Step-by-step explanation:

If you replace each x with -3 and each y with 2 you get:

1) 2<-4*(-3)

2<12

True

2) -3+8*2>7

Answer:

3600 tickets were sold for the musical performance.

Step-by-step explanation:

Given that:

Number of people seated for musical performance = 108

Percent to people to arrive yet = 97%

It means that the people who have already come are 3%.

Let,

x be the number of tickets sold.

3% of x = 108

$\frac{3}{100}x=108\\$

0.03x = 108

Dividing both sides by 0.03

$\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600$

Hence,

3600 tickets were sold for the musical performance.

-Find the y-intercept of the line with the equation 2x+y=5.

AlekseyPX

Answer:

E. 5

Step-by-step explanation:

Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

2x + y = 5

y = -2x+5

M, the slope, is -2

<u>5, b, is the y-intercept</u>

See attached graph.

B
This is because the segement IK contains 2 parts of the total 5 parts in which the segment IJ has been divided. Therefore, multiplying by 2/5 will help Douglas find the x-coordinate of K.
