What is the solution to the linear equation? 4b + 6 = 2 – b + 4

Answers

Answer 1
Answer:

Answer:  The required solution is b = 0.

Step-by-step explanation:  We are given to solve the following linear equation :

4b+6=2-b+4~~~~~~~~~~~~~~~~~~~~~~~~(i)

We need to find the value of the unknown variable 'b' in the give equation.

From equation (i), we have

4b+6=2-b+4\n\n\Rightarrow 4b+6=6-b\n\n\Rightarrow 4b+b=6-6\n\n\Rightarrow 5b=0\n\n\Rightarrow b=(0)/(5)\n\n\Rightarrow b=0.

Thus, the required solution is b = 0.
Answer 2
Answer: b = 0

To solve make b the subject so:
4b + 6 = 2 - b + 4
5b + 6 = 6
5b = 0
5 = 0/5
= 0

The period of the secant function is 2π, the correct option is C.

What is the Period of a Function?

The period of a function is the value at which the function repeats itself.

The secant function is

f(x) = sec x

The period of the secant function can be determined from its graph.

A graph of y = sec x is plotted and the period is determined.

The period of the secant function is 2π, the correct option is C.

Jane has a checkbook balance of $68.00. She then writes two checks, one for $5.00 and one for $62.50. She also deposits $75.00. She then uses her calculator to determine her new balance. Which of the following is the correct series of keys she should press? A.ON/C 6 8 + 7 5 = 5 = 6 2 . 5 0B. 6 8 + 75 – 5 – 6 2 . 5 0C. ON/C 6 8– 5 – 6 2 . 5 0 + 7 5 =D. 6 8 + 75 – 6 2 5 0 – 5 =

Answers

C because you want to do the steps in order. She started out with $68 then you subtract $5 and & 62.50 Then you add the deposit of $75.00
C because 5 and 62.50 is what she took at of her account. But she put in $75 somyou add that

If you pay $8.50 per square yard of carpeting, what is your total cost for 27.5 square yards?a. $233.75
b. $223.75
c. $228.75
d. $232.75

Answers

Answer:

a.$233.75

Step-by-step explanation:

We are given that

Cost of 1 square yard of carpeting =$8.50

We have to find the total cost for 27.5 square yards.

Using unitary method

Cost of 27.5 square yards of carpeting =27.5* 8.50

After multiplying , we get

The cost for 27.5 square yards of carpeting =$233.75

Hence, the cost for 27.5 square yards of carpeting=$233.75

Answer:a.$233.75
the answer is A because if you pay $8.50 per square yard it means multiply. Per is the key word and then you just multiply $8.50 and 27.5 to get A

Step-by-step explanation:

These are all examples of p-series:

∑(1 / nᵖ), where p>0.

If p > 1, the series converges.  If 0 < p ≤ 1, the series diverges.

First option:

∑(1/n⁵)

Here, p = 5.  Since 5 > 1, the series converges.

Second option:

∑((√n+3)/n³)

∑((√n)/n³) + ∑(3/n³)

∑(1/n^2.5) + 3 ∑(1/n³)

In the first sum, p = 2.5.  In the second sum, p = 3.  Both are greater than 1, so the series converges.

Third option:

∑((n−4)/(n⁴√n))

∑(1/(n³√n)) − ∑(4/(n⁴√n))

∑(1/n^3.5) − 4 ∑(1/n^4.5)

In the first sum, p = 3.5.  In the second sum, p = 4.5.  Both are greater than 1, so the series converges.

Fourth option:

∑(1/∛n)

∑(1/n^⅓)

Here, p = ⅓.  This is less than 1, so the series diverges.

Note: if a series is converging, then the limit is 0.

However, if the limit of a series is 0, it does not necessarily mean that series is converging.

Here, the limit of all 4 options is 0.  However, the fourth option is a diverging series.
