The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 230 minutes, the monthly cost will be $113.5. If the customer uses 720 minutes, the monthly cost will be $285. A) Find an equation in the form
y=mx+b
where x is the number of monthly minutes used and y is the total monthly of the Ringular plan.


y=

B) Use your equation to find the total monthly cost if 892 minutes are used.

If 892 minutes are used, the total cost will be
dollars

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
