Answer:

y=25x+40.50 is not the equation of proportional relationship because if you were to graph the equation, the line would not go through the origin of the graph. You can tell beause of the y-intercept that is given in the equation, 40.50.

Answer:

y=25x+40.50

Step-by-step explanation:

We have been given two equations. We are asked to choose the equation, which is not proportional.

We know that two proportional quantities are in form y=kx, where k is constant of proportionality.

We can see that the equation y=3.5x is a proportional equation, where constant of proportionality is 3.5.

We can see that the equation y=25x+40.50 is not a proportional equation as it has a constant.

Therefore, the equation y=25x+40.50 is not a proportional.

Answer:

1. f= 9

2. y= 10

3. h= 2.5

4. q= 10

5. m= 6

Step-by-step explanation:

1. you divide both sides by 3 to get f by itself

2. you divide both sides with 6

3. you subtract because it is the opposite of addition. you could also write 5/2 but that’s not simplified enough

4. 10 x 4 = 40 so 10 is the answer

5. you subtract both sides by 6 and get 24. 24 divided by 4 equals 6

Answer:

B. 88.5

Step-by-step explanation:

first we add all the numbers :

(79 +80 +92 +92 +81 +100 +88 +98 +71 + 100+91+90) over 12

= 1062 over 12

= 88.5

[why over 12? because there's 12 numbers]
