Simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2. Which statements are true about the process and simplified product? Select three options.

The term –2(x – 2)2 is simplified by first squaring the expression x – 2.
The simplified product is a binomial.
After multiplying, the like terms are combined by adding and subtracting.
The parentheses are eliminated through multiplication.
The final simplified product is –28x2 +8x – 8.

Answer:

The second one

Step-by-step explanation:

a linear function is one who's graph is a straight line.

A parabola is not linear.

Anything in the form k/x is not linear either.

5/6x = y-4

gives

y = 5/6x+4, which is a linear equation

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

[tex]V = \frac{4}{3}\pi r^3[/tex]

Putting the known values

[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Answer:

Step-by-step explanation:The answer is - 12 because the temperature started changing when it raised 3+ and then it changed again by dropping -15 so, then you do 3-15 and that equals (-12).

Answer:

Greatest Common Factor

Step-by-step explanation:

Let [tex]55\cdot x^{3}-40\cdot x^{2}[/tex], we proceed to demonstrate the appropriate form to factor the polynomial:

1) [tex]55\cdot x^{3}-40\cdot x^{2}[/tex] Given.

2) [tex](5\cdot 11)\cdot (x^2\cdot x) +[5\cdot (-8)]\cdot x^{2}[/tex] Definition of multiplication and subtraction/[tex]a^{b+c} = a^{b}\cdot a^{c }[/tex]/[tex]-a\cdot b = (-a)\cdot b[/tex]/Associative property

3) [tex](5\cdot x^{2})\cdot (11\cdot x)+ (5\cdot x^{2})\cdot (-8)[/tex] Commutative and associative properties

4) [tex]5\cdot x^{2}\cdot (11\cdot x-8)[/tex] Distributive property/Definition of subtraction/Result

Hence, we conclude that this polynomial can be factored by Greatest Common Factor.

Answer:

[tex]3\frac{1}{2} hours[/tex]

Step-by-step explanation:

You have to subtract 2 1/2 from 6 and that will equal 3 and 1/2.

Answer:

75%

Step-by-step explanation:

6 - 3/2 is 4.5.

So the computer has 4.5 hours.

the battery will last for 6 hours so every hour on the computer is 100/6 percentage, which is 16.6666666667.

Finally multiply 16.6666666667 and 4.5 and you will get 75%

Your final answer would be 75%

Answer: 40/10=4

That means 10% of 40 is 4.

Know that means you have to times 4 by 8

4x8=32

Now you know what 80% of 40 is.

Now we need to know what the 5% is. So if 4 is 10% . 5% must be 2.

Next we have to add 2 to 32.

32 + 2 = 34

Answer is 34

Answer:

[tex]m = \frac {1}{4}[/tex]

Step-by-step explanation:

Slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here

[tex](x_1, y_1) = (-3, -1) \ \ and \ \ (x_2, y_2)= (5, 1)[/tex]

Slope can be calculated as

[tex]m = \frac{1-(-1)}{5-(-3)}[/tex]

[tex]m = \frac{2}{8} \\m = \frac {1}{4}[/tex]

Answer:

No Solution

Step-by-step explanation:

For system of equations, you must equal the equations to each other like shown below:

[tex]3x + 1 = 3x + 7[/tex]

Solve for x by subtracting 3x from both sides of the equation:

[tex]1[/tex] ≠ [tex]7[/tex]

x= -7      

Step-by-step explanation:

now that you know the value of x, rewrite the equation, if -7 + 9=2, then -7 + 9 - 9 = 2 -9. now that its easier to understand, add and subtract to get you answer, -16

Answer:

E. 11

Step-by-step explanation:

Replace the m with 11.

11-8[tex]\leq[/tex] 2  this would simplify to

3 [tex]\leq[/tex]2 which is false.

However if you took m and replaced it with 10

10-8[tex]\leq[/tex]2 and simplified

2[tex]\leq[/tex]2 which is true. Therefore any number 10 or lower would make this true.

Yes

Step-by-step explanation:

Answer:

y = 32x + 198

Step-by-step explanation:

The fastest way to go about this is to establish "m" and plug in the coordinates you want.

y = 32x + b

6 = 32 (-6) + b

6 = -192 + b

198 = b

y = 32x + 198
