pls help me with question 3

Answer:

y=6x+10a

Step-by-step explanation:

let the number of children be x

and the number of adults be a

let the total price be y

given that children tickets are $6 each

also, an adult ticket is $10

x+a=14-------1

y=6x+10a----2

Therefore the expression for the total price can be expressed as

 y=6x+10a

Answer:

b = 15

Step-by-step explanation:

Answer:

b = 15

Step-by-step explanation:

Solve for b:

4.8/ 1 7/9 = 1.2b/6 2/3

Cross multiply:

6 2/3 * 4.8 = 1.2b * 1 7/9

6 * 3 + 2/3 * 4.8 = 1.2b * 9 + 7/9

20/3 * 48/10 = 12b/10 * 16/9

20 * 4 = b * 16/3

5 = b * 1/3

b = 5 * 3

b = 15

Step-by-step explanation:

-72/80 = -36/40 = -18/20 = -9/10

Answer:

Step-by-step explanation:

4x2 - 8x -12 = 0

divide through by 4

x2 - 2x - 3 = 0

x2 - 3x + x - 3 = 0

(x2 - 3x) + (x - 3) = 0

x(x - 3) + 1(x - 3) = 0

(x + 1) (x - 3) = 0

x + 1 = 0 and x - 3 = 0

x = -1 and x = 3

Answer:

B IS THE ANSWER

Step-by-step explanat

(22x2 -  8x) -  12  = 0

  4x2 - 8x - 12  =   4 • (x2 - 2x - 3)

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3  

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   -2 .

     -3    +    1    =    -2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  1  

                    x2 - 3x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-3)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-3)

Step-5 : Add up the four terms of step 4 :

                   (x+1)  •  (x-3)

            Which is the desired factorization

4 • (x + 1) • (x - 3)  = 0

A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately  

Any solution of term = 0 solves product = 0 as well.

  Solve  :    x+1 = 0

Subtract  1  from both sides of the equation :  

                     x = -1

   Solve  :    x-3 = 0  

Add  3  to both sides of the equation :  

                     x = 3

Answer:

The only zero of [tex]F^{-1}(x)[/tex] is [tex]3[/tex].

Step-by-step explanation:

The function [tex]F^{-1}[/tex] is the inverse of function [tex]F[/tex].

For a given [tex]x[/tex] and a given [tex]y[/tex], [tex]F^{-1}(y) = x[/tex] if and only if [tex]F(x) = y[/tex].

Let [tex]y[/tex] be a zero of [tex]F^{-1}(y)[/tex]. That is, [tex]F^{-1}(y) = 0[/tex].

By the reasoning above, since [tex]x = 0[/tex] and this particular [tex]y[/tex] satisfy [tex]F^{-1}(y) = x[/tex], it must be true that [tex]F(x) = y[/tex] for the same [tex]x = 0\![/tex] and [tex]y\![/tex].

Since [tex]x = 0[/tex] and [tex]F(x) = x + 3[/tex], [tex]F(0) = 3[/tex]. Therefore, [tex]y = F(0) = 3[/tex] since [tex]y = F(x)[/tex].

Thus, the zero of [tex]F^{-1}(y)[/tex] would be [tex]y = 3[/tex].

Answer:

y = -x

Step-by-step explanation:

Slope-intercept form looks like this: y = mx + b, with m being the slope or rate of change and b being the y-intercept. We already know the rate of change, so we can put -1 as m: y = -1x + b. To find our y-intercept, we can plug the point (3, -3) into the equation and solve for b:

-3 = -1(3) + b

-3 = -3 + b

b = 0

So we have y = -1x + 0. This can be simplified to y = -x.

Answer:

  -19/7

Step-by-step explanation:

If the variation is direct, any multiplier of the m-value will also multiply the f-value.

 old value × 1/7 = new value

 m: 14 × 1/7 = 2

 f: -19 × 1/7 = -19/7

The new value of f is -19/7.

Answer:

its graph c

Step-by-step explanation:

The two equations that can be used to represent his number of visits with his total cost will be 20 + 2x and 5x.

Let the number of visits be represented by x.

Since Keith can get a $20 membership card and pay $2 for every visit, or he can go any time and just pay $5 for each visit, then the equation to represent the information will be:

20 + (2 × x) = (5 × x)

20 + 2x = 5x

Therefore, the equations will be 20 + 2x and 5x.

Answer:

48 meters

Step-by-step explanation:

The drawing will be twice as large in all dimensions.  The perimeter will be the same, 48 meters.  The new scale for the new drawing should reflect that 1 unit on the drawing = x meters.  In both cases the perimeter will be the same.  The drawing size and scale factors are different.  When you get to a scale of 1:1, you'll have an actual drawing with a perimeter of 48 meters.

Answer:

  1. x = {6, 16}

  2. (x -8)² +(y +7/3)² = 64

Step-by-step explanation:

1. The distance formula is useful for this.

  d² = (x2 -x1)² +(y2 -y1)²

  13² = (x -11)² +(-5 -7)² . . . . . . . . fill in the given point coordinates

  169 -144 = (x -11)² = 25 . . . . . . subtract 144

  x -11 = ±5 . . . . . . . . . . . . . . . . . take the square root

  x = 11 ±5 = {6, 16} . . . . . . . . . . add 11

The values of x that make the points 13 units apart are 6, 16.

2. The standard form equation of a circle is ...

  (x -h)² +(y -k)² = r² . . . . . . circle centered at (h, k) with radius r

In order for the circle to be tangent to the y-axis, the radius must be equal to the distance the center is from the y-axis: the x-coordinate of the center point. That is, r = 8.

  (x -8)² +(y +7/3)² = 64

The rate of change of a graph, is the slope of the graph.

The rate of change of the graph is 4.5

The points on the graph are:

[tex]\mathbf{(x,y) = (2,9) (4,18)}[/tex]

So, the slope (m) is calculated as:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

This gives

[tex]\mathbf{m = \frac{18 - 9}{4-2}}[/tex]

[tex]\mathbf{m = \frac{9}{2}}[/tex]

[tex]\mathbf{m = 4.5}[/tex]

Hence, the rate of change of the graph is 4.5
