The points ( − 1. 6 , 2. 6 ) and ( 3. 4 , 9. 1 ) are on the graph of a . . . The points (−1 6,2 6) and (3 4,9 1) are on the graph of a linear relationship between two variables, x and y What is the constant rate of change of y with respect to x? Write a formula that expresses y in terms of x What is the value of y when x=113?
Find g(x), where g(x) is the translation 5 units up of f(x)=x. g(x) = f(x) + 5 One of the easiest ways to check this is using a linear equation Let's use f(x)=x+5 Here, the y-intercept is at 5 or (0,5) If you plug in that equation into f(x) in the equivalence g(x)=f(x), then you get g(x) = f(x) + 5 g(x) = (x+5) + 5 Notice that you can get rid of the parentheses right away and simplify g(x) = x + 5
Compute the frequency (in MHz) of an EM wave with a wavelength . . . - Wyzant velocity = frequency x wavelength Therefore frequency = velocity wavelength Remember that for an EM wave, velocity is always the speed of light This means that frequency = c wavelength Remember the units for c and wavelength must match appropriately
Combustion Analysis: Empirical and Molecular Formulas A 7 333 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 18 96 grams of CO 2 and 3 882 grams of H 2 O are produced In a separate experiment, the molar mass is found to be 136 2 g mol Determine the empirical formula and the molecular formula of the organic compound
Solve using distance, time, and rate using a system of linear . . . - Wyzant So, 660 is his rate in still air minus the effect of the Jetstream; that is, y - x = 660 When he is flying with the Jetstream, the Jetstream increases his rate in still air (y) by x units When he flies with the Jetstream, his rate is (5600 miles) (5 hrs) or 1120 mph So, y + x = 1120 So, we have two equations: y - x = 660 y + x = 1120
How do i balance this equation? C8H18 +O2 - gt; CO2 + H2O There are a total of 25 O's on the right So you'd need 12 1 2 O 2 's to balance that You can't have halves of anything, so you'll have to multiply everything by 2 to get rid of the fraction:
