The inequality is TRUE because when you substitute 4 into each variable (p), you will have this:
3(4) > 5 + 4
12   >   9
12 is greater than 9, so the inequality is definitely true.

What is the sum of the arithmetic sequence 6, 14, 22 …, if there are 26 terms? 2,754 2,756 2,758 2,760 -

This is the concept of sequences and series;
The sum of arithmetic series is given by:
Sn=n/2(2a+(n-1)d)
n=number of terms
a=1st term
d=common difference
From our sequence;
a=6, d=8, n=26
hence;
Sn=26/2(2*6+(26-1)8)
Sn=13(12+25*8)
Sn=13(12+200)
Sn=13(212)
Sn=2,756
The answer is 2,756

Answer:

Option B - y=99.07\times 0.68^x

Step-by-step explanation:

Given : The data set of the equation.

To find : What is the exponential regression equation for the data set?

Solution :

Data table

x    y

1    56

3    44

3    41

5    11

4    22

8    3

11    2

Using regression calculator we get an exponential regression equation for the data set above is y=99.07\times 0.68^x

As exponential function is in the form y=ab^x

Where, a is the initial value, a=99.07

and b is the rate factor, b=0.68

Refer the attached figure for the regression calculations.

Therefore, Option B is correct.

1. Simplify the expression. Show your work .and steps 22 + (3^2 – 4^2)

PEMDAS...parentheses, then exponents, then multiplication/division, finally addition/subtraction...

22+(3^2-4^2)  inside the parentheses are exponents, so they are calculated first.

22+(9-16)  now you complete the operations inside the parentheses

22+(-7)  finally you do your addition/subtraction

Center ( 9,-8 ), passes through ( 19,22 )

Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so given
center at (9,-8)

(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²

input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r

well, the equation is
(x-9)²+(y+8)²=1000

The diameter of a bicycle tire is 22 inches. About how many revolutions does the wheel make during a ride a ride of 600 feet? Use 3.14 for pi. Explain your answer

So the tire has a diameter of 22 inches, now the radius of that will he half the diameter, or 11inches

so, the circumference of it will be \bf C=2\pi r\implies 2\cdot 11\pi \implies 22\pi

how many revolutions.. on 600 feet,   well, how many inches in 600 feet?

1ft is 12inches, so 600 * 12 is 7200 inches

now, one revolution is just a go-around the circle or 2π, a full circle
we know the circumference covered in a full circle with radius of 11, or diameter of 22, in a go-around is 22π

how many 22π are there in 7200 inches? well   \bf \cfrac{7200}{22\pi }   that many

QUESTION POSTED AT 16/10/2019 - 07:10 PM

Henrique began to solve a system of linear equations using the linear combination method. His work is shown below: 3(4x – 7y = 28) → 12x – 21y = 84 –2(6x – 5y = 31) → –12x + 10y = –62 12x – 21y = 84 + –12x + 10y = –62 –11y = 22 y = –2 Complete the steps used to solve a system of linear equations by substituting the value of y into one of the original equations to find the value of x. What is the solution to the system?

Answer:

Henrique began to solve a system of linear equations using the linear combination method:

Given the System of equation :

4x-7y=28                    ....[1]

6x-5y=31                    ....[2]

Multiply equation [1] by 3 to both sides we have;

3(4x-7y)=3(28)

12x-21y = 84                  ....[3]

Multiply equation [2] by -2 to both sides we have;

-2(6x-5y)=-2(31)

-12x+10y = -62              ....[4]

Add equation [3] and [4] to eliminate x and solve for y:

-11y =22

Divide both sides by -11 we have;

y = -2

Substituting the  value of y into equation [1] to solve for x.

4x-7(-2)=28

4x+14=28

Subtract 14 from both sides we have;

4x=14

Divide both sides by 4 we have;

x = 3.5

Therefore, the solution to the system is, (3.5, -2)
