Answer:

Hey there!

3/4(-24x - 16)

DISTRIBUTE 3/4 WITHIN PARENTHESES

= 3/4(-24x) + 3/4(-16)

= -18x - 12

Therefore, your answer is: -18x - 12

Good luck on your assignment and enjoy your day!

How do I divide a fraction to a decimal

Answers

A fraction is just a short way of showing division. When you see a fraction,
it's really saying "the top number divided by the bottom number".

If you take those two numbers and DO the division, the answer to the division
will be the decimal form of the fraction.

You divide the top by the bottom for example

Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = -8f(x)?

Answers

Answer:

reflection over the x-axis and a vertical compression by a factor of 8

Step-by-step explanation:

The parent function is given as

$f(x) = x$

The transformed graph has equation:

$g(x) = - 8f(x)$

The factor of 8, indicates a vertical stretch.

The negative sign indicates a reflection in the x-axis.

Therefore the transformation is a reflection over the x-axis and a vertical compression by a factor of 8.

Answer: shrunk vertically over the y axis

How many ml of 1:4 solution and how many ml of sterile water are needed to prepare 600 ml of 1:20 solution ?

Answers

Answer:

Approximately 143 mL of 1:4 solution and 457 mL of water

Step-by-step explanation:

A 1:4 solution has a concentration of 1/(1+4) = 1/5 or 20%.

Similarly, a 1:20 solution has a concentration of 1/(1+20) = 1/21 or 4.76%.

If x is the mL of 20% solution and y is the mL of water, then:

x + y = 600

1/5 x = 1/21 (600)

Solve:

x = 5/21 (600)

x ≈ 143

y ≈ 457

You need approximately 143 mL of 1:4 solution and 457 mL of water.
