Write 9x-3y=-69 x − 3 y = − 6 in slope-intercept form. Make sure you show all steps and inverse operations.Write 9x-3y=-69 x − 3

Goryan [66]

Answer:

y = 3x + 23 and

$y = \frac{1}{3}x + 2$

Step-by-step explanation:

The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.

Now, 9x - 3y = - 69

⇒ 3x - y = - 23 {Dividing both sides by 3}

⇒ 3x + 23 = y

⇒ y = 3x + 23 {Interchanging the sides} (Answer)

The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.

Now, x - 3y = - 6

⇒ x + 6 = 3y

⇒ 3y = x + 6 {Interchanging the sides}

⇒ $y = \frac{1}{3}(x + 6)$ {Dividing both sides by 3}

⇒ $y = \frac{1}{3}x + 2$ (Answer)

1) Refer back to Lesson 2, Part A. Assume that the average shoulder width of the people in the line was 1.325 feet. How long wou

igor_vitrenko [27]

Answer:

13,250,000 feet or 13.25 million feet

Step-by-step explanation:

Each person in the line has a shoulder width of 1.325 feet.

For each person, there is a width of 1.325 ft. There are 10 million people.

Since:

10 million = 10,000,000

The total length must be:

$1.325 * 10,000,000$

$1.325 * 10,000,000 = 13,250,000$

Answer: 13,250,000 feet or 13.25 million feet

Roughly estimate the volume of a tennis ball in cubic cm by using 6 cm for diameter and 3 for pi. round the answer to the neares

galben [10]

The volume of ball is 113.04 cubic centimeter

Solution:

Given that we have to find the volume of tennis ball

Since the ball is of sphere shape, we can use the sphere formula

The volume of sphere is given by formula:

$V = \frac{4}{3} \times \pi \times r^3$

Where, "V" is the volume and "r" is the radius

Given that,

Diameter = 6 cm

Therefore,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{6}{2}=3$

Substituting in formula, we get

$V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04$

Thus volume of ball is 113.04 cubic centimeter
