Solve the system by substitution 3x+y=-16 and y=-x-4

Mathematics

kap26 [50]3 years ago
7 0

Solution,

y = -x-4......(i)

3x + y =- 16.......(ii)

Now,

Substituting the value of y in equation (ii)

or, 3x + (-x-4)= -16

or,3x - x - 4 = -16

or, 2x= -16 +4

or, x = -12/2

: x = -6

Then,

Substituting the value of x in (i) equation;

or,y= -(-6) - 4

or,y= 6 - 4

: y =2

Can anyone give me some insight on this?
NISA [10]

Disagree, because a polygon has to have sides to be a polygon. A circle has no defined sides to categorise it as such. A circle is a closed system, but can be seen as a cycle that lasts until the world ends. Like infinity, a circle is infinite by definition because it goes on forever. Like the polygon comparison, a circle is technically in a different category. Infinity is typically described as a time full of endless possibilities while a circle is just that, a cycle that will repeat itself over the course of forever.

So still disagree on that argument. Please tell me this is for a Philosophy class or something, because having this as a math problem is horrible.

How can you move just one number to a different
alexandr1967 [171]

Answer:

Remove 9 from triangle B to A

Step-by-step explanation:

Given

Three Triangles

A: 1,2,3

B: 7,8,9

C: 4,5,6

Required

Make their sum equal

First, we need to calculate the sum in each triangles;

A = 1 + 2 + 3

A = 6

B = 7 + 8 + 9

B = 24

C = 4 + 5 + 6

C = 15

Remove 9 from triangle B to A

A = 6 + 9

A = 15

B = 24 - 9

B = 15

At this point, we have:

A = 15     B = 15     C = 15

<em>Hence, the solution is to remove 9 from B to A</em>

PLS HELP <br>find the unknown side of the triangle below (round to the nearest tenth) <br>​
Nonamiya [84]
22.9 is the closest but not exact. It was probably rounded off.

I used the formula: leg^2+leg^2=hypotenuse^2

(You can use that formula for any right triangle.)
