Mathematics
1 answer:
Kobotan [32]3 years ago
8 0

Answer:

Hola

Step-by-step explanation:

Well if this is based off the first thing I answered, then 1. C

as I told you before, every time the x axis values go up one, the y values go up by x2 (aka times 2). Therefore it’s C.

2. It is linear because the unit change (amount it goes up aka slope) is the same since it’s alway x2. Hence the line on a graph would look linear

Given that f(x) = x2 – 5x – 14 and g(x) = x – 7, find (f +g)(x) and
Angelina_Jolie [31]

Answer:

(f+g)(x)=x^2-4x-21

Step-by-step explanation:

We are given:

f(x)=x^2-5x-14\text{ and } g(x)=x-7

And we want to find:

(f+g)(x)

This is equivalent to:

=f(x)+g(x)

Therefore, by substitution:

=(x^2-5x-14)+(x-7)

Rearranging gives:

=(x^2)+(-5x+x)+(-14-7)

Combine like terms:

=x^2-4x-21

A man receives an annual increase of #30000 and after a period of 10 years service, the man has the salary of #1014. Find his in
Paladinen [302]

I think you intended writing #30 as his pay rise instead of #30000. I solved the problem using #30 as his annual pay rise.

Answer:

The man's initial salary was #714

Step-by-step explanation:

Extracting the key information from the question:

*** A man got a pay raise for 10 years.

*** His current salary is #1,014

*** He gets a pay raise of #30 annually.

*** We are simply required to calculate his initial salary before he started receiving pay rise.

Now, To calculate his initial salary before he started receiving pay rise, let us denote that initial salary that we are currently unaware of by "a".

Since his salary as at today is #1,014 and he has also received this pay rise of #30 for 10 years, we can calculate his initial salary before he started receiving pay rise every year with the following equation:

a + 30(10) = 1014

That is -

Initial salary + [pay rise × number of years] = current salary.

a + 30(10) = 1,014

a + 300 = 1014

a = 1014 - 300

a = #714

Therefore the man's initial salary was #714
