Is 4(4a+20b) equivalent to 16a+24b

1 answer:

7 0

No.

When you are distributing, you are multiplying to each monomial

4(4a) = 16a

4(20b) = 80b

16a + 80b is your actual answer

hope this helps

Write the slope-intercept from of the equation of the line described. Through (-2, -1) perpendicular to y = 1/4x

Feliz [49]

Step-by-step explanation:

Slope Intercept Form is "y = mx + b"

What it means?

"m" - slope

"b" - y intercept (0,b)

So, we are given the slope, but not the y intercept..

For now, lets fill in the slope.

y = 1/4x + b

We are given a coordinate pair (-2,-1)

Fill it into the equation and solve for b.

-1 = 0.25(-2) + b

-1 = -0.50 + b

- 0.50 = b

We now have the value of "B"

Fill in the rest of the equation:

y = 1/4x + -.50

^ I think that is correct, sorry if it's wrong.

What value represents the vertical translation from the graph of the<br> (x+5)2+3?<br> 0 -5<br> O-3

neonofarm [45]

Answer:

The value 3 represents the vertical translation upwards of $f(x)$ to $g(x)$

Step-by-step explanation:

The question is incomplete or missing data.

The correct question

What value represents the vertical translation from the graph of the parent function $f(x) = x^2$ to the graph of the function

$g(x) = (x + 5)^2 + 3$ ?

Given functions:

Parent function

$f(x) = x^2$

Translated function

$g(x) = (x + 5)^2 + 3$

Translation rules

For horizontal shift

$f(x)\rightarrow f(x+c)$

If $c>0$ the function shifts $c$ units to the left.

If $c$ the function shifts $c$ units to the right.

For vertical shift

$f(x)\rightarrow f(x)+c$

If $c>0$ the function shifts $c$ units to the up.

If $c$ the function shifts $c$ units to the down.

From the functions given the translation rule can be given as:

$f(x)\rightarrow f(x+5)+3$

$g(x)=f(x+5)+3$

This shows the graph is shifted left by 5 units and upwards by 3 units.

Thus the value 3 represents the vertical translation of $f(x)$ to $g(x)$

Let U={b, c, d, e, f, g, h} and A={b, f, g, h}. Use the roster method to write the set A'

podryga [215]

The roster method to write the set A' will be {c, d, e}.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

Let U = {b, c, d, e, f, g, h} and A = {b, f, g, h}.

The roster method to write the set A' will be given as,

A' = U - A

A' = {b, c, d, e, f, g, h} - {b, f, g, h}

A' = {c, d, e}

The roster method to write the set A' will be {c, d, e}.

More about the sets link is given below.
