A single equation representing both lines x+y=0 and x+2y = 0 is ?​

Mathematics
1 answer:
kolbaska11 [484]3 years ago
4 0

Answer:

The single equation is y = 0

Step-by-step explanation:

We are given the following system of equations:

x + y = 0

x + 2y = 0

From the first equation:

x = -y

Replacing in the second equation:

-y + 2y = 0

y = 0

The single equation is y = 0

Tom started a savings account that earned $168 an interest in eight years with an annual rate of 7% simple interest what was the
Goryan [66]

Answer:

Step-by-step explanation:

I = PTR/100

Given from the question:

I = $168

R = 7%

T = 8

P = ?

Substituting into the formula , we have

168 = P X 8 X 7 / 100

168 X 100 = 56P

16800 = 56P

Therefore

P = 16800/5

P = 300

Therefore the original amount in the account is $ 300

How do you solve R= us for u
Pachacha [2.7K]
The answer is:  " u = R/s " .
________________________________________________
 
Given:  R = us ;  Solve for "u" ;

Divide each side of the equation by "s" to isolate "u" on one side of the equation; and to solve for "u" ;

R/s = [us] / s ;

R/s = u ;

↔    u = R/s .

Please help me out please
olganol [36]

if your teacher allows the pi symbol then your answer is 2513. if your teacher requires you to use 3.14 for pi then your answer is 2512. basically you use the Pythagorean theorem to find the height, and then plug the height (24) and the radius which is half the diameter (10) into the equation to find the volume of the cone. if you have any other questions about it please ask! hope this helps:)

100 pints help would be greatly appreciated
Veronika [31]

Answer:

  (4, -2)  (see attached)

Step-by-step explanation:

Vector addition on a graph is accomplished by placing the tail of one vector on the nose of the one it is being added to. The negative of a vector is in the direction opposite to the original.

__

<h3>vector components</h3>

The components of the vectors are ...

  u  = (1, -2)

  v = (-6, -6)

Then the components of the vector sum are ...

  2u -1/3v = 2(1, -2) -1/3(-6, -6) = (2 +6/3, -4 +6/3)

  2u -1/3v = (4, -2)

<h3>graphically</h3>

The sum is shown graphically in the attachment. Vector u is added to itself by putting a copy at the end of the original. Then the nose of the second vector is at 2u.

One-third of vector v is subtracted by adding a vector to 2u that is 1/3 the length of v, and in the opposite direction. The nose of this added vector is the resultant: 2u-1/3v.

The resultant is in red in the attachment.
