I need to find the slope and b <br> Y=mx+b <br> HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20

Your state charges 5% sales tax on nonfood items. You're buying a light bulb for $3.00, cereal for

dimulka [17.4K]

We first add the tax to the non-food items. We have ($3.00+$.50)*1.05=($3.50)*1.05=$3.675 (Which can be rounded up to $3.68, since we can't have a fraction of a cent).

Now, we add the cost of the food to $3.68. As a result, we have $3.68+$2.50=$6.18 as the total bill.
