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)

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

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

Answer:

Step-by-step explanation:

Area of rectangle is  b*h

so

a = (x-3)(x+7)

75 = (x-3)(x+7)

75 = x²+4x-21

0 = x²+4x-96

(x+12)(x-8)=0

x = -12, or x = 8

Answer:

-1/2

Step-by-step explanation:

it has to be a negative number since

every other number is negative

its a fraction since the numbers are decreasing

96 divided by 48 is 2

so the number being multiplied or ration must be -1/2

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

Hey ! there

Answer:

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 ,

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]

Verifying : -

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

Substituting value of x :

Multiplying 8 with - 20 :

Therefore , of answer is correct .

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

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

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.

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]

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.

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

Answer:

Infinitely many solutions

Step-by-step explanation:

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

Examples:

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
