The answer is A because if you factor out 3x^2y, you get 3x^2 - 2xy + y^2 and you cannot factor that out anymore
Answer: To clear an equation of decimals, multiply each term on both sides by the power of ten that will make all the decimals whole numbers. In our example above, if we multiply .25 by 100, we will get 25, a whole number. Since each decimal only goes to the hundredths place, 100 will work for all three terms.
So let's multiply each term by 100 to clear the decimals:
(100)0.25x + (100)0.35 = (100)(-0.29)
25x + 35 = -29
Now we can solve the equation as normal:
25x + 35 - 35 = -29 - 35
25x = -64
x = -2.56 Since the original was in decimal form, the answer should most likely also be in decimal form.
Let's look at one more:
1.75x + 4 = 6.2
We have to think a little more carefully about what multiple of ten to use here. 6.2 only needs to be multiplied by 10, but 1.25 needs 100, so we will multiply every term by 100. Don't forget to multiply the 4 by 100 as well.
(100)(1.75x) + (100)(4) = (100)(6.2)
175x + 400 = 620
We had to be extra careful as we multiplied by 100. Now we can solve the equation as normal:
175x + 400 - 400 = 620 - 400
175x = 220
x = 1.26
Step-by-step explanation:
The range of a function is all possible output, or y, values. The domain is all possible input, or x, values.
I case of y = x , domain and range are real number.
Answer:
a) 35
b) 22
Step-by-step explanation:
a) The amount of numbers to the right of the vertical line is the amount of people. Count them up and you get 35.
b) The amount of numbers that are greater than 14.0 is the answer. There are 22 of those numbers.
