7x+2y=24, -8x-2y=-30

Mathematics
1 answer:
oksano4ka [1.4K]3 years ago
3 0

Answer:

x= 6, y = -9

Step-by-step explanation:

7x+2y=24,

-8x-2y=-30

Add the two equations together to eliminate y

7x+2y=24

-8x-2y=-30

----------------------

-x +0y = -6

Divide each side by -1

x = 6

Now solve for y

7x+2y = 24

7*6 +2y = 24

42 +2y = 24

Subtract 42 from each side

42-42 +2y = 24-42

2y =-18

Divide each side by 2

2y/2 = -18/2

y = -9

A cylinder has a height of 12 inches and a radius of 1.5 inches. What is its voulme? Round your answer to the nearest tenth. Use
Lerok [7]

Answer:

It's volume is of 84.78 cubic inches.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder with radius r and height h is given by:

V = \pi r^2h

A cylinder has a height of 12 inches and a radius of 1.5 inches.

This means that h = 12, r = 1.5

What is its volume?

V = \pi r^2h = 3.14(1.5)^2(12) = 84.78

It's volume is of 84.78 cubic inches.

How can you rewrite the expression (8-5i)^2 in the form a+bi?
otez555 [7]
(a-b)^2 = a^2-2ab+b^2

(8-5i)^2 = 8^2-2(8)(5i)+(5i)^2

= 64-80i+25i^2

i^2=-1

So

= 64-80i+25(-1)

=64-25-80i

= <em><u>39 - 80i</u></em>

which is your answer :)
