Explain how 50 tens x 4 hundreds = 40 tens x 5 hundreds

1 answer:

50 tens is equal to 500 because if you multiply a number by 10, you just add a 0 behind it.
4 hundreds is literally just 400.
So 500 x 400 = 200,000

40 * 10 = 400
5 * 100 = 500
400 x 500 = 200,000

so both sides are equal to 200,000 and therefore the equation is true.

Maria compared the slope of the function f(x)=(-6x-21) to the slope of the linear function that fits the values in the table bel

raketka [301]

Answer:

b. both functions have a negative slope

Step-by-step explanation:

The given function is

$f(x)=-6x-21$

This function is of the form $y=mx+b$ , where $m=-6$ is the slope and $b=-21$ is the y-intercept.

We can also determine the slope of the function in the table using any two points, say $(0,7)\:and\:(2,6)$ .

The slope formula is given by,

$m=\frac{y_2-y_1}{x_2-x_1}$ .

If $(x_1,y_1)=(0,7)\:and\:(x_2,y_2)=(2,6)$ , then,

$m=\frac{6-7}{2-0}$

$m=-\frac{1}{2}$ .

We can see that both functions have a negative slope.

The correct answer is B.

What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(−5x)?

Amiraneli [1.4K]

Answer:

C) horizontal compression and reflection across the y-axis

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.

Please see the attached image below, to find more information about the graph

The original equation is:

f(x) = 2x

The new equation is:

f(-5x) = 2(-5x)

f(-5x) = -10*x

The answer is

C) horizontal compression and reflection across the y-axis
