I need to know how to solve for question number 4 please?

Answer:It's an arithmetic sequence with a common difference, d, = 4

A1 = 8

A2 = 8+4 = 12

A3 = 12+4 = 16   = 8+4(3-1) = 8+4(2) = 8+8

AN = A1 + d(N-1)

AN = 8 +4(N-1)  =  the Nth term in the sequence

Answer:

Let P(t) = population t years after 2010

           = 45230e0.02t

Population in 2030 = P(20)

                           = 45230e0.4≈ 6747

Step-by-step explanation:

slope intercept form y=mx+b

you just need to move the letters and numbers around to match this.

-4x-3y=-18

add 4x to both sides of the equal sign

-3y =4x-18

divide by negative 3 on both sides

y = -4/3x + 6

21. -2x+3y=21

add 2x to both sides

3y = 2x + 21

divide by 3 on both sides

y = 2/3x +7

Step-by-step explanation:

its very easy pls give brainliest

Answer:

2

Step-by-step explanation:

Slope=Rise/Run

What does that mean? It means that the slope is equal to the change in y over the change in x.

It can be defined as m=(y1-y2)/(x1-x2)

Let's pick two random coordinates.

Say...

(30,10) and (40,30).

x1=30

x2=40

y1=10

y2=30

So when we plug those in, we get

m= (10-30)/(30-40)

which simplifies to (-20)/(-10)

which simplifies to 2.

Answer:

x = 6

Step-by-step explanation:

All angles of a triangle equal 180

180 - 70 - 60 = 50

8x+2 = 50

x = 6

Answer:

x = 6

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

70 + 60 + 8x + 2 = 180 , collect like terms

132 + 8x = 180 ( subtract 132 from both sides )

8x = 48 ( divide both sides by 8 )

x = 6

Answer:

On a coordinate plane, a vertical line goes through x = 3.

I haven't looked at the other choices, but clearly this is a function

Answer:

will find at bottom

Step-by-step explanation:

A relation is a function of x if each value of x in the domain corresponds to exactly one value of y in the range. In other words, there should be no repeated values of x with different values of y.

Let's analyze each of the given tables to determine which one represents a function of x:

1. Table 1: In this table, we have x values of -1, 2, 2, and 3. Notice that x = 2 appears twice with different y values. This violates the definition of a function, so Table 1 is not a function of x.

2. Table 2: This table has x values of -8, -8, 1, and 1. Similar to the previous table, x = -8 and x = 1 appear twice with different y values. Therefore, Table 2 is not a function of x.

3. Table 3: In this table, all the x values are the same, which is -5. However, the corresponding y values are different (-9, 7, -9, and 2). Since each x value has a unique y value, Table 3 represents a function of x.

4. Table 4: This table consists of x values of -3, -2, 4, and 7. Each x value corresponds to a unique y value (-1, 5, 0, and -1). Therefore, Table 4 also represents a function of x.

To summarize, the relations that are functions of x are Table 3 and Table 4.

Answer:

Using a calculator, if you typed in 517 divided by 7, you'd get 73.8571. You could also express 517/7 as a mixed fraction: 73 6/7.

Answer:

x = 4, y = -9/2 (-4.5)

Step-by-step explanation:

Using the second equation, we can divide both sides by -2 and get

y = 9/-2

y = -9/2

Then, we plug this y value into the first equation and get:

x + 4(-9/2) = -14

Simplify:

x - 18 = -14

x = 4

Answer:

x ≤ -12

Step-by-step explanation:

to solve for 'x', since it is getting multiplied by 1/4, you must multiply it by the inverse which is 4

whatever gets multiplied to one side of the inequality must also get multiplied to the other side

you will get:

x ≤ -12

Answer:

Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.

Answer:

if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.

We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.

Then draw a vertical line for your stem hopefully it is on lined paper.

single digits 1-9 go right side.

tenths get split keeping digits rights side

hundred units get split keeping tenth and single digits right side

and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.

Larger numbers that have 3 digits are more than double digits I've called 100th units

Numbers lower than 9 will be on rights side on the first line.

1-9  =  0 | 1  2 3 4 5 6 7 8 9

10-19   1 | 0 1 2 3 4 5 6 7 8 9

20-29  2| 0 1 2 3 4 5 6 7 8 9

100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line

We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.

Step-by-step explanation:

Johan - 3/7

Rahul - 4/9

1. Convert fractions

3/7 -> 27/63

4/9 -> 28/63

28/63 > 27/63

Rahul took more by 1/63

Step-by-step explanation:

so (2,1)       (1,3)

     x1,y1      x2,y2

so then it would be

the slope is -1

so the equation is after using your x1 and y1 would be

y-1=-1(x-2)

and after you solve that by using the comunitive property, then it will look like

y-1=-1x+2

then you subtract 1 from the y side and make it

the answer is y=-1x+3

Answer:

The product is 240.

Step-by-step explanation:

The product is always when you multiply numbers together.

Answer:

Using 15 times table, we have 15 times 8 = 15 × 8 = 120. Hence, 15 times 8 is 120. b) First, we will write 15 times 7 minus 5 mathematically.

Table of 15 up to 20.

15 × 11 = 165 15 × 16 = 240

15 × 14 = 210 15 × 19 = 285

15 × 15 = 225 15 × 20 = 300
