5x-2y=-6 3x-4y = -26​

Mathematics

snow_tiger [21]3 years ago

For this case we must solve the following system of equations:

5x-2y = -6\\3x-4y = -26

We multiply the first equation by -2:

-10x + 4y = 12

We add the new equation with the second one:

-10x + 3x + 4y-4y = 12-26

We have different signs subtracted and the sign of the major is placed:

-7x = -14\\x = \frac {-14} {- 7}\\x = 2

Now we find the value of the variable "y":

3x-4y = -26\\3 (2) -4y = -26\\6-4y = -26\\-4y = -26-6\\-4y = -32\\y = \frac {-32} {- 4}\\y = 8

Thus, the solution of the system is given by:

(x, y) :( 2,8)

Answer:

(x, y) :( 2,8)

which set of steps shows the solution to the equation 2y = −8? y = −8 − 2; y = 6 y = −8 ÷ (−2); y = 4 y = −8 ÷ 2; y = −4 y = −8
xz_007 [3.2K]

Answer:  The correct option is

(C) y = −8 ÷ 2; y = −4.

Step-by-step explanation:  We are given to select the correct steps that shows the solution to the following equation :

2y=-8~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

the solution to the equation ax=b,~~\textup{a,b are real numbers} is given by

ax=b\\\\\Rightarrow x=b\div a.

Therefore, the solution of equation (i) is as follows :

2y=-8\\\\\Rightarrow y=-8\div 2\\\\\Rightarrow y=\dfrac{-8}{2}\\\\\Rightarrow y=-4.

Thus, (C) is the correct option.

How many different digits are needed for the base 6 system?​
lorasvet [3.4K]

Answer:

0, 1, 2, 3, 4 and 5

Step-by-step explanation:

In a nutshell, base six  is a number system that employs the numbers 0 through 5 instead of 0 through 9 in each digit. As a result, a number that would be stated as 6 in base ten is written as 10. We count one, two, three, four, five, ten, eleven, twelve, thirteen, fourteen, fifteen, twenty, and so on.

The perimeter of a square is 4/5 what is its area
34kurt

Answer:

1/25

Step-by-step explanation:

square has 4 sides, if you add them all up you get 4/5.

1/5+1/5+1/5+1/5=4/5

so each side is 1/5

Area=length * width

A=1/5*1/5=1/25

If F(x) = log 5 2x, find F^-1(x). a. 5^y=2x b. 5^2y=x c. y = (5^x)/2
gregori [183]

Answer:

y = \frac{5^{x} }{2}

Step-by-step explanation:

y = log 5 2x

inverse ------> y=x

x = log 5 2y

5^{x} = 2y

y = \frac{5^{x} }{2}
