A phone company offers two monthly charge plans. In Plan A, the customer pays a monthly fee of and then an additional cents per

minute of use. In Plan B, the customer pays a monthly fee of and then an additional cents per minute of use. For what amounts of monthly phone use will Plan A cost less than Plan B? Use for the number of minutes of phone use, and solve your inequality for .

Plan A: y = 25 + .06m

Plan B: y = 29.70 + .05m

25 + .06m < 29.70 + .05m

.01m < 4.7

m < 470 minutes

Hope this helps!

:D

2. .8333333 repeated 3x1\3 is 1 the 1x5\6 is .83
3. Order of operations PMDOS 30\2 first giving you 15 then take 50-15=35
4. 10x1.5=15
5. 20+30 first because of order of operations then multiply by 10 giving you 500
6. 120 \ 12 = 10
7. 1 + 9 = 10
8. 0.15-0.02=.13x100 = 13
9. 4.9/0.07=70

. Which ordered pairs in the form (x, y) are solutions to the equation 7x – 5y = 28?

Brut [27]

we know that

If a ordered pair (x,y) is a solution of the equation, then the ordered pair must satisfy the equation

we have the equation

$7x-5y=28$

Let's verify all the cases to determine the solution to the problem.

<u>case A)</u> point $(-6,-14)$

Substitute the values of x and y in the equation

$x=-6\\y=-14$

$7(-6)-5(-14)=28$

$-42+70=28$

$28=28$ -------> is true

therefore

The point $(-6,-14)$ is a solution of the equation

<u>case B)</u> point $(-1,-7)$

Substitute the values of x and y in the equation

$x=-1\\y=-7$

$7(-1)-5(-7)=28$

$-7+35=28$

$28=28$ -------> is true

therefore

The point $(-1,-7)$ is a solution of the equation

<u>case C)</u> point $(4,10)$

Substitute the values of x and y in the equation

$x=4\\y=10$

$7(4)-5(10)=28$

$28-50=28$

$-22=28$ -------> is not true

therefore

The point $(4,10)$ is not a solution of the equation

<u>case D)</u> point $(7,9)$

Substitute the values of x and y in the equation

$x=7\\y=9$

$7(7)-5(9)=28$

$49-45=28$

$4=28$ -------> is not true

therefore

The point $(7,9)$ is not a solution of the equation

therefore

<u>the answer is </u>

$(-6,-14)$

$(-1,-7)$

What is the square root of 4/225

LuckyWell [14K]

2 / 15

This is simpler than you think. Just take the square root of the denominator and of the numerator and stick it back into fraction form. The square root of 4 is 2 and the square root of 225 is 15. Voila: 2 / 15.
