What is the simplified form of the quantity of x plus 6, all over the quantity of x plus 4 + the quantity of x minus 3, all over
Rina8888 [55]
\frac{x+6}{x+4}  +\frac{x-3}{3}

make denomenators the same

we have
x+4 and 3
times the fraction with x+4 in denomenator with the fraction 3/3
times the fraction with 3 in denomenator with the fraction x+4
we get
\frac{3x+18}{3x+12}  +\frac{x^2+x-12}{3x+12}
since common denoms, can add them to get
\frac{3x+18+x^2+x-12}{3x+12}
\frac{x^2+4x+6}{3x+12}
that is simplified

A wallet contains $460 in $5, $10, and $20 bills. The number of $5 bills exceeds twice the number of $10 bills by 4, and the num
Butoxors [25]

Answer:

Number of $5 bills = 32

Number of $10 bills = 14

Number of $20 bills = 8

Step-by-step explanation:

Let x number of $5, y number of $10 and z number of $20

The number of $5 bills exceeds twice the number of $10 bills by 4.

Therefore, x = 2y + 4

The number of $20 bills is 6 fewer than the number of $10 bills.

Therefore, z = y - 6

A wallet contains $460 in $5, $10, and $20 bills.

Therefore,

5x + 10y + 20z = 460

Substitute x and y into equation

    5(2y+4) + 10y + 20(y-6) = 460

10y + 20 + 10y + 20y - 120 = 460

                           40y - 100 = 460

                                    40y = 460 + 100

                                    40y = 560

                                      y = 14

  • Put the value of y into x = 2y + 4 and solve for x

                                      x = 2(14) + 4

                                      x = 32

  • Put the value of y into z = y - 6 and solve for z

                                      z = 14 - 6

                                      z = 8

Hence, the each type of bills,

Number of $5 bills = 32

Number of $10 bills = 14

Number of $20 bills = 8

What type of transformations have occurred in the function shown below?
Liono4ka [1.6K]

Using shifting concepts, it is found that the correct option is:

  • Vertical stretch, horizontal shift left, vertical shift up.

The original function is:

y = \sqrt{x}

  • The original function was multiplied by 2, hence there was a <em>vertical stretch</em> by a factor of 2.
  • x \rightarrow x + 1, hence, there was an horizontal shift left.
  • 2 was added to the function, hence, there was a <em>vertical shift up.</em>

To learn more about shifting concepts, you can take a look at brainly.com/question/24465194
