Answer:

x=2, y=1

Step-by-step explanation:

13x-12y=14

11x-4=18y or 11x-18y=4

13x-12y=14 /*3

11x-18y=4 /*(-2) then

39x - 36y=42 (1)

-22x+36y=-8 (2)

(1)+(2) 17x=34

-22x+36y=-8

x=34/17

-22x+36y=-8

x=2

-22*2+36y=-8

x=2

-44+36y=-8

x=2

36y=-8+44

x=2

36y=36

x=2

y=36/36

x=2

y=1

What is pi???????????????
Kipish [7]

Answer:

The ratio of a circle's circumference to its diameter

In other words: all the way around a circle divided by all the way across it.

The symbol is π (pi)

No matter how large or small the circle, its circumference is always π times its diameter.

π = 3.14159265358979323846... (the digits go on forever without repeating)

A rough approximation is 22/7 (=3.1428571...), but that is not accurate.

Suppose that the functions g and h are defined for all real numbers r as follows. gx) -4x +5 h (x) = 6x write the expressions fo
aleksandr82 [10.1K]

Answer: Our required values would be -10x+5, 2x+5 and -25.

Step-by-step explanation:

Since we have given that

g(x) = -4x+5

and

h(x) = 6x

We need to find  (g-h)(x) and (g+h)(x).

So, (g-h)(x) is given by

g(x)-h(x)\\\\=-4x+5-6x\\\\=-10x+5

and (g+h)(x) is given by

g(x)+h(x)\\\\=-4x+5+6x\\\\=2x+5

and (g-h)(3) is given by

-10(3)+5\\\\=-30+5\\\\=-25

Hence, our required values would be -10x+5, 2x+5 and -25.
