Step-by-step explanation:
Using the rules of radicals/ exponents
×
=
⇔
Simplifying each term
7 = 7
x
= x × ×
= x × 3 ×
= 3 ×
= 3
Subtracting the 2 simplified like terms, that is
7 - 3
= 4 ← return to radical form
= 4
Since the divisor is 2 digits, start by looking at the first 2 digits of the dividend. Those are 44, so you're dividing 44 by 15 at the first step. The quotient digit is the largest integer that gives a value less than or equal to the dividend (44) when multiplied by the divisor (15). For the first step, that digit is 2.
To find the new divisor, subtract the product of the divisor and the quotient digit (2·15=30) and bring down the next digit of the original dividend. Now, you have a dividend of 147 and a divisor of 15. Repeat the process as above.
The decimal point location in the answer can be found a number of ways. The simpliest is to put it above the decimal point in the dividend. (When the divisor is not an integer, multiply or divide both divisor and dividend by the same power of 10 until it is.)
Answer:
Yes; domain: all real numbers; range: y 0
Step-by-step explanation:
1. Use the vertical line test to see if it is a function.
2. Figure out what the lowest and highest point x can be. In this case x can be any number
3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y 0
*Note: Domain are the x values & Range are the y values
