What is the perpendicular line of 9x + 6y = -6

Mathematics
1 answer:
tangare [24]3 years ago
6 0

graphical form: 9*x +6*y=-6 simplifies to 9*x+6*y+6=0

text form: 9*x+6*y=-6 simplifies to 9*x+6*y+6=0

so 9*x+6*y=-6

9*x*y+6=0

simplify (9*x+6*y=-6)

I hope this helps you

Use the pythagorean theorem to find the distance between from A(5, -3) to B (6,0)
Orlov [11]

C. 3.16 is the right answer

Step-by-step explanation:

The distance formula used in coordinate geometry is derived from the Pythagorean theorem.

The distance formula is give by:

d=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}

Here (x1,y1) are the coordinates of first point and (y1,y2) are the coordinates of second point

Here,

(x1,y1) = (5,-3)

(x2,y2) = (6,0)

Putting the values in the formula

AB = \sqrt{(6-5)^2+(0-(-3))^2}\\=\sqrt{(1)^2+(0+3)^2}\\=\sqrt{(1)^2+(3)^2}\\=\sqrt{1+9}\\=\sqrt{10}\\=3.16\ units

The distance between two points is 3.16 units.

Hence,

C. 3.16 is the right answer

Emily is creating a rectangular garden in her backyard. The length of the garden is 12 feet. The perimeter of the garden must be
Westkost [7]

Answer:

The compound inequality:

30 ≤ 2L + 2w ≤ 64

w < 12

The range:

3 ≤ w < 12

Step-by-step explanation:

Let L be he length , w the width and p the perimeter

p=2L + 2w

30 ≤ p ≤ 64 ⇌ 30 ≤ 2L + 2w ≤ 64 ⇌ 30 ≤ 24 + 2w ≤ 64 ⇌ 6 ≤ 2w ≤ 40

⇌ 3 ≤ w ≤ 20

but ,since the width is less than the length then w < 12

then 3 ≤ w < 12

For a field trip, a highschool want to buy T-shirts and sweatshirts. The expression px + 29y repersents the cost of buying x T-s
marysya [2.9K]

Answer:

The value of p is $12.

Step-by-step explanation:

Given;

c = px + 29y ,,,,,,,,,,,,,,,,,,, (1)

Where;

c = cost of buying x T-shirts and y sweatshirts from the store

p = price of one or each T-shirt = ?

x = number of T-shirts bought

29 = price of one or each sweatshirt

y = number of sweatshirt bought

Based on the above breakdown, if each sweatshirt cost $17 more than a T-shirt, the value of p can be calculated as follows:

29 = p + 17

p = 29 - 17

p = 12

Therefore, the value of p is $12.

Additional note:

Note that this is not part of the question but it is just an example to make you understand the question better.

If we assume that 10 T-shirts and 10 sweatshirts are bought from the store, we can use equation (1) above to calculate the cost as follows:

Where;

c = cost of buying x T-shirts and y sweatshirts from the store = ?

p = price of one or each T-shirt = 12

x = number of T-shirts bought = 10

29 = price of one or each sweatshirt

y = number of sweatshirt bought = 10

Substituting the values into equation (1), we have:

c = (12 * 10) + (29 * 10)

c = 120 + 290

c = 410

Therefore, the cost of of buying 10 T-shirts and 10 sweatshirts from the store will be $410.
