Answer:
a = 7 and c = 12
Step-by-step explanation:
Set up 2 equations and use substitution:
4a + 2c = 52
12a + 4c = 132
In the first equation, c = 26 - 2a
We can plug that into the second equation to solve for a.
12a + 4(26 - 2a) = 132
a = 7
Plug a back in to either original equation to solve for c:
4(7) + 2c = 52
c = 12

Answer:
Step-by-step explanation:
Simplify, remember, an exponent raised to the power of another exponent is equal to the product of the two exponents,
Now bring the term in the denominator (number under the fraction bar) to the numerator (number over the fraction bar). This can be done by multiplying the exponent of the denominator by (-1).
Simplify,
Remember, multiplying two numbers of the same base is the same as adding their exponents, apply this property here,
Dividing two numbers of the same base is the same as subtraction their exponents,
Thus, the following statement can be made,
Step-by-step explanation:
(1\2)^4 x 1\16 x 1\8 x 1\4 [1/2^4=16]
1/16 x 1/512
=>1/2048
To find the domain and range is very simple. The domain will always be the input values or x values. For example ( 3,0) the domain is 3 being the x value. The range is the output value or y value and in the example (3,0) the range is 0. Hope this helps :)
