The formula you can use for this is y=2/3×-5
Where the y is the cost of cats food and x is the cost of the dogs food
Step-by-step explanation:
spending 3 parts and saving 2 parts means that there are 3+2 = 5 parts in the whole.
the whole being $100.
one of the 5 parts is then 100/5 = $20.
so, she spent 3×20 = $60 and saved 2×20 = $40.
Answer:
50,75,and 100 there's supposed to be a 20 too but it's not there but oh well
X=34
First add like terms in the equation so that you get the equation 3x-2=100. Next add 2 on both sides so that you then get 3x=102. Lastly divide by 3 on both sides to isolate x. You would then get x=34.
You'd have to find slope so you would use y1-y2 over x2-x1 so itd be 4-4 over 9-2 thatd equal 0/7 thats ur slope. using slope intercept form y=mx+b plug in ur slope y=0/7 x + 4 (y- intecept) then youd subtract the 0/7 x from both so youd have -0/7x+y=4 and that is in standard form.
