Answer: 3x^3(x - 2)(x + 6)

Step-by-step explanation:

For this problem, you find a GCF first

The GCF in this case is 3x^3 since each term can be divided by both 3 and x^3

3x^3(x^2 + 4x - 12)

x * x = x^2

(-2 + 6) * x = 4x

-2 * 6 = -12

Since -2 and +6 work for the factors, the answer is 3x^3(x - 2)(x + 6)

If the number is, say, N, then “10 less than twice the number” is 2N - 10.

Pretty simple. take the number given, multiply it by 2, then subtract 10 from the answer.

If N is 7, then “10 less than twice the number” is 2*7 - 10 = 14 - 10 = 4.

Step-by-step explanation:

The initial amount is 55 gallons, and the rate is -3 gal/min.  So using slope-intercept form, the equation is:

f(x) = -3x + 55

To find the inverse function, switch x and y, then solve for y.

x = -3y + 55

3y = -x + 55

y = (-x + 55) / 3

f⁻¹(x) = (-x + 55) / 3

Evaluated at x = 15:

f⁻¹(15) = (-15 + 55) / 3

f⁻¹(15) = 40 / 3

The original function told us number of gallons f(x) at time x.

The inverse function tells us time f⁻¹(x) at number of gallons x.

So there are 15 gallons in the tank after 40/3 minutes, or 800 seconds.

Answer:

Step-by-step explanation:

Let be [tex]y = k\cdot x +1[/tex] the expression of the line, where [tex]x[/tex] and [tex]y[/tex] are the independent and dependent variables, respectively. If we know that [tex]x = 2[/tex] and [tex]y = -7[/tex], the value of [tex]k[/tex] is:

[tex]-7 = 2\cdot k +1[/tex]

[tex]2\cdot k = -8[/tex]

[tex]k = -4[/tex]

The equation of the line is [tex]y = -4\cdot x +1[/tex], which is graphed below.

The graph of equation of given line attached below.

Given that equation of line is,

                       [tex]y=kx+1[/tex]

since, line passes through [tex]M(2,-7)[/tex].

Substitute point  in given equation of line.

                   [tex]-7=2k+1\\\\2k=-8\\\\k=-8/2=-4[/tex]

So that, equation of line becomes,   [tex]y=-4x+1[/tex]

Answer:

3 hours working on problems, 1 hour reading

Step-by-step explanation:

From the given information:

We learned that If Nick can attempt more than 15 problems in an hour, working on problems will helo and aid further his grade for that particular hour than reading would.

We know that the marginal gain for three hours is greater than 15. This implies that Nick would get better by spending 3 hours on problem-solving and the rest 1 hour on reading since the marginal gain for that an hour is one problem solved. Hence, it will be advisable to spend it on reading.

Step-by-step explanation:

Answer:

M = - 3

Step-by-step explanation:

Find the Slope:

Slope is equal to the change in  y  over the change in  x

, or rise over run.

m  =  [tex]\frac{change in Y}{change in X}[/tex]

The change in  x  is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Substitute in the values of  x  and  y  into the equation to find the slope.

m = [tex]\frac{3-(9)}{4-(2)}[/tex]

Simplify.

m = [tex]\frac{-6}{2}[/tex]

m = -3

Answer:

2:1

Step-by-step explanation:

Since there are 4 apples and 2 bananas, the ratio of apples to bananas will be 4:2

This needs to be simplified, since both numbers are divisible by 2:

4:2 will simplify to 2:1

So, in simplest form, the ratio of apples to bananas is 2:1

In this context, this means there are 2 apples for every 1 banana in the fruit bowl.

The ratio of the apples to bananas in the fruit bowl is 2:1.

A ratio in mathematics shows how many times one number is contained in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Given that there are 4 apples, 5 oranges, and 2 bananas in a fruit dish. The ratio of apples to bananas will be 4:2 because there are 2 bananas and 4 apples.

This needs to be simplified since both numbers are divisible by 2:

4:2 will simplify to 2:1

Therefore, the ratio of apples to bananas in the fruit bowl is 2:1.

I did the quiz on Edg

Answer:

x=8

Step-by-step explanation:

you first have to multiply 3times3 and 3 times 4 to get the fraction off

then you bring down 4(x-3)=20

then you multiply 4 times x which you will get 4x then 4 times3 which equals 12 sso you will write it like this 4x-12=20

the you take -12 and add it to 20 and you will get 32

the you just divide 32 and 4 and it will give you the answer

to check it if its right you do 4(8-3)=20

Answer:

-4

Step-by-step explanation:

let x equal the unknown number

x-6 = 5(x + 2)

You need to distribute the 5

x-6 = 5x + 10

Then subtract x from 5x

-6 = 4x + 10

Subtract the 10 from -6

-16 = 4x

Divide

-4 = x

Step-by-step explanation:

Given that the logical statement is

"If a divides bc, then a divides b or a divides c"

we can see that a must divide one either b or c from the statement above

A) If a does not divide b or a does not divide c, then a does not divide bc.

This is False because a can divide b or c

 B) If a does not divide b and a does not divide c, then a does not divide bc.

this is True for a to divide bc it must divide b or c (either b or c)

C) If a divides bc and a does not divide c, then a divides b.

This is True since a can divide bc and it cannot divide c, it must definitely divide b

D) If a divides bc or a does not divide b, then a divides c.

This is True since a can divide bc and it cannot divide b, it must definitely divide c

E) a divides bc, a does not divide b, and a does not divide c.

This is False for a to divide bc it must divide one of  b or c
