Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.

Answers

Answer:

y = 3/5x - 17/5

Step-by-step explanation:

slope formula: (y₂ - y₁) / (x₂ - x₁)

First, plug in these values of the two given points.

(-4 - (-1)) / (-1 - 4)

Simplify within the parentheses.

(-4 + 1) / (-1 - 4)

(-3) / (-5)

3/5

This is your slope. Plug this into a standard slope-intercept equation: y = mx + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = 3/5(-1) + b

Multiply.

-4 = -3/5 + b

Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.

-20/5 = -3/5 + b

-20/5 + 3/5 = b

-17/5 = b

Now, plug this into your standard equation.

y = 3/5x - 17/5

Check this equation by plugging in the other point you did not use (4, -1)

-1 = 3/5(4) - 17/5

-1 = 12/5 - 17/5

-1 = -5/5

-1 = -1

Your answer is correct!

Kwame fills a bird feeder with seeds. As
birds visit the feeder, the height of the
seeds changes from 13.6 cm to 11.1 cm
over a period of 6 1/4 hours. What is the
average change in the height of the seeds
each hour?

Answers

Answer:

Step-by-step explanation:

Givens

Time = 6.25 hours

distance = 13.6 cm - 11.1 cm = 2.5 cm

Formula

rate = distance / time

Solution

rate = 2.5 / 6.25

rate = 0.4 cm/hour

If angle 1 = 55°, what is angle 5?
A. 55°
B. 40°
C. 35°
D. 25°

thanks ;)

Answers

It’s C because 90-55

It’s C i believe
Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY

Answers

Answer:

x=2

Step-by-step explanation:

Simplify both sides of the equation.

2x−1−(−x + 3)=6−2x

(Distribute the Negative Sign)

2x−1 + −1(−x + 3)=6−2x

2x + −1 + −1(−x) + (−1)(3)=6−2x

2x + −1 + x + −3=6−2x

2x + −1 + x + −3=6 + −2x

(Combine Like Terms)

(2x + x) + (−1 + −3)=−2x+6

3x + −4=−2x + 6

3x−4=−2x + 6

Add 2x to both sides.

3x−4 + 2x=−2x + 6 + 2x

5x−4=6

Add 4 to both sides.

5x−4 + 4=6 + 4

5x=10

Divide both sides by 5.

5x/5=10/5

In order to get to work, Lindsay takes access roads that require a toll for drivers to use. She pays $4 each day to use the access roads. She also pays $5 each day to park her car at the company lot.

Answers

The ordered pair that represents how much she spends on a 5-day week is (20,25)

The rates are given as:

[tex]Access\ Roads = \$4[/tex]

[tex]Parking\ Lot= \$5[/tex]

From the question, x represents the access to roads, and y represents the number of days she parked her car.

So, her daily expense is:

[tex]Daily = Access\ Roads \times x + Parking\ Lot \times y[/tex]

This gives

[tex]Daily = 4\times x + 5\times y[/tex]

[tex]Daily = 4x + 5y[/tex]

For a 5-day work week, her daily expense is:

[tex]Daily = 4 \times 5 + 5 \times 5[/tex]

[tex]Daily = 20 + 25[/tex]

Express as ordered pair

[tex]Daily = (20 , 25)[/tex]

Hence, the ordered pair that represents how much she spends is (20,25)
