are increasing by 1, so the slope is 3/1 or just 3
To find b, you the slope, 3, from the 6. You also subtract 1 from 1 in the x-collum. You do this to find the y-intercept, or when x=0.

51= 1/2(160-x)
102=160-x
x=160-102=58
Answer:
Step-by-step explanation:
1) Let x be the number of adults and y be the number of students
x + y = 8 --------------(I)
y = 8 -x
7.25x + 5.50y = 52.75 ----------------(II)
Substitute y = 8 -x in equation (II)
7.25x + 5.5*(8 - x) = 52.75
7.25x + 5.5*8 - x*5.5 = 52.75
7.25x + 44 - 5.5x = 52.75
<u>7.25x - 5.5x</u> + 44 = 52.75
1.75x + 44 = 52.75
1.75x = 52.75 - 44
1.75x = 8.75
x = 8.75/1.75
x = 5
Plugin x = 5 in equation 1
y = 8 - 5
y = 3
2) x = y + 24
x + y = 180 {Supplementary}
y + 24 + y = 180
2y + 24 = 180
2y = 180 - 24
2y = 156
y = 156/2
y = 78
x = 78 + 24 = 102

I have tried solving each one in the right order and I keep getting answers that aren't options.
I will put the answers I got but none of them match up.
-5-(32+2)
-5-(34)= -39
22-3⋅6
22-18=4
-2+4⋅32-6
-2+128-6
126-6= 120
5+42÷2(3)
5+42÷6
5+7=12
I have done the math on my own and used desmos calculator these are the answers that come up. I'm sorry.
