Answer:

0.15*t < 5.00

33 texts

Step-by-step explanation:

given : $0.15 per text; unlimited cost is $5.00

# of texts = t

0.15*t < 5.00

t < 33.33; since you cannot make 33.33 texts i will round down to 33 texts.

Basically you can send or receive up to 33 texts and it will be cheaper than $5.00

0.15(33) = $4.95

at 34 texts, 0.15(34) = $5.10

How many x intercepts appear on the graph of this polynomial function?
MArishka [77]
f (x) = x ^ 4-x ^ 3 + x ^ 2-x 
 For this case what we can do is graph the function and see the behavior of it.
 We have then that the function grows upwards (see attached image)
 It has two cutting points with the x axis in:
 x = 0
 x = 1
 Therefore, the other roots of the polynomial are imaginary.
 Answer:
 2 x intercepts appear on the graph of this polynomial function

Holly had 30 pencils.she gave 6 pencils to her friends .3/8 of her pencils need to be sharpened.How many of Holly’s pencils need
mafiozo [28]
This is the concept of algebra. Given that Holly has 30 pencils, the total number of pencils that Holly remained with after she gave her friends 6 pencils are:
Total=30-6=24 pencils 
The fraction of pencils that need to be sharpened is 3/8
The number of pencils represented by this fraction will be:
(fraction of un-sharpened pencils)×(total number of remaining pencils)
3/8×24
=9 pencils
therefore we conclude that 9 pencils are not sharpened.
