Answer:

A, B, D and F.

Step-by-step explanation:

Rin spends $20 every week on drum lessons.

If:

d = total amount of dollars Rin spends

w = number of weeks

Then: d=20w

w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:

(A)The independent variable causes a change in the dependent variable.

(B)The equation is d = 20w.

From the equation: d=20w

When w=1, d=$20

When w=2, d=$40

When w=3, d=$60

When w=4, d=$80

This tallys with the values in Option F.

Therefore:

(D)As the number of weeks increases, the total dollars Rin spends increases.

The correct options are: A, B, D and F.

What is the slope??????

nikitadnepr [17]

Answer: The slope is 1/4.

Step-by-step explanation:

To find the slope, find two points on the line and find the difference in their y coordinates and divide it by the difference in their x coordinates .

(0,20) and (40,30)

Difference in y: 30 - 20 = 10

Difference in x: 40 - 0 = 40

Slope: 10/ 40 = 1/4

Find the equation of the linear function 'g' going through (20,5) and (-5,-8). Use 'u' for your input variable.

frosja888 [35]

Answer:

See below

Step-by-step explanation:

Use the slope-intercept form, which will be in this case:

g(u) = mu + b, where m is the slope, b is the y- intercept

Find the slope:

$m=(y_2-y_1)/(x_2-x_1)$
$m=(-8-5)/(-5-20)=(-13)/(-25)=13/25$

Find the value of the y-intercept:

$5=1/25*20+b$
$b=5-4/5=21/5$

The equation is:

$g(u)=\frac{13}{25} u+\frac{21}{5}$

Rounded to hundred how can I round to hundred

Gwar [14]

If you are talking about any number then.....
imagine a mountain, any number less than 5 is only the left and any number greater than 5 is on the right

Here, for example, let's try 13

look at 13 on the pyramid .... since it's not a the top of the mountain so it falls back down to 10... it rounds down to 10
Now let's try 18 ...hmmm.... 18 is not at the top either so it falls as well. It falls down to 20 it rounds up to 20

how about 15 u might be asking...it is at the top...15 is a little different ...make sure no one is looking and push it off the right side and falls to 20. Also rounding up to 20
