The answer is √3. This is because √3 is already an irrational number and if you multiply it but either -5/9 or add it by 4, the product or sum will not terminate, nor repeat, or is able to turn in to a fraction

A cell phone plan charges $45.50 a month, plus $0.05 per text message. Write and graph an expression to find how many text messa

scoundrel [369]

Answer:

289 messages

equation: $y=0.05x+45.5$

graph: attached below

Step-by-step explanation:

We can write this in slope-intercept form, or $y=mx+b$ . Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.

Plugging in these numbers, we get $y-0.05x+45.5$

now we make y = 60, since that is the total amount they have

$60=0.05x+45.5\\14.5=0.05x\\x=290$

So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
