Help PLSSSSSSSSSSSSSSSSS extra points

Mathematics
1 answer:
arlik [135]3 years ago
7 0

Answer:

85 messages

Step-by-step explanation:

The system of equations for this is

35 + .10x

18 + .3x

where x = the number of text messages

Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.

When you plug in 85, or x = 85, you get 43.5 for both equations because

35 + .10(85) = 43.5     18 + .3(85) = 43.5

Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

Which of the relations given by the following sets of ordered pairs is not a function?
-Dominant- [34]

Answer:

Hi, there your answer will be C.

Step-by-step explanation:

The reason why is because X(Input) can not be repeated the same

for example the coordiante( 1,3) and (1,4). See there are two ones which make them not function

Also, if you're having trouble with Functions and nonfunctions

REMEMBER THS

Function: X and y has to be separarte  and can't have the same X

NON-FUNCTION- WHEN X REPEATS ITSELF

Hope this helps :)

Novosadov [1.4K]
It will take her 8 weeks to save up enough money for the bike.

To get the answer first you have to subtract 125 from 245 to see how much money she still has to save then divide the answer which is 120 by 15 and you get 8. Hope this helps!!

Determine the product, h (x), of the linear and quadratic factors.
Wewaii [24]

h(x) =8x^3-19x^2+14x-3

Step-by-step explanation:

Given functions are:

f(x) = 8x-3\\g(x) = (x-1)^2

h(x)  is the product of g(x) and f(x)

h(x) = f(x) * g(x)\\= (8x-3)(x-1)^2\\= (8x-3)(x^2-2x+1)\\= 8x(x^2-2x+1)-3(x^2-2x+1)\\= 8x^3-16x^2+8x-3x^2+6x-3

Combining like terms

=8x^3-16x^2-3x^2+8x+6x-3\\=8x^3-19x^2+14x-3

Hence,

h(x) =8x^3-19x^2+14x-3
