5x-2y=-6 3x-4y = -26​

Mathematics

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)

Convert 18 centimeters per second to meters per hour.<br> hint: 1 m = 100 cm
denis-greek [22]

Answer:

The answer to your question is 648 m/h

Step-by-step explanation:

           

                  \frac{18 cm}{s} \frac{1 m}{100 cm} \frac{3600 s}{1 h}

                  \frac{(18)(1)(3600)}{(1)(100)(1)}

                  \frac{64800}{100}

                          = 648 m/h

Determine the x- and y-intercepts of the graph of y=−1/3x+3 .
Alinara [238K]

Answer:

x intercept

y = 0 \\ 0 =  \frac{1}{3} x + 3 \\  \frac{1}{3} x =  - 3 \\ x =  - 9

y intercept

x = 0 \\ y =  \frac{1}{3}  \times 0 + 3 \\ y = 3
