Melvin analyzed prices of laptop computers based on the speed of the processor. He calculated the trend line to be y = 103x + 205 where x is the speed of the processor in gigahertz and y is the price. Which amount below is closest to the price of a laptop with a processor speed of 2.0 gigahertz?

x = 12

y = 15

step-by-step explanation:

sup

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
