Answer:

$5,250

Step-by-step explanation:

2/7x - [4/5(2/7x)] = 300

2/7x - 8/35x = 300

10/35x = 8/35x = 300

2/35x = 300

2x = 10500

x = 5250

5.a) Steve - 60=5×12

= <u>5×3×2×2</u>

5.b) Ian - 60=6×10

= <u>3×2×5×2.</u>

<u>Discussion</u> - The prime factors reduce to the same numbers in both Steve's and Ian's case.

5.c) Case 1 of 48 = 6×8

= <u>3×2×2×2×2.</u>

Case 2 of 48 = 12×4

What is the equation of the graph below?
wlad13 [49]

<u>Answer:</u>

<u>y=cos(x+\pi )</u>

<u>Step-by-step explanation:</u>

From the graph, we can see that y = -1 when x  = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = cos(x + pi/2) = cos(0 + pi/2) = 0

2. y = cos(x+2pi) = cos(0+2pi) = 1

3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5

4. y = cos(x+pi) = cos(0+pi) = -1


Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.
