BRAINLIEST FOR RIGHT ANSWER!!

Mathematics
1 answer:
julsineya [31]2 years ago
5 0

Answer: {\boxed{h(x+4)=\frac{9+3x}{8+x}}}

Concept:

In a function f(x), it represents a function in terms of x or for x. Therefore, to find the values in the function, substitute values within the parenthesis to solve.

Solve:

<u>Given information</u>

h(x)=\frac{-3+3x}{4+x}

<u>Need to find</u>

h(x+4)

<u>Substitute (x + 4) to the position of x</u>

h(x+4)=\frac{-3+3(x+4)}{4+(x+4)}

<u>Distributive property on the numerator</u>

h(x+4)=\frac{-3+3x+12}{4+(x+4)}

<u>Combine like terms</u>

h(x+4)=\frac{-3+12+3x}{4+4+x}

\boxed{h(x+4)=\frac{9+3x}{8+x}}

Hope this helps!! :)

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200.
worty [1.4K]

On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The linear equation is shown below.

\rm \dfrac{1}{5}x - \dfrac{2}{3}y = 30

The equation can be written as

\rm 3x - 10y = 450\\

For y = 15, the value of x will be.

\begin{aligned} \rm 3x - 10*15 &= 450\\\\\rm 3x - 150 &= 450 \\\\\rm 3x &= 600\\\\\rm x &= 200\\\end{aligned}

The value of x is 200.

Thus, option D is correct.

Divide using synthetic division: (2x^4+2x^3+-12x^2+x+6)/(x+3)​
kap26 [50]

Synthetic division yields

..... ||   2    2   -12    1      6  

-3  ||        -6    12    0    -3

= = = = = = = = = = = = = =

..... ||   2   -4     0    1      3

which translates to

\dfrac{2x^4+2x^3-12x^2+x+6}{x+3}=2x^3-4x^2+1+\dfrac3{x+3}

Pls help
Tresset [83]

Answer:

Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.

Step-by-step explanation:

Jimmy reads a page, on average, every 20 seconds.

5 × 60 = 300

300/15 = 20

therefore, one page every 20 seconds

1:20

Carlo reads a page, on average, every 30 seconds.

6 × 60 = 360

360/12 = 30

therefore, one page every 30 seconds

1:30
