(algebra ii) extra the value of y for a given value of x, if y varies directly with x.
if y = -252 when x = 84, what is y when x = 74?
explain/show your work if you can
everything giving tia: )

  -222

Step-by-step explanation:

The new value of x is 74/84 of the old value, so the new value of y will also be 74/84 of the old value:

  (74/84)·(-252) = -222

If you like, you can solve for the constant of proportionality (k) in the equation ...

  y = kx

  -252 = k(84)

  -252/84 = k = -3

Then you can use this equation to find the new value of y.

  y = -3·74 = -222

__

As we have seen above, there is no need to discover the value of k if there is only one new x-value to be concerned with. If you have to find y for a number of new x-values, then it can be useful to know what k is.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
