Find the solution to the system of equations. write in ordered pairs.
5x-4y=-10
3x+2y=16

(2,5)

Step-by-step explanation:

5×-4y=10

+2 (3×+2y=16)

11×+0y=22

11×=22

×=2

5×-4y=-10

5(2)-4y=-10

10-4y=-10

-4y=-20

y=5

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
