Answer:
The rational number equivalent to 3.24 repeating is 321/99
Step-by-step explanation:
To convert the decimal number to a rational number we can state this number and its multiples of 10, trying to find two number with identical decimal parts:
n=3.24242424...
10n=32.4242424....
100n=324.2424242...
Now, 100n and n have the same decimal part, then by subtracting these numbers we obtain:
100n-n=324.24242424...-3.24242424... = 321
99n = 321
n = 321/99
Answer:
sorry but the words are very blurry
Answer:
7
Step-by-step explanation:
f(x) means y, it is equal to the value of y, so f(x) = y
so, f(1) means to find the value of y when the value of x is 1, and that is 7, since 7 is the value of y indicated when the value of x is 1.
I hope this is helpful.

Answer:
Step-by-step explanation: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).
