The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the

PIT_PIT [208]

Tickets cost $0.75t. Kendall bought 18 tickets, so you can substitute 18 for the variable t because it stands for the amount of tickets bought.

$0.75(18) = $13.50

Kendall spent a total of $33.50, so that means she spent $13.50 on tickets and the rest she spent on admission, so 33.50 - 13.50 = 20; she spent $20.00 on admission.

(a) The variable are t, amount of tickets bought, and a, admission price.

(b) The linear equation for anyone who only pays for festival admission and rides would look like: 0.75t + a.

(c) I made the linear equation 0.75t + a because first you would have to pay the admission fee (a), and then you would pay for EACH ticket (t). So t would be the changing variable depending on how many tickets a person would choose to buy.

Write the equation of the function that can be modeled by this table?

Alika [10]

Answer:

y = 3x + 5

Step-by-step explanation:

y = mx + b (slope-intercept form)

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

Slope m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

y - $y_{1}$ = m( x - $x_{1}$ ) (point-slope form of linear equation)

Help me with my problem

katovenus [111]

It's A. When you reduce between the x exponents in the original you get an xcubed on top. In A, when you reduce between the x exponents you get xcubed on bottom and they cancel each other out.

Please help me with 7 and 9 I’m really confused and I really need help!!

Margarita [4]

Answer:

7) K'(1, 1), N'(4, 0), Q'(4, 4)

9) F'(4, 2), W'(4, 5), K'(3, 2)

Step-by-step explanation:

When you are not sure about reflections and rotations, it can be useful to actually draw a graph. The line of reflection is the perpendicular bisector of the segment connecting a point with its image. That is, the image is the same distance from the line on the other side. A point that is on the line of reflection is "invariant," it doesn't move.

7) Reflecting across the x-axis changes the sign of the y-coordinate. That is all. Any point on the x-axis (y=0) is unchanged. The transformation is ...

(x, y) ⇒ (x, -y)

9) Reflecting across a vertical line changes the x-coordinate. The new value of x will be ...

x' = 6 - x

The "6" is double the x-coordinate of the vertical line. The transformation is ...

(x, y) ⇒ (6-x, y)

Derivation of the formula for reflection on x=3

In general if M is the midpoint of a point (A) and its reflection (A'), then we have ...

M = (A +A')/2

2M = A + A'

2M -A = A'

When a point is reflected across a vertical line, all of the y-coordinate values remain unchanged. So, for A=(x, y) and M=(3, y), we have ...

A' = 2(3, y) -(x, y) = (6-x, 2y-y)

A' = (6 -x, y)

So, the reflection transformation across the line x = 3 is ...

(x, y) ⇒ (6-x, y)
