The equation of the line that is parallel to the line y = 1/2x + 2 is: y = 1/2x + 5/2.

Recall that if two lines are parallel, they will have the same slope (m).

Slope of a line (m) = change in y / change in x.

The slope (m) of the equation, y = 1/2x + 2, that represents a line is 1/2.

This means that the line that is parallel to it will also have a slope (m) that is equal to 1/2.

Find the y-intercept by substituting m = 1/2 and (x, y) = (1, 3) into y = mx + b:

3 = 1/2(1) + b

3 = 1/2 + b

3 - 1/2 = b

5/2 = b

b = 5/2

To write the equation of the parallel line, substitute m = 1/2 and b = 5/2 into y = mx + b:

y = 1/2x + 5/2.

The Prime Factorization of 16807 are:7, 7, 7, 7, 7. This implies 7 raise to power 5.

The term "Prime Factorization" refers to determining which prime numbers multiply together to produce the original number.

The process of writing all numbers as a product of primes is known as prime factorization. As an example, suppose we have the number 20. We can divide this into two categories. "Well, that's 2 time 2 times 5," we can say. Also, 5 is a prime number.

In this case 16807 will be:

16807 ÷ 7 = 2401

2401 ÷ 7 = 343

343 ÷ 7 = 49

49 ÷ 7 = 7

7 ÷ 7 = 1

Again, all the prime numbers you used to divide above are the Prime Factors of 16807. Thus, the Prime Factors of 16807 are:7, 7, 7, 7, 7.

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

To find the y-intercept you need to put convert it into the equation:

y = mx + b where b = the y-intercept.

12x + 16y = 6. First rearrange the equation so y is on side of the equation.

16y = -12x + 6. Now divide by 16 so the equation has y as a stand alone value.

y = [tex]\frac{-3}{4}[/tex]x + [tex]\frac{3}{8}[/tex]

Therefore the y-intercept is [tex]\frac{3}{8}[/tex]

If ratio of a to b is constant, and a = 9 when b = 6 then value of b is 4/3 when a is 2.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

The ratio of a to b is constant,

a = 9 when b = 6.

We need to find value of b when a=2.

Let us consider the value be x.

Let us form an equation

9/6=2/x

Apply cross multiplication

9x=12

Divide both sides by 9

x=12/9=4/3

Hence, if ratio of a to b is constant, and a = 9 when b = 6 then value of b is 4/3 when a is 2.

The value of c is 0 guaranteed by the Mean Value Theorem for Integrals for the function 2x+1 on the interval [3,6].

Mean value theorem states, roughly, that for a given planar arc between two endpoints, there is at least one point at which the tangent to the arc is parallel to the secant through its endpoints.

Given.

Function is 2x+1 on the interval [3,6]

f(x)=2x+1

f(x) continuous on [3, 6] and differentiable on (3, 6) so the MVT applies here.

f(3)=7

f(6)=13

Average rate of change of f on [3,6]

= (13-7) / (6-3) = 6/3=2

To find the c-value guaranteed by the MVT, such that the instantaneous rate of change when x = c is 2, we differentiate, set f'(x) = 2, and solve:

f'(x) = 2 and x = 1.

c = 0 is the only c-value in the interval at which the instantaneous rate of change = the average rate of change.

The simple form of all the expressions are:

-3 + 4m + (-7) - 6m = -2m -10

6x + (-1) - 3x + 12 = 3x + 11

3xy +2z - 16 + 6xy = 9xy +2z - 16

-4x - 8 + 2x + (-3) - 5x = -7x - 11

Answer:

Interval for constant cost = [0, 10,000] same as 0 <= x <= 10,000

Interval for increasing cost = (10,000, ∞) same as 10,000 < x < ∞

Be careful! note the use of different types of parentheses for each answer part as explained below

Step-by-step explanation:

We are only being asked for the two intervals, not the function definition itself which would have made it a little bit more work. A function has inputs and outputs. Here the input is gallons of water and output is $ cost.

Normally when asked for intervals we use a variable. Let's call it x which represents the gallons of water used

Since there is a base rate of $11.70 whether or not any water is consumed as long as it is less than or equal to 10,000 gallons we can state that over the interval 0 to 10000 (inclusive), the cost is constant

We can represent this interval in two ways
0 ≤ x ≤ 10,000

Another way of representing this interval is what we call interval notation. In interval notation the same thing  can be expressed as:

[0, 10000]    

Here 0 is referred to as the lower limit or bound(minimum) and the 10,000 is referred to as the upper limit or upper bound

Note the use of square brackets. This means that both upper and lower limits are included in the function. Such an interval is also called a closed interval.

After 10,000 gallons, the cost keeps increasing. There is no upper limit on the usage of water. So the lower limit is 10,000  (but does not include that number) and upper limit is infinity

We represent this interval as
10000 < x < ∞

Note that both upper and lower limits are excluded since ∞ is not realistic.

In interval notation this is represented as
(10000, ∞)

Here we are using regular brackets(parentheses) because this interval does not include lower and upper limits

This kind of interval is known as an open interval

Looks like the purpose of this question is to make sure what you understand in terms of interval notation and possibly open and closed intervals. The only relevant number there is the 10,000 gallons which represents the upper bound on the first interval. All the other numbers can be junked

The values of the composite functions are

(r * q)(5) = 96

(q * r)(5) = 96

From the question, we have the following functions that can be used in our computation:

q(x) = x² + 7

r(x) = √(x + 4)

The composite functions are given as

(r * q)(5) and (q * r)(5)

The base functions of the above composite functions are

(r * q)(x) and (q * r)(x)

And they are calculated using

(r * q)(x) = r(x) * q(x)

(q * r)(x) = q(x) * r(x)

Substitute the known values in the above equations

So, we have the following equations

(r * q)(x) = (x² + 7) * (√(x + 4))

(q * r)(x) = (√(x + 4)) * (x² + 7)

Substitute 5 for x

(r * q)(5) = (5² + 7) * (√(5 + 4))

(q * r)(5) = (√(5 + 4)) * (5² + 7)

Evaluate the equations

(r * q)(5) = 96

(q * r)(5) = 96
