Siri earns $6 a day for house sitting. She spends $10 to replace a vase she accidentally broke. Alexa has $50 from her birthday and she spends $4 a day on coffee. How many days, d will it take until the girls have the same amount of money?

6

Step-by-step explanation:

siri=6x-10

alexa= 50-4x

im making a table which is an easy way to tell or you can guess and check

X       S       A

 2     |    2    |42

  3    |   8     |38

   4   |     14   |34

  5    |   20     |30

   6   |     26   |26

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
