Pls help i need to make a good grade on this thing im doing

Hi there!

it is y=80x

As you can see if x=80y then if we say that y=5 then x would be 400. Yiu can also tell that the if the x=5 then the y would be 500 so this wouldn’t make sense.

For B, you can tell that if x is 2 then y would be 160 which is correct if you can see..

Now we know that is B but let find out the others...

If x=y+80 then y always have to change... if x was 2 then the y would be 89 and if the x was 3 than y would be 160.

D is also the same as A but it’s the opposite.. y would be 160 then x would be 2. When y turned into 240 then x would be 3. It changes just like A.

Therefore, the equation that best represent this relationship is y=80x..

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
