Rewrite the equation B - 7,536 = 2t as a function of t.

Step-by-step explanation:

To find perimeter, you need to add all the sides of the shape.

The area of a traingle is 1/2 bh.

You must find the "b" in order to find the perimeter.

Example:

A triangle has an area of 18 cm^2.

Therefore, the triangle has a 6 cm base and 6 cm height.

Then multiply the base by three to get 18 cm. That is your perimeter.

Answer:

43.35pi m cubed

Step-by-step explanation:

Volume of a cylinder

= pi r^2 h

Where r = radius

h = height

Given r = 1.7m and

h = 15m

Volume = pi x (1.7)^2 x 15

= pi x 1.7 x 1.7 x 15

Multiply through

Volume = 43.35 pi m cubed

Final answer:

Mrs. Brown spent $8 at the store, which is found by subtracting her remaining amount of $8 from her initial amount of $16.

Explanation:

The amount of money Mrs. Brown spent at the store can be calculated by subtracting the amount she had after shopping from the amount she had before going to the store. Mrs. Brown had $16 before shopping and was left with $8 after shopping. Therefore, to calculate how much money she spent, we would perform the following subtraction:

$16 (before shopping) - $8 (after shopping) = $8 (spent)

Hence, Mrs. Brown spent $8 at the store.

Answer:

A. X= -9 hope this helps alot

The requried solution of equation 5x + 8 - 3x = -10 is x = -9. Option A is correct.

We can simplify the equation by combining like terms:

5x + 8 - 3x = -10

2x + 8 = -10

2x = -10 - 8

2x = -18

x = -18/2

x = -9

Therefore, the solution to the equation is x = -9.

Hence, the answer is option (A) x= -9.

Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

[tex]100\%+20\%=120\%=120/100=1.20[/tex]

The final price is equal to the original price multiplied by 1.20

so

[tex]1.20x[/tex]

2) The price of a video game decreases by 10%

so

[tex]100\%-10\%=90\%=90/100=0.90[/tex]

The final price is equal to the price at this moment multiplied by 0.90

so

[tex]0.90(1.20x)=1.08x[/tex]

we have that

[tex]1.08x=46.98[/tex]

solve for x

[tex]x=46.98/1.08\\x=\$43.50[/tex]

Answer: $24.50

Step-by-step explanation: $3.50 times 7 equals $24.50

Since the answer calls for a decimal, we will convert 1/10 into a decimal, which works out to be 0.1. Now, we multiply 0.1 by 0.08, which results in the decimal place moving one position to the left. Therefore, the answer is *0.008.*

Melissa and her younger sister are 5 meters apart.

In this scenario, Melissa's younger sister is directly to her right and her older brother is 12 meters directly ahead of her. Since her brother and sister are 13 meters apart, we can use the Pythagorean theorem to find the distance between Melissa and her younger sister.

Let's call the distance between Melissa and her younger sister 'x'. We can set up a right triangle with Melissa, her brother, and her sister as the vertices.

Using the Pythagorean theorem, we have:

x^2 + 12^2 = 13^2

Simplifying the equation, we get:

x^2 + 144 = 169

x^2 = 169 - 144

x^2 = 25

Taking the square root of both sides, we find:

x = 5

Therefore, Melissa and her younger sister are 5 meters apart.

This is just the difference of squares.

The expression [tex]X^2 - y^2[/tex] can be factored using the difference of squares rule, resulting in the Factoring form [tex](X - y)(X + y)[/tex].

The equation you're asking about, [tex]X^2 - y^2[/tex], is an example of a difference of squares, a key concept in algebra. In general, the formula [tex]a² - b²[/tex] can be factored into [tex](a - b) (a + b)[/tex]. So for the expression [tex]X^2 - y^2[/tex], we can apply this rule to factor it into [tex](X - y)(X + y)[/tex].

