Graph f(x) = 2x - 3 on a coordinate plane.
adoni [48]

Answer:

Create a table.

Plug values into the equation to complete the table.

Use the table to plot points on the graph.

Draw lines through the points on your graph.

1. An airline knows that only about 75% of those who make a reservation actually buy a ticket. At this rate, how many reservatio
madam [21]
We have to use proportion to solve this problem.
75% -------------------180
100% ---------------------x
crossmultiply
75*x=100*180
75x=18000           /:75
x=240 - its the answer

We have similar problem here
8%---------------------60$
100% ------------------x
crossmultiply now
8*x=60*100
8x=600        /:8
x=75 - its the answer

The LCD for the fractions 1/3, 3/4, 5/32, and 8/9 is
tresset_1 [31]
What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:

3, 2^2, 2^5, 3^2

Your LCD must include the following factors:  3^2 and 2^5, or 9 and 32.  Multiplying these together results in the correct LCD 9*32=288.

Check:  Is 288 divisible by 3?  Yes.  The quotient is 96.
Is 288 divisible by 4?  Yes.  Is 288 divisible by 32?  Yes.  Is 288 divisible by 9?  Yes.

Use the functions f(x) and g(x) to determine which function has the smallest zero and provide its coordinates.
Veseljchak [2.6K]

Answer:

Function with smallest zero  is:

f(x); (2, 0).

Step-by-step explanation:

f(x):

2x2 − 14x + 20 = 0

x^2 - 7x + 10 = 0

(x - 5)(x - 2) = 0

So the zeroes are (2, 0) and (5, 0)

g(x):

From the table:

when g(x) = 0, x =19 so its zero is (19, 0).
