Step-by-step explanation:

If m∠10 = 70, then find the m∠14 and state the angle relationship.

Answers

The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles

Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.

Since the angles are supplementary, hence the required expression will be:

m∠10 + m∠14 = 180

Given that m∠10 = 70 degrees

70 + m∠14 = 180

m∠14 = 180 - 70

m∠14 = 110 degrees

Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

Answer:

y = -3/4(x -2)

Step-by-step explanation:

You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...

m = rise/run = -3/4

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m = -3/4 and (h, k) = (2, 0), the equation is ...

y = -3/4(x -2)

_____

Additional comments

If you use the distributive property to eliminate parentheses, the equation becomes ...

y = -3/4x +3/2

The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...

m = rise/run = 4/3

The slope of the perpendicular (red) line is the opposite reciprocal of this:

-1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph

han the retail price. How much did the bicyclist spend on her racing bike?

Answers

Answer:

$1,260

Step-by-step explanation:

You first need to find 30% of 1,800, which is 540. And then, because it's 30$ less than retail price, you would need to subtract that from the initial price:

1,800-540 = 1,260

This means that at x = 1, y = 15, which is where we get "+ 15"

1. Beth works at the mall for $12.75 per
hour. She works for 41 hours per day on
2 days each week. How much does she
make in 2 weeks? (before taxes)?

Answers

Answer:

$2091

Step-by-step explanation:

We know:

12.75 per hour (h)

41 hours each day twice a week: each week (41 x 2) = 82

Since it is asking for two weeks: 82 x 2 = 164 hours

164 x 12.75 = $2091

PLEASE HELP WITH PART B!!

can you also explain y and x, I dont understand part B >

Answers

A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.

average rate of change:

($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year

initial value:

$350

B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.

If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is

(450 - 350) / (1 - 0) = 100/1 = 100

which is the same as the average rate of change.

Using the point-slope formula for a line, the equation you want is then

y - 350 = 100 (x - 0)

y - 350 = 100x

y = 100x + 350

11. Liza earned some money delivering newspaper .She bought a

for $7.20, and then spent half of the remaining money on a radio.
If Liza has $38.50 left, how much money did she earn delivering
newspapers?
anonh the solution set.

Answers

Answer: $116.15

Step-by-step explanation:

We first would start with the last thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.

All of these are subtractions from the initial amount:

x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50

x - 77.65 = 38.50

x = $116.15

f(x) = 5x + 25 - 1
8(x) - - 2x-3

Answers

Answer:

f(x)=5x+25-1

8(x)- -2x-3

=30-1

=8x+6x

The point of intersection of the two functions is (3, 27).

The system of equations is:

f(x) = 5x + 25 - 1 = 5x + 24

g(x) = 2x - 3

To solve this system, we can use the elimination method. We can eliminate the x-term by adding the two equations together.

f(x) + g(x) = 5x + 24 + 2x - 3 = 7x + 21

Solving for x, we get:

x = 21/7 = 3

Now that we know the value of x, we can plug it back into either equation to find the value of y. Let's use the equation for f(x).

f(x) = 5x + 24

f(3) = 5(3) + 24 = 27

Therefore, the point of intersection of the two functions is (3, 27).

To the nearest tenth, the point of intersection is (3.0, 27.0).
