Answer 1

Answer:

A. B and D are functions

Step-by-step explanation:

Functions are either one-to-one or many-to one    (x-value --> y value)

C is not a function because   -3  (x) maps to 1 and also to 0 (y).

Given the function f(x) = 3|x – 2| 6, for what values of x is f(x) = 18?

Answers

The values of x in f(x) = 3|x - 2| + 6 when f(x) = 18 are 6 and -2

How to determine the value of x?

The function is given as:

f(x) = 3|x - 2| + 6

The value of f(x) is

f(x) = 18

So, we have:

3|x - 2| + 6 = 18

Subtract 6 from both sides

3|x - 2| = 12

Divide both sides by 3

|x - 2| = 4

Remove the absolute bracket

x - 2 = 4 or x - 2 = -4

Add 2 to both sides

x = 6 or x = -2

Hence, the values of x are 6 and -2

B. x² + 10x + 25
C. 3² + 75
D. 3x² + 30x + 75

Answers

Answer:

answer D

Step-by-step explanation:

3(x2+10x+25)

3(x^2 +2×5×x +25)3(x+5)^2
answer: 3x^2+30x+75 (choice D)

explanation: so 3(x+5)^2. distribute the power to both of the variable and number in the parenthesis. that will equal to 3(x^2+10x+25). now multiple the expression in the parenthesis, and you will get 3x^2+30x+75.

The powers will be added together not the numbers ( bases)

Answer:

  No

Step-by-step explanation:

An exponent signifies the number of times the base is a factor in the product. When products involving the same base are multiplied, the total number of factors is the sum of the number in each of those products.

  [tex]5^2=5\cdot5\\\\5^9=5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\\\\5^2\cdot5^9=(5\cdot5)\cdot(5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5)=5^{11}[/tex]

The base of the exponent in the product is the value that is a repeated factor. It is 5, not (5·5).

The product of two integers is -160 if one of them is 8 find the other​

Answers

Hey ! there

Answer:

Other number is -20

Step-by-step explanation:

In this question we are given that the product of two integers is -160 and one of them is 8 . And we are asked to find the other integer .

For finding the other integer we are assuming ,

Other integer as ' x '

And now we can find other Integer by making equation and solving it .

SOLUTION : -

Equation is :

[tex] \quad \dashrightarrow \qquad \: 8 \times x = - 160[/tex]

or ,

[tex] \quad \dashrightarrow \qquad \: 8x = - 160[/tex]

To isolate the variable x , We are dividing both sides by 8 :

[tex] \quad \dashrightarrow \qquad \: \dfrac{ \cancel{8}x}{ \cancel{8}} = \cancel{ \dfrac{ - 160}{8} }[/tex]

On simplifying it , We get :

[tex] \quad \dashrightarrow \qquad \: \red{\underline{\boxed{\frak{x = - 20}}}} \quad \bigstar[/tex]

Henceforth , the other integer is -20 .

Verifying : -

Now we are verifying whether our answer is wrong or right by substituting value of x in the equation . So ,

[tex]8 \times x = - 160[/tex]

Substituting value of x :

[tex]8 \times - 20 = - 160[/tex]

Multiplying 8 with - 20 :

[tex] - 160 = - 160[/tex]

[tex] \rm{L.H.S = R.H.S}[/tex]

Find the distance between the points given below. Round your answer to the nearest tenth.
A (0,6) and B (-3,-1)

Answers

Answer:

7.6

Step-by-step explanation:

We want to find the distance between (0,6) and (-3,-1)

We can find the distance between any two points using the distance formula

Distance between two points =

[tex] \sqrt{(x2 - x1)^{2} +(y2 - y1) {}^{2} } [/tex]

Where the values of x and y are derived from the the two points. (x1,y1) and (x2,y2)

Here the two points are (0,6) and (-3,-1)

So we have (x1,y1) = (0,6) so x1 = 0 and y1 = 6

And we have (x2,y2) = (-3,1) so x2 = -3 and y2 = -1

Now we plug in the values of x and y into the formula and evaluate to get the distance.

