Answer:
20xy + 5x -4y
Step-by-step explanation:
I hope this helps you
54 is 75% of x.
75% of x:

75% of x is (3/4)x and 75% of x is 54. Set (3/4)x equal to 54:

54 is 75% of
72.
An even function is symmetric with respect to the y-axis. One way to identify an even function is to check the exponents of its terms, all of which must be even. For constants, we assume the exponent is zero (still considered an even number for this purpose). The first function will have an odd exponent because the expansion has a 2x term. The second function has 8x, which is also an odd exponent of 1. The third function has an odd exponent in x.
The fourth function is just a constant (with exponent 0), so it is an even function.
It would actually be no solutions, since an equation can't have more than one equal sign xD
It’s (-2 , -2)
It has to be that answer
