Math
Yeah that's what I thought. But I wasn't sure which was greater, the larger exponent or the smaller one. It's kinda confusing when your dealing with decimals and negative exponents. But thankss :)

Math
Which expression represents the larger number? A. 40.1 x 10 to the -6 power B. 4.1 x 10 to the -7 power C. 0.411 x 10 to the -6 power D. 0.04001 x 10 to the -5 power I got A, but I'm not quite sure if it's the right answer :/

physics
a 650 newton crate rests on the floor. how much work is required to move it at a constant speed, 3 meters against a friction force of 150 Newtons

Solve the system using substitution. y = -2x + 5 3y = -x - 5 I already got the answer, just wanna make sure it's correct. Please show work as well.

Math
Solve each system x + 3y = 6 4x - 5y = 7 I need to know what x and y equal??

Math
Solve each system x + 3y = 6 4x - 5y = 7 I need to know what x and y equal??

Math
Oh alright I got it thank you :)

Math
What is 10x + 2y - 10 = 0 in slope intercept form ? and can you also explain how you got the answer cause I'm not really sure how to convert that into slope intercept (y = mx + b) m = slope and b = y intercept
