9x + 26 + 7x - 17 = 2x + (-3x) + 5x =
16x + 9 = 2x - 3x + 5x =
16x + 9 = 4x
9 = 4x - 16x
9 = - 12x
-9/12 = x
- 3/4 = x
Answer:
Step-by-step explanation:
Second option correct
Answer:
It usually works to follow instructions.
Step-by-step explanation:
<h3>Exercise 1.</h3>
Apparently, you are to plot the given points on the graph. The axes are clearly labeled, so it is a matter of identifying the appropriate grid crossing and putting a dot there. See the first attachment.
<h3>Exercise 2.</h3>
You can read the desired values from the graph you just plotted (as the instructions say), or you can simply read them from the table.
- 2 million
- 5 million
- 9 million
<h3>1. </h3>
See the red line and points in the second attachment. Usually, values on the axes of a graph will <em>increase</em> up and to the right.
<h3>2.</h3>
See the purple line and points in the second attachment.
<h3>3.</h3>
The point of intersection is (price, quantity) = (40, 350).
The answer is 3.40 since you rounded to the hundredths place and not the tenths.
Answer:
5040 ways
Step-by-step explanation:
That is 7 books.
So the number of ways is factorial 7 , written 7!.
= 7*6*5*4*3*2*1
= 5040 ways
