Answer:

Plan a

Step-by-step explanation:

plan a costs $15, plus the amount that it would cost for 500 minutes, which is $25. (0.05*500=$25). $15+$25=$40.

If she chose plan b, it would cost $80, because $5+ (0.15*500)=$80.

Plan c would cost $60, by plugging in the numbers to the same function above.

Plan d would cost $120

Lets use 500 minutes and solve for each company:

Plan A = 15 +0.05(500) = 15 + 25 = 40

Plan B = 5 + 0.15(500) = 5 + 75 = 80

Plan C = 10 + 0.10(500) = 10 + 50 = 60

Plan D = 20 + 0.20(500) = 20 + 100 =120

Plan A is the most cost effective.

I need help making a coordinate proof and it starts with if a quadralateral, then its diagnoles are perpendicular.
zlopas [31]

Answer:

There are a number of ways to show whether a quadrilateral placed on a coordinate plane is a parallelogram or not. Here are a few ways:

1. Show that both pairs of opposite sides are congruent.  

2. Show that both pairs of opposite sides are parallel

3. Show that a pair of opposite sides are congruent and parallel

4. Show that the diagonals bisect each other.

In this activity, we will use the Distance, Midpoint and Slope Formulas that we learned in Algebra 1 to show congruent, bisected and parallel segments.

One railroad track was laid out on the line y = 8x - 2 by the engineers in charge. Which of the following lines could have been
kvv77 [185]
Y = 8x - 2.....slope here is 8. A parallel line will have the same slope.

The other line would be : y = 4 + 8x (or y = 8x + 4).....because they both have the same slope, which makes the lines parallel to each other

Answer:

3m² - 6

Step-by-step explanation:

Summing the 2 expressions

2m² + 3m - 4 + m² - 3m - 2 ← collect like terms

= (2m² + m²) + (3m - 3m) + (- 4 - 2)

= 3m² + 0 + (- 6) = 3m² - 6
