For this case we have the following expression:

$14 + 3x - 7 = 7x + 7 - 4x$

To answer the question, what we must do is rewrite both sides of the equation.

For this, we apply the associative property.

We have then:

$3x + (14-7) = (7x-4x) + 7$

Rewriting we have:

$3x + 7 = 3x + 7$

Since both sides of the equation are equal, then the expression is always true.

Answer:

A) Always

Answer:

x = - 2, x = 7

Step-by-step explanation:

Given

f(x) = 4x² - 20x - 56

To find the zeros let f(x) = 0, that is

4x² - 20x - 56 = 0 ( divide through by 4 )

x² - 5x - 14 = 0 ← in standard form

(x - 7)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 7 = 0 ⇒ x = 7

A line passes through the point (9,1) and has a slope of 2.Write an equation in slope-intercept form for this line.

bogdanovich [222]

Answer:

y = 2x-17

Step-by-step explanation:

We have a point and a slope, we can write the equation in point slope form and then convert to slope intercept form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y-1 = 2(x-9)

Distribute

y-1=2x-18

Add 1 to each side

y-1+1 = 2x-18+1

y = 2x-17

This is slope intercept form

pls help no one will how do estimate the numbers im about to give you by rounding to the nearest integer 15.23 - 6.835 and 6.88

gayaneshka [121]

I think it's just 15, -7, 7, -8, and 80.
I am probably wrong though,
Is it all one long equation with the plus and minus signs?

I can’t figure out this answer I’ve gotten so many and it seems non of them work

Mandarinka [93]

The quotient is 0.20125.

Solution:

Divide .03220 by .16

This can be written as

$$\frac{\cdot 03220}{\cdot 16}$

To divide this, we first remove the decimal term.

To remove decimal in denominator multiply and divide by 100.

$$\frac{\cdot 03220}{\cdot 16}\times \frac{100}{100}=\frac{3.22}{16}$

Now, divide 3.22 by 16.

The quotient is 0.20125.

What is the simplified form of the following expression? 4/7^3

timofeeve [1]

If your question is :
$\frac{4}{7^3}$

Then the answer is:
$\frac{4}{7*7*7} = \frac{4}{343}$

If your question is:
$(\frac{4}{7}) ^{3}$

Then the answer is:
$\frac{4*4*4}{7*7*7} = \frac{64}{343}$
