Answer 1

Answer:

7k+7

Step-by-step explanation:

Distribute the 7 -

7(k+1)

7 * k = 7k

7*1 = 7

so 7k + 1

Insert 3 instead of x, so it reads -

[tex]5[/tex][tex](3)^{2}[/tex] - 4

[tex]3^{2} = 9[/tex]

9 * 5 = 45

45 - 4 = 41

Which equation represents the data in this function table?

A. y = x + 4
B. y = x - 4
C. y = 4x
D. x = y + 3

Answers

Answer:

Step-by-step explanation:

If you put the x value of the table and use it in each equation, only one gives the y output on the table.

y=x + 4

5=1 + 4

6=2+4

7=3+4

8=4+4

9=5+4

The correct option is A) y=x+4

What are linear equations?

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here option A as y=x+4 now lets verify this option

if x=1 then y = 1+4

= 5

Again if x=2 then y =2+4

Similarly it can be clearly observed that all the values of y are 4 greater than the input of x given in the table.

Hence, option A is the correct answer.

Alright, so a circle is 360 degrees. We know there's an arc of 90 and an angle extending from the radius being 125.

Since the given angle extending from the radius is at the radius, there will also be a 125 degree arc at the circumference of the circle there.

With this, do:

360-90-125 = 145

to get the amount of arc in the unknown area.

Still though, we need to find the x value, so get the unknown value and set it equal to 145.

16x + 1 = 145

16x + 1-1 = 145-1

16x=145

x = 9.0625 or 9 1/16

Hope that helps.

Step-by-step explanation:

-7, -3, 1, 5 what is the explicit formula

Answers

Answer:

f(x)=4x-11

Step-by-step explanation:

This is a linear sequence, so we have to find our common difference, or slope, by finding the difference between any term and its previous term. We should do this a couple of times to make sure it's consistent. In this case, our slope is 4 and our first term is -7. We can do our equation in slope intercept (y=mx+b) form. However, to do this, we have to find the '0'th' term, or the term where x=0, a.k.a. the y-intercept. Our 1st term where x-1 is -7, and since our common difference is 4, we subtract 4 from negative 7 to get a y-intercept of -11. Our equation is now y=4x-11. To make this an explicit formula, we convert into f(x) form to get a formula of f(x)=4x-11.

Answers

Answer:

D. The mean would decrease as there is less variability in the data.

Step-by-step explanation:

So, let’s find the mean with all of those numbers. First of all we should order them from least to greatest.

11.9, 12.0, 12.3, 12.3, 13.5, 16.0

We add them all up, and get 78! Once we get this total, we must divide it by how many numbers there are! There are six numbers, so 78/6.

78/6 is equal to 13. So the mean for all those numbers is 13.

Now let’s find the mean if we cross out the greatest and least numbers, the greatest number is 16.0, and the least number Is 11.9.

So, our new data set is:

12.0, 12.3, 12.3, 13.5

Add those all up to get 50.1

Divide the total by the numbers we got left, which is 4!

50.1/4 is equal to 12.525.

So the mean of our new data set is 12.525!

So that’s how I got the answer, have a nice day! Please tell me if I’m wrong!

Step-by-step explanation:

Total cost(gg) = $65 + ($5/mo)(gg) = $85

Ths reduced to $85 - $65 = ($5/mo)(gg), which returns gg = 4

The correct answer is an inequality: gg ≤ 4
