Can anybody help me with this? Algebra 1

Marina CMI [18]

Answer:

see below

Step-by-step explanation:

7. f(x) = mx + b; b acts as the vertical shift moving the graph up if b is positive and down if b is negative.

f(x) = x-2 has shifted the graph of f(x) down 2 units.

g(x) = x + 7 has shifted the graph up 7 units.

If f(x) is changed to g(x) the vertical shift has gone from -2 to + 7 or (7-(-2) = 9 units up

8. f(x) = mx stretches the graph by a factor of m if m > 0 and compresses the graph by a factor of m if 0<m<1

f(x) = 3x stretches the graph by a factor of 3.

g(x) = 1/4x compresses the graph by a factor of 1/4

At the movie theatre, child admission is $5.10 and adult admission is $9.00 .

sveticcg [70]

Answer:

$5.10 X +9.00 Y = 831.60$

We also know that for Wedneday we have two times tickets for adults compared to child so we have

$Y =2x$

And using this condition we have:

$5.10 X + 18 X = 831.60$

And solving for X we got:

$X= \frac{831.60}{23.1}=36$

So then the number of tickets sold for child are 36

Step-by-step explanation:

For this problem we can set upt the following notation

X = number of tickets for child

Y= number of tickets for adults

And we know that the total revenue for Wednesday was 831.60. So then we can set up the following equation for the total revenue

$5.10 X +9.00 Y = 831.60$

We also know that for Wedneday we have two times tickets for adults compared to child so we have

$Y =2x$

And using this condition we have:

$5.10 X + 18 X = 831.60$

And solving for X we got:

$X= \frac{831.60}{23.1}=36$

So then the number of tickets sold for child are 36

Find the x- and y-intercepts for the graph of the equation: 9x-6y=3

erik [133]

9x-6y=3
x -intercepts y = 0, 9x = 3 then x = 1/3
y -intercepts x = 0, -6y = 3 then y = -1/2

answer
x -intercepts (1/3, 0)
y -intercepts (0, -1/2)
