Answer:

h = 59 hours

Step-by-step explanation:

Total earnings = fixed charge + variable charge

Fixed charge = $65

Variable charge = $15h

Where, h = number of hours

Total earnings = $950

Total earnings = fixed charge + variable charge

950 = 65 + 15h

Subtract 65 from both sides

950 - 65 = 65 + 15h - 65

885 = 15h

Divide both sides by 15

h = 885 / 15

= 59

h = 59 hours

Answer:

973,764

Step-by-step explanation:

Answer: you have: C(X)=3x+2.00

x=number of minutes

Pay attention to the y=mx+b form where m=slope-->>

3x is the slope...

so it's 3(times the number of minutes) <<---or (x)

This means that the slope is 3, or the fancy way of saying it-->>"rate of change."

Answer:

$5

Step-by-step explanation:

Let

x = initial fee

y = fees depending on the amount of data he use

After using 3 GB of data , he owes $30.

After using 5 GB of data , he owes $40.

The equations are

x + 3y = 30 (1)

x + 5y = 40 (2)

Subtract (1) from (2) to eliminate x

5y - 3y = 40 - 30

2y = 10

Divide both sides by 2

y = 10/2

y = $5

Substitute y = 5 into (1)

x + 3y = 30

x + 3(5) = 30

x + 15 = 30

x = 30 - 15

x = $15

Cost per GB of data = $5

Answer:

y=3x+5

Step-by-step explanation:

For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel,  both slopes are equivalent.

First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:

y-(2)=3(x+1)

y-2=3x+3

y=3x+5

Check:

(2)=3(-1)+5

2=-3+5

2=2

Answer:

y=x+4

Step-by-step explanation:

y=mx+b

Answer:

40 degrees

Step-by-step explanation:

There are parallel lines and a transversal. That means that angle a and b are congruent due to corresponding angles theorem.

5x-5=3x+13

Move the variables on one side and numbers on the other. 2x=18

Finally, x=9 And then after you plug it in, your final answer for angle b is 40 degrees.

Answer:

Step-by-step explanation:

Well both angles are the same because the lines are parallel and then there is a line going through them so <A = <B   meaning

5x-5=3x+13 and then you solve

5x - 3x = 13 + 5

2x = 18

x = 9

Algebraic notation is a method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard.

The measure of angles  ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

We have been given that m angle ∠1 = 79°,

To determine the measure of each numbered angle.

As per the property supplementary angles,

m∠1  + m ∠2 = 180°
79° +  m ∠2 = 180°

m ∠2 = 180° - 79°

m ∠2 = 101°

If a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

∠1 = ∠4 = 79°

∠2 = ∠3 = 101°

∠2 =  ∠6 = 101°

∠4 = ∠5 = 79°

∠5 = ∠8 = 79°

∠6 =  ∠7 = 101°

Thus, the measure of angles  ∠1, ∠4, ∠5, ∠and 8 will be 79°. The measure of angles ∠2, ∠3, ∠6, and ∠7 will be 101°.

Answer:

4

Step-by-step explanation:

f(x) = 12 and f(x) = 3x

12/3 = 4 and the function for f(x) is 3(4)

The derivative of the function f(x) = 3x - 12 is 3.

Derivative of a function measures the rate of change of a function it can also be defined as the slope of the function.If given dy/dx it states the rate of change of y with respect to x.

According to the given question we have find the first derivative of the function f(x) = 3x - 12.

Given f(x) = 3x - 12

f'(x) = 1(3)x¹⁻¹ + 0                             ( derivative of any constant is 0 )

f'(x) = 3x⁰.

f'(x) = 3.

Answer:

1.) x+2

2.) x+4

Step-by-step explanation:

I got it right on Edge, hope this helps

The expression represents the second consecutive odd integer is X + 2

and for the third consecutive odd integer is X + 4.

All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a set of integers is formed.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.

Given One example of consecutive odd integers would be 3, 5, 7, 9, ...

the difference between 2 consecutive numbers is

5 - 3 = 2

when X is the first odd integer,

the second consecutive odd integer is X + 2

difference between 3rd and first digit is

7 - 3 = 4

the third consecutive odd integer is X + 4

Hence adding the consecutive even numbers to the first digit of odd numbers gives the consecutive odd numbers.

Answer:

19 kilometers

Step-by-step explanation:

2.5 kilometers  +  7kilometers

=  9.5 kilometers

+ the additional 9.5 for the trip down

=19 kilometers in total

Stacey total distance for climbing was 16.5 km

Stacey started 2.5 km up the cliff so this 2.5km is not counted as she started at that point.

She then climbed 7 km up the cliff.

After that she climbs back down to the bottom of the cliff. This time she climbs both the 7km she climbed previously, and the 2.5km she hadn't climbed before.

Tracy total climbing distance is:

= Distance climbed up + Distance climbed down

= 7 + ( 7 + 2.5)

= 7 + 9.5

= 16.5 km

In conclusion, Stacey climbed 16.5 km in total.
