Can someone write a story for the equation y=3x + 9 and solve it? Also for y=4x + 24, y= 7x +28, y= -6x + 18, and y=10x -100 pls answer ASAP at least answer 2 please and don’t troll and actually answer it pl

A cleaner charges $50 per hour and has cleaned 5 hours, made 9 extra dollars worth of tips.Count the amount of money she made (x stands for hours)

y = 150 + 9

y - 159

Step-by-step explanation:

Same thing wit heverything, srry but it will take a lot of time for more than 1 and isn't for giving answers for a lot of same thing- it's for learning on an example so I hope you understand why i didn't do the other ones.

Done! Hope you learned how to do this/understood this and have a great day!

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
