(0,4) : not a solution
(-2,4) ; solution
(0,5) : solution
(-2,7) : solution
(-4,1) : not a solution
(-1,1) : not a solution
(-1.5,3.5) : solution

any point that falls in the grey area is a solution....if ur points lie on a dashed line, it is not a solution...but if ur points lie on a solid line, it is a solution

For f (x) = 4 x +1 and g(x) = x^2- 5, find (g/f)(x)
Lady bird [3.3K]

Answer:

The answer is: \frac{x^2-5}{4x+1}

Step-by-step explanation:

We are given: f(x)=4x+1 and g(x) = x^2-5

We need to find (g/f)(x).

Simply divide g(x) and f(x)\\.

Which equates to:

(g/f)(x)= \frac{g(x)}{f(x)} =\frac{x^2-5}{4x+1}

This cannot be simplified further, so it is the answer.

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.
sasho [114]

Answer:

  10.8

Step-by-step explanation:

E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...

  6 × 1.8 = 10.8 = G

__

If you like, you can write an equation relating G to E:

  E = kG

  10 = k(6)

  k = 10/6 = 5/3

Now for E = 18, we have ...

  18 = (5/3)G

  18(3/5) = G = 10.8

Katie completes 2/3 of a craft project in 3/4 of an hour. At this rate, what fraction of the craft project does Katie complete i
jonny [76]

Divide the quantity done by the time:

2/3 / 3/4

When dividing by a fraction flip it over and change divide to multiply:

2/3 x 4/3 = (2 x4) / (3x 3) = 8/9

In 1 hour she will complete 8/9 of the project.

2-V18 - 2/12 + 2V18 =
Zepler [3.9K]

Answer:

D=12/2

Step-by-step explanation:

Let's simplify step-by-step.

2−v18− 2 /12 +2v18

=2+−v18+ −1 /6 +2v18

(−v18+2v18)+(2+ −1 /6 )

v18+ 11 /6

D=Correcto

2-V^{18}-2/12+2V^{18}=12/2

v=1.082512
