Answer:  y = -4x + 6

Step-by-step explanation:

supposing m1 is the gradient of the line  for whose equation  we want to find

m1  * m2 =-1  for perpendicular lines

if m1 = 1/4

meaning m2 = -4

m2= -4 at point (2,-2)

we can get value of constant  c

y = mx =c

-2 = (-4)(2) +c

c = 6

substituting c and m2 in gen eqn of line : y =mx +c

y = -4x + 6

Step-by-step explanation:

f(x) , when x = 0 → f(x) = 6

So, f(0) = 6

f(x) , when x = 5 → f(x) = 7

So, f(5) = 7

f(x) , when x = 6 → f(x) = -3

So, f(6) = -3

f(x) , when x = 8 → f(x) = 10

So, f(8) = 10

The answer is A.

Step-by-step explanation:

The sum of the polynomials in the equation is 3x² - 2x - 3

Step-by-step explanation:

(3 - 4x + 8x²) + (-6 + 2x - 5x²)

Distribute the positive sign to (-6 + 2x - 5x²). So all of these terms will stay the same and maintain their original signs.

3 - 4x + 8x² - 6 + 2x - 5x²

Combine like terms.

- 3 - 2x + 3x²

Now put the equation in standard form. This means that the exponential numbers will be ordered in descending order.

3x² - 2x - 3

[tex] \bf \implies \: {3x}^{2} - 2x - 3 \\[/tex]

Step-by-step explanation:

The number of minutes of each medium should be used to minimize costs if television costs $900/minute and radio costs $200/minute is 45 minutes and 3.33 minutes respectively.

x ≥ 0

y ≥ 0

x + y ≤ 80

0.09x + 0.006y ≤ 2.16

From (1)

x ≤ 80 - y

0.09x + 0.006y ≤ 2.16

0.09(80 - y) + 0.006y ≤ 2.16

7.2 - 0.09y + 0.006y ≤ 2.16

7.2 - 0.084y ≤ 2.16

-0.084y ≤ 2.16 - 7.2

-0.084y ≤ -5.04

y ≤ -5.04 / -0.084

y ≤ 60

x + y ≤ 80

x + 60 ≤ 80

x ≤ 80 - 60

x ≤ 20

The number of minutes of each medium should be used to minimize costs if television costs $900/minute and radio costs $200/minute is

Television = $900 / 20

The co-ordinates of the y-intercept is (0,-9) .

Y-intercept is the point on the graph where the graph passes over the y-axis.

To calculate the y-intercept we have to graphically represent the curve and pick out the points where the graph crosses over the x-axis.

For a graph with an equation in the form y = f(x) , y intercept can be calculated by substituting the value of x as 0 in the equation.

In the graphical representation we can see that the graph passes through  (- 8, 3) and (- 3, - 4.5).

Therefore the slope of the line passing through these points is given by:

[tex]m=\frac{-4.5-3}{-3-(-8)} \\\\m=\frac{-7.5}{5} \\\\m=-\frac{3}{2}[/tex]

Now the equation of the line is given by :

[tex]y-3 =- \frac{3}{2} (x-(-8))[/tex]

[tex]y-3 =- \frac{3}{2} x - 12[/tex]

[tex]y=- \frac{3}{2} x - 9[/tex]

Therefore at x = 0 , the value of y is -9.

So the y-intercept is given by the point (0,-9) .

The coordinates of the y-intercept are ( 0 , 9 / 5 ) .

Finding equation of line :

( y - 3 ) / ( x + 8 ) = ( 3 + 4.5 ) / ( - 8 + 3 )

( y - 3 ) / ( x + 8 ) = ( 7.5 ) / ( - 5 )

- 5 y + 15 = 7.5 x + 6

- 5 y - 7.5 x + 9 = 0

Equation of line : 5 y + 7.5 x - 9 = 0

Writing equation in Slope - Intercept form

y = m x + c

y = [ ( - 7.5 x ) / ( 5 ) ] + [ 9 / 5 ]

Hence , y - intercept = 9 / 5 .

B ∪ A is the relationship between Set A and Set B.

We have two sets A and B.

We have to determine the relationship between set A and set B if A intersects B = B.

A set is a collection of elements, numbers or objects, represented within the curly brackets { }.

According to the question -

A ∩ B = B.

This means that the intersection of set A and set B is equal to B. This means common elements in both the set are same as the elements of set B. This can only happen when -

B ∪ A → B is the subset of A.

After calculating the volume of these two rectangular prisms , we have come to conclude that the total volume of two rectangular prisms is 372 in³.

A rectangular prism is a three-dimensional shape with six faces, all of which are rectangles (top, bottom, and lateral faces) and all pairs of opposite faces are congruent.

A rectangular prism, like all three-dimensional shapes, has volume and surface area. A cuboid is simply another name for a rectangular prism.

A rectangular prism is basically a rectangle,

so the volume = l × b × h

Volume of 1st rectangular prisms = 9 × 6 × 3  

                                                       = 162 in³

Volume of 2nd rectangular prisms = 10 × 7 × 3  

                                                          = 210 in³

Total volume = 162 + 210

                      = 372 in³

Answer:

15.  x-intercept = (-4, 0)

      y-intercept = (0, 2.5)

16.  A. An infinite number of solutions.

Step-by-step explanation:

The x-intercepts are where the line crosses the x-axis, i.e. when y = 0.

The y-intercepts are where the line crosses the y-axis, i.e. when x = 0.

Given equation:

[tex]5x-8y=-20[/tex]

Substitute y = 0 into the given equation to find the x-intercept:

[tex]\begin{aligned}y=0 \implies 5x-8(0) &=-20\\5x & = -20\\x & = \dfrac{-20}{5}\\x & = -4\end{aligned}[/tex]

Therefore, the x-intercept is (-4, 0).

Substitute x = 0 into the given equation to find the y-intercept:

[tex]\begin{aligned}x=0 \implies 5(0)-8y &=-20\\-8y & = -20\\y & = \dfrac{-20}{-8}\\y & =2.5\end{aligned}[/tex]

Therefore, the y-intercept is (0, 2.5).

Given system of equations:

[tex]\begin{cases}3x-2y=14\\6x=4y+28\end{cases}[/tex]

Multiply the first equation by 2:

[tex]\implies 2(3x-2y)=2(14)[/tex]

[tex]\implies 6x-4y=28[/tex]

Add 4y to both sides:

[tex]\implies 6x-4y+4y=4y+28[/tex]

[tex]\implies 6x=4y+28[/tex]

Therefore, the two equations are the same.  

A system of linear equations has an infinite number of solutions when the graphs are the exact same line.
