60 points and brainliest

Hey there! I'm happy to help!

First, let's find the slope. To find it, you divide the difference in two y values by the difference in the corresponding x values.

The x values are what you can choose. You can choose the number of minutes you choose, but you cannot directly choose the cost. You control the minutes, which dictates what the cost is. So, the minutes are our x values and the costs are our y values.

Let's use the points (500,62) and (750,77).

We subtract the y values.

77-62=15

We subtract the x values.

750-500=250

We divide these.

15/250=0.06

This means that our slope is 0.06, which means that for every minute the cost goes up by six cents.

The slope intercept equation is y=mx+b. The m is slope and b is y-intercept. We already have the slope, but we need the y-intercept. We can plug in the slope and one point on the line to solve for b.

62=0.06(500)+b

Flip the equation so b is on the left.

0.06(500)+b=62

30+b=62

Subtract 30 from both sides.

b=32

Therefore, our equation is y=0.06x+32.

Have a wonderful day! :D

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
