Answer:

1. x=2

2. x= 0.33

Step-by-step explanation:

1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so

-5 -5

then you have 4x=8. you divide by 4 on both sides

4. 4

so then you get x=2

2.So same here find what 3 to the power of 2 is =9

New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so

9x+4x = 13x

new equation. 4x-1=13x-4

next subtract 4x on both sides

13x-4x=9x

new equation. -1=9x-4

next add 4 to both sides

-1+4= 3

new equation. 3=9x

so then divide 9 on both sides

3÷9= 0.33

x= 0.33

Hope this made sense and helps

What is the period of the graph of y=2 cos (pie/3 x ) +3<br> A.2<br> B.3/pie<br> C.6<br> D.pie/3

Tatiana [17]

Equate what is inside cosine with $2\pi$ , base period and solve for x,

$2\pi=\frac{\pi}{3}x$

$6\pi=\pi x$

$\boxed{x=6}$

Hope this helps :)

Look at the data in the table.

11111nata11111 [884]

Given table

______

x y

______

2.4 9

7.2 28

7 24

8.3 35

3.1 9

7.2 30

9 32

_________

So, the coordinates on the graph (2.4, 9), (7.2, 28), (7, 24), (8.3, 35), (3.1 , 9), ( 7.2, 30), (9, 32).

The first graph represents the line of best fit.

The definition of line of best fit " A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.".

<h3>Note: Most of the points should be as closer as possible to the drawn line. </h3>
