Pleasee help me with my Math is important and I need help

19. Y = 3x - 2

20. Y = -x - 6

21. Y = -2x + 2

22. Y = -5x + 14

23. Y = 6x - 3

24. Y = 3x + 23

25. Y = 1/2x + 5

26. Y = 1/3x + 2

27. Y = x + 1

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=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:
