What is the average rate of change of the line?

Answers

Answer:

- 12

Step-by-step explanation:

The slope of the line is a measure of the average rate of change

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 12(x + 4) ← is in point- slope form

with slope m = - 12 ← average rate of change

Well first you have to find the rule which is +3.
I found that because 1(+3) is 4, 4(+3) is 7, and 7(+3) is 10.

So, i’m not sure if you meant the “9th term” but you can just keep adding three to the equation, to get to whatever term you need.

4y - 2y = 6
2y = 6
y = 3

As y is 3

Answer:

X = 70 degrees

Step-by-step explanation:

The way to figure this out is by taking the angle of the 30 degrees and applying it to the opposite side of its self then just add it to the 80 degrees which will equal 110 and since a straight line has 180 degrees just subtract 180 by 110 and that will be the value of x because the lines are parallel and the line that goes through both lines will always have the same angle.

Need an answer fast will mark Brainliest!

Answers

Answer:

x=.3 or 3/10

Step-by-step explanation:

to solve for x, we need to separate it

so, we add 13 to the left side

40-11x=x

then add 11x to the right side so we have different coefficients on each side to solve for x

40=12x

then we divide 40/12 to get what x equals

we get

x= 0.3 or 3/10

hope this helped!

Answer:

x=10/3

Step-by-step explanation:

27 - 11x = x - 13

27+13=x+11x

40=12x

x=40/12

x=10/3

Answer:

The length is 42 inches and the width is 14 inches

Step-by-step explanation:

You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.

You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.

Then you subtract 2y from both sides to get the unit value of y.

Y is equal to 18.

Then you can plug 18 into the y's to get

2(18)+6 which is 36+6 = 42

18-4   = 14

There you go.

The length is the longer side which is 42 inches and the width is 14 inches

Please help!!! How many pages can be read in 45 minutes? Answer with a decimal point rounded to the nearest tenth if necessary.

Answers

Answer:

157.5 pages

Step-by-step explanation:

First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:

2m = 7

---      ---      <---- Here we divide both sides of the equal sign by 2

2        2

m = 3.5 <---- we read 3.5 pages per minute

45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.

B is the correct answers

Step-by-step explanation:

Issun Sengeki... Messatsu!

In my opinion, I'd say A and C aren't functions, but B is a function.

The reason being is because every "X" value has a "Y" value. For those that don't have exactly 1 "Y" value aren't functions.

A. has more "Y" values than "X" values, so that proves not to be a function.B. Has "X" values that are exactly appointed to a "Y" value.C. Has one "X" value that's missing, and a "Y" value that doesn't exist.
