im learnin about y=mx+b 1.describe the line you think each equation represent Y=x, y=5, x=-3 2. The equation of a line is y=mx+2. determione the value of m when the line passes through each point D(12.5) s(1.-3) e(-2.6) a(-5.1)

the serface of our earth is 20'c for every km, k below the surface the tempature increses by 10'c. let t represent the tempature in 'c 1a write an equation that represent the relationship between disatnce k and t tempature 1b. what is the slope and and y-intercept

At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of vi = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.00 s, the particle's velocity is v = (6.60 i + 4.00 j) m/s. Find the acceleration of the particle at any time t. (Use t, i, an...

Mr. S, a dealer of musical instruments, persuades me to buy an electronic organ, orally promissing that I can return the organ if I cannot learn how to play it. I signs a standard written form contract, which does not include this provision. I will not be able to testify as to...

I am sorry for my unclear explanation. Actually the monitor is powered by a 9V 100mA adaptor. I am not sure if the voltage drop across the speaker is AC or DC because the voltage keep changing from 0.9V to 1.5V on my voltmeter. Current is around 3.8mA. The microcontroller is p...

Hi everyone! I'm new in here. Recently I bought a movement monitor which detects micro movement. If the sensor does not detect a movement in 20 seconds, the build-in speaker will beep until the sensor detects a movement. I'm using it for my project and I have a questio...

math, basic
how do you write 5 and a half in a fraction not like this because i thought it was 5 1/2 but it was wrong. 5 1/2 is also 11/2, which is considered an improper fraction. I hope this is what you were asking.

math,help
I definately do not understand this problem. If y varies directly with x, and y = 600 when x = 1000, find the constant of variation K. If y is directonally (proportional) to x, then for every value of x there is a value for y multiplied by a constant value. So if was that we h...

What is the equation i have to use for the following question A roof rises 9.75 ft over a horizontal distance of 15.84ft. What is the slope of the roof to the nearest hundredth? Slope is given by slope=rise/run So what is the rise and what is the run?
