Answer:

 5y = -2x + 31

Step-by-step explanation:

Given equation:

      y = [tex]\frac{5}{2} x + 3[/tex]

Coordinate  = (-7,9)

Unknown:

Equation of the line perpendicular  = ?

Solution:

The slope - intercept format of a line is given as;

      y = mx + c

where y and x are the coordinates

           m is the slope

           c is the y-intercept

y = [tex]\frac{5}{2} x + 3[/tex]

 From the given equation; slope is [tex]\frac{5}{2}[/tex]

A line perpendicular will have a slope that is negative and the inverse of this;

      slope of perpendicular line  = [tex]-\frac{2}{5}[/tex]

Since y= 9 and x = -7;

  So;

            9 = [tex]\frac{-2}{5} x (-7)[/tex] + C

            9 = [tex]\frac{14}{5}[/tex] + C

           C  = 9 - [tex]\frac{14}{5}[/tex]   = [tex]\frac{31}{5}[/tex]

Now,

       y  =  [tex]-\frac{2}{5}[/tex]x +  [tex]\frac{31}{5}[/tex]

mulitply through by 5;

     5y = -2x + 31

Answer:

8000

Step-by-step explanation:

8000

10^6-2*7.2/9

72000/9 = 8000

Answer:

No solutions

Step-by-step explanation:

First things first we need to get rid of the variables so we subtract -12x from one side to the other.

Now we have 1= -10

In this case, 1 is not equal to -10 so we get no solutions!

(Side note: if they were the same like 3=3 that would be all solutions.)

Answer:

6x^3 + 24x^2

Step-by-step explanation:

We need to find (f * g)(x)

If we distribute the "x" here, we should get f(x) * g(x), which is what we have to solve for

f(x) * g(x) = 6x(x^2 + 4x)

= 6x^3 + 6x(4x)

= 6x^3 + 24x^2

This is the simplest expression you can get

The value of measure ∠PQR is,

⇒ ∠PQR = 133°

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

In the given figure,

⇒ ∠PQR = (3x - 5)°

⇒ ∠ RQS = (x + 1)°

Now, By the figure we can conclude,

⇒ ∠PQR + ∠ RQS = 180°

Substitute the given values, we get;

⇒ (3x - 5) + (x + 1) = 180

⇒ 4x - 4 = 180

⇒ 4x = 180 + 4

⇒ 4x = 184

⇒ x = 184/4

⇒ x = 46

Thus, The value of measure ∠PQR is,

⇒ ∠PQR = (3x - 5)°

⇒ ∠PQR = (3 × 46 - 5)°

⇒ ∠PQR = (138 - 5)°

⇒ ∠PQR = 133°

The complete question is shown in figure.

Answer: m = 3/2, b = -5

Step-by-step explanation:

When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.

Answer:

4*10^-6

Step-by-step explanation:

Answer:

A (1,-2) B(10,1) C(6,2)

Step-by-step explanation:

You add 4 to the x value and subtract 3 from the y value to get the answer.

The coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).

To represent the given translation, we need to add the same constant amount to the x-coordinate of each vertex and subtract the same constant amount from the y-coordinate of each vertex.

Let's call the constants of translation "a" and "b", respectively. Then the rule P(x, y) → P'(x + a, y - b) represents the translation of a figure where P is any point in the original figure and P' is the corresponding point in the translated figure.

To find the coordinates after the translation, we need to apply the translation rule to each vertex of the triangle.

For vertex A(-3, 1), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of A': (-3 + 4, 1 - 3) = (1, -2).

For vertex B(6, 4), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of B': (6 + 4, 4 - 3) = (10, 1).

For vertex C(2, 5), we add 4 to the x-coordinate and subtract 3 from the y-coordinate, giving us the new coordinates of C': (2 + 4, 5 - 3) = (6, 2).

Therefore, the coordinates of the vertices after the translation are A'(1, -2), B'(10, 1), and C'(6, 2).

[tex]f^{12}[/tex] × [tex]f^{12}[/tex] = [tex]f^{(12+12)}[/tex] = [tex]f^{24}[/tex]

Answer:

B

Step-by-step explanation:

the way i work it out is if you take the product and power it to the third you can easily find out which answer is correct. another way, if you don't have a calculator is to look at the last digit in the number in the square root sign.

For example, 3 square root 64 equals 8. you would look at the 4 and try to find 3 numbers that end in 4 OR is divisible three times by the number. 64 is exactly divisible by 4 only 3 times so you know that it can't be 8.

Answer:

B. 4.5c + 4 = 24

Step-by-step explanation:

T = cx + py  is the equation you are given.

T = 24 because it is the total amount of money you can spend.

x = 4.5 because each phone case costs 4.50 dollars

p = 2 because you bought 2 pop sockets.

y = 2 because each pop socket costs 2 dollars.

There is no c because you don't know the number of phone cases you bought.

Now, we have to substitute the values into the equation:

24 = 4.5x + 2(2)

24 = 4.5x + 4

4.5x + 4 = 24       <--- This is your answer

Given parameters:

Coordinates of the two points = (-5, 6) and (8,-4)

Unknown:

Distance between the two points.

To find the distance between two points, use the expression below;

  Distance ²  = (x₂ - x₁)² + (y₂ - y₁)²

where;

(-5, 6) and (8,-4)

         x₂ = 8 , x₁ = -5 , y₂ = -4 and y₁ = 6

Input the parameters and solve;

 Distance²  =  (8-(-5))²  +  (-4 - (6))²

                    = 169 + 100

                    = 269

Distance = [tex]\sqrt269}[/tex]   = 16.4

Answer:

- 44 feets

Step-by-step explanation:

Given the model:

h(t) = -15t2 + 25t + 6

Average height of object from 1 - 4 seconds

At :

t = 1

h(1) = -15(1)^2 + 25(1) + 6 = 16 feets

t = 2

h(2) = -15(2)^2 + 25(2) + 6 = - 4 feets

t = 3

h(3) = -15(3)^2 + 25(3) + 6 = - 54 feets

t = 4

h(4) = -15(4)^2 + 25(4) + 6 = -134 feets

Average height:

(16 + (-4) + (-54) + (-134)) / 4 feets = (- 176 / 4) feets

= - 44 feets