Here is a step-by-step explanation:

Identify that the equation is in the form of [tex]a²-b²[/tex], where 'a' is X and 'b' is y

Step-by-step explanation:

Use point slope form:  (y - y1) = m(x - x1)

y - 4 = 0(x + 7)

y - 4 + 4 = 0 + 4

y = 4

Answer:  y = 4

The function is not invertible if you think of it as

[tex]f:\mathbb{R}\to\mathbb{R}[/tex]

because it is not injective: [tex]f(x)=f(-x)[/tex]

So, if we restrict the domain to the positive numbers only:

[tex]f:\mathbb{R^+}\to\mathbb{R}[/tex]

Note that the range is actually [tex][9,\infty)[/tex], so we can be more precise and write

[tex]f:\mathbb{R^+}\to[9,\infty)[/tex]

To find the inverse, we solve the expression for x:

[tex]y=x^2+9 \iff y-9=x^2 \iff x=\pm\sqrt{y-9}[/tex]

But since we restricted to positive values of x, the inverse is

[tex]x=\sqrt{y-9}[/tex]

To find the inverse of the function f(x) = x² + 9, swap x and y and solve for y. The inverse function is f^(-1)(x) = ± √(x-9), with a domain restricted to x ≥ 9.

To find the inverse of the function f(x) = x^²+ 9, we need to switch the roles of x and y and solve for y. The given function is y = x² + 9. Swap x and y to get x = y² + 9. Rearrange this equation to solve for y in terms of x: y² = x - 9. Taking the square root of both sides gives us y = ± √(x-9). Therefore, the inverse function is f^(-1)(x) = ± √(x-9), and the domain is restricted to x ≥ 9.

If you add 3 to x you have [tex]3+x[/tex]

Subtract this from 1: [tex]1-(3+x)=1-3-x=-2-x[/tex]

Double this: [tex]2(-2-x)=-4-2x[/tex]

The required answer is 4 + 2x.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given expression is,

Add 3 to x subtract the result from 1 then double

Convert it to the numerical expression,

Add 3 to x = 3 + x

subtract the result from 1 = 3 + x - 1

⇒ subtract the result from 1 = 2 + x

Now double of result  = 2(2 + x)

⇒ double of result  = 4 + 2x

this is the required solution.

The solution for given equations [tex]-7x+2y=5[/tex] and [tex]3x-5y=-5[/tex] are x = -0.517 and y = 0.6896.

Step-by-step explanation:

The given is,

                            [tex]-7x+2y=5[/tex]..........................(1)

                              [tex]3x-5y=-5[/tex]........................(2)

Step:1

         Equation (1) is multiplied by 5    ( Eqn(1) × 5)

                        [tex]-35x+10y=25[/tex].........................(3)

         Equation (2) is multiplied by -2  ( Eqn (2) × -2 )

                          [tex]-6x+10y=10[/tex].........................(4)

Step:2

         Subtract the equation (3) and (4),

                            [tex]-35x+10y=25[/tex]

                              [tex]-6x+10y=10[/tex]

                ( - )

    [tex](-35x+6x)+(10y-10y)=(25-10)[/tex]

                                     [tex]-29x=15[/tex]

                                          [tex]x = - \frac{15}{29}[/tex]

                                          x = -0.517

          From the x value equation (2) becomes,

                     [tex]3(-0.517)-5y=-5[/tex]

                          [tex]-1.551-5y=-5[/tex]

                                       [tex]-5y = (-5+1.551)[/tex]

                                       [tex]-5y= -3.449[/tex]

                                            [tex]y =\frac{3.449}{5}[/tex]

                                            y = 0.6898

Step:3

          Check for solution,

                                [tex]-7x+2y=5[/tex]..........................(1)

    [tex](-7)(-0.517)+(2)(0.6898)=5[/tex]

                        [tex]3.619+1.3796=5[/tex]

                                             5 = 5

Result:

         The solution for given equations [tex]-7x+2y=5[/tex] and [tex]3x-5y=-5[/tex] are x= -0.517 and y = 0.6896.

Answer:

k = 5

Step-by-step explanation:

Step 1:  Cross multiply

k/6 = 15/18

k(18) = 6(15)

18k = 90

Step 2:  Divide both sides by 18

18k / 18 = 90 / 18

k = 5

Answer:  k = 5

Another way to do it is to multiply both sides by 6

k/6 * 6 = 15/18 * 6

k = 90 / 18

k = 5

Answer: 5

Step-by-step explanation: To solve for k in the given proportion, we use the means-extremes property. The product of the extremes, (k)(18), equals the product of the means, (6)(15).

So we have (k)(18) or 18k = (6)(15) or 90.

Now we have the equation 18k = 90.

Dividing both sides by 18, k = 5.

It's a good idea to check the answer in these types of problems so if we plug a 5 back in for k in the original proportion, we have [tex]\frac{(5)}{6}= \frac{15}{18}[/tex] which is a true statement since 15/18 reduces to 5/6.