Again recall distance = √(x2-x1)²+(y2-y1)²

==> plug in x2 = -3 , x1 = 0, y2 = -1 and y1 = 6

Distance = √(-3-0)²+(-1-6)

==> evaluate operations inside of parenthesis

Distance = √(-3)²+(-7)²

==> evaluate all exponents

Distance = √9+49

==> and 9 and 49

Distance = √58 = 7.6 (rounded)

How many solutions does the following equation have? 3(2x−4) =2(3x−6)

Answers

Answer:

Infinitely many solutions

Step-by-step explanation:

Equations can either have no solutions, one solution, or infinitely many solutions.

No solutions: 2 = 6One solution: x = 2Infinitely many solutions: 2 = 2

Given: 3(2x − 4) = 2(3x − 6)

Distribute:

3(2x − 4) = 2(3x − 6)

3(2x) + 3(−4) = 2(3x) + 2(−6)

6x − 12 = 6x − 12

Dave loves underwater diving. His house boat is 250 feet above sea level. He jumped from that level. He went 600 feet below sea level. How many feet did Dave go under the water?

Answers

Answer:

600 feet

Step-by-step explanation:

I would just like to explain how this works with a visual (please enjoy my drawing <3 haha)

With my drawing we know that the bird is 150 feet above sea level, and the fish is 100 feet below sea level.

From the bird to the water it is 150 feet, from water to fish is 100 feet

From the bird to the fish it is 150 feet + 100 feet

This is equal to 250 feet,

so we know from the bird (150 feet above sea level) to the fish(100 feet below sea level).

Knowing this information we can easily answer this questionDave is 250 feet above sea level, and he went 600 feet nelow sea level, meaning he only went 600 feet under the water.

Write an equation for the line that has a slope of -2/3 and goes through the point (-6,8)

Answers

Answer:

The solution is in the image

Answer:

y = (-2/3)x + 4

Step-by-step explanation:

the equation of a line is given by the formula y = mx + b where m is the slope and b is the y intercept.

so,

y = (-2/3)x + b

to find b we plug in the values of x and y given by the point (-6,8)

8 = 4 + b

b = 4

so y = (-2/3)x + 4

Answers

Answer:

[tex]\sf X=\dfrac{2345}{9999}[/tex]

Step-by-step explanation:

Given:

[tex]\sf X=0.234523452345...[/tex]

Therefore, X is a recurring decimal (the decimal numbers 2345 repeat forever).

Converting a recurring decimal to a fraction

Let X equal the recurring decimal:

[tex]\implies \sf X=0.234523452345...[/tex]

Create another number with recurring 2345s by multiplying the above expression by 10000:

[tex]\implies \sf 10000X=2345.23452345...[/tex]

To solve these two equations and write X as a fraction, take away X from 10000X to remove all the recurring decimal places:

[tex]\large\begin{array}{r r l}& \sf 10000X & = \sf 2345.23452345... \\- & \sf X & = \sf \quad \:\:\:0.23452345.... \\\cline{2-3} & \sf 9999X & = \sf 2345\end{array}[/tex]

[tex]\implies \sf 9999X=2345[/tex]

Divide both sides by 9999:

[tex]\implies \sf X=\dfrac{2345}{9999}[/tex]

Therefore, 0.23452345... as a fraction is [tex]\sf \dfrac{2345}{9999}[/tex]

If the cans are divided evenly among the shelves, how many cans are on each shelf?

Cans for sale: 1,200
Shelves of cans: 10
Rows per shelf: 6

Answers

It’s 200 because 6x2 is 12 and we divided 1200 and 6 so that’s 200

To distribute 1,200 cans evenly among 10 shelves, with each shelf having 6 rows, we find that there are 120 cans on each shelf.

To find the number of cans on each shelf, we need to divide the total number of cans (1,200) by the total number of shelves (10) and the number of rows per shelf (6).

First, calculate the total number of cans in each shelf by multiplying the number of rows per shelf by the number of cans in each row:

Cans per shelf = Rows per shelf * Cans in each row

Cans per shelf = 6 * 200 = 1,200

Now, divide the total number of cans (1,200) by the total number of shelves (10):

Cans on each shelf = Total number of cans / Total number of shelves

Cans on each shelf = 1,200 / 10 = 120

So, there are 120 cans on each shelf when the cans are divided evenly among the shelves.
