Answer:

Simplifying

2x(3x + -8) = 0

Reorder the terms:

2x(-8 + 3x) = 0

(-8 * 2x + 3x * 2x) = 0

(-16x + 6x2) = 0

Solving

-16x + 6x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2x'.

2x(-8 + 3x) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve:

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Subproblem 2

Set the factor '(-8 + 3x)' equal to zero and attempt to solve:

Simplifying

-8 + 3x = 0

Solving

-8 + 3x = 0

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 3x = 0 + 8

Combine like terms: -8 + 8 = 0

0 + 3x = 0 + 8

3x = 0 + 8

Combine like terms: 0 + 8 = 8

3x = 8

Divide each side by '3'.

x = 2.666666667

Simplifying

x = 2.666666667

Solution

x = {0, 2.666666667}

Answer:

A is $0.45 B is 2 ounces

Step-by-step explanation:

A when you divide the cost by the ounces or $5.40 by 12 ounces you get $0.45 per ounce.

B $0.45 times 2 equals 90 cents and you cannot go over 1 dollar.

C you should be to do along with D with this information.

Please do #4 It’s it the one on the bottom

spin [16.1K]

We need to graph this equation:

$16x+2y=300$

Its solutions are the points through which it graph passes. Since it's a linear equation its graph is a straight line and we only need two of its points to draw it. But before graphing let's re-write the equation. We can substract 16x from both sides:

$\begin{gathered} 16x+2y=300 \\ 16x+2y-16x=300-16x \\ 2y=300-16x \end{gathered}$

And we divide both sides by 2:

$\begin{gathered} \frac{2y}{2}=\frac{300-16x}{2}=\frac{300}{2}-\frac{16x}{2} \\ y=150-8x \end{gathered}$

So now with this equation if we pick two random x values we'll get their corresponding y values. This way we'll find two points that are part of the graph which is the line that passes through both. We can begin with x=0:

$y=150-8\cdot0=150$

So the first point is (0,150). Then we can take x=10 and we get:

$y=150-8\cdot10=150-80=70$

So the second point is (10,70). Then the graph is the line that passes through points (0,150) and (10,70). In order to represent it

alina1380 [7]

Answer:

a. 13.7084 oz.

Step-by-step explanation:

Formula for Lower Control Limit =

(LCL = x-bar - A²R-bar)

x - bar = 14 oz

A2 = 0.729

R - bar = 0.4 oz

= 14 - 0.729 × 0.4

= 14 - 0.2916

= 13.7084oz

PLEASE HELP ASAP!!! (No links)

marta [7]

Answer:

No it is not a solution

Step-by-step explanation:

To solve this, you should replace your (x,y) with (8,3)- 8 being your x value and 3 being your y value.

So this inequality, your y value is supposed to be bigger than the value of whatever 3x-4 equals.

So, your inequality should be 3>3(8)-4

3*8=24-4=20

So is 3>(greater than)20? No. Which then means that (8,3) is not a solution because it would make the inequality not true.

Hope this helps!

Step2247 [10]

6 cds total was 85.75 and there was a 5.04 tax so take 85.75 - 5.04 = 80.70
80.70÷6= 13.45
