Answer:
Price of a senior citizen ticket is $4 and price of a student ticket is $15 .
Step-by-step explanation:
Let us assume that the price a senior citizen ticket be x .
Let us assume that the price a student citizen ticket be y .
As given
The school that Jack goes to is selling tickets to a choral performance.
On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.
Equtaions becomes
9x + 8y = 156
As given
The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.
Equations becomes
7x + 9y = 163
Multipy 9x + 8y = 156 by 9 .
81x + 72y = 1404
Multiply 7x + 9y = 163 by 8 .
56x + 72y = 1304
Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .
81x - 56x + 72y - 72y = 1404 - 1304
25x = 100
x = $ 4
Putting value of x in the 56x + 72y = 1304 .
56 × 4 + 72y = 1304
224 + 72y = 1304
72y = 1304 - 224
72y = 1080
y = $15
Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .
The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis ⇒ Last answer
Step-by-step explanation:
Let us revise some transformation
A horizontal compression (or shrinking) is the squeezing of the graph toward the y-axis.
A horizontal stretching is the stretching of the graph away from the y-axis
- If k > 1, the graph of y = f(k•x) is the graph of f(x) horizontally shrunk (or compressed) by dividing each of its x-coordinates by k.
- If 0 < k < 1 (a fraction), the graph of y = f(k•x) is the graph of f(x) horizontally stretched by dividing each of its x-coordinates by k
- If k should be negative, the horizontal stretch or shrink is followed by a reflection across the y-axis
∵ y = √x is a parent function
∵ Its graph transformed to produce the graph of y = √(-2x)
- That means x is multiplied by a factor k, then it is compressed
or stretched horizontally
∵ k = -2
- The factor is -2, where 2 is greater than 1, then it is compressed
horizontally as the first rule above and the negative means
reflected across the y-axis as the third rule above
∴ The graph of the parent function is compressed horizontally and
reflected across the y-axis
The graph of the parent function is horizontally compressed by a factor of 2 and reflected over the y-axis
