You can rewrite the decimal as a fraction  and compare the two fractions.  The fractions need to have a common denominator.

You can change the fraction to a decimal and compare.  take the numerator and divide it by the denominator.  


Unless I recognize the decimal as a fraction right away, I find it much easier to write the fraction as a decimal and compare

Expand and simplify 2(a + 3) + 3(2a - 1)
Svetlanka [38]
2(a+3) + 3(2a-1)
First, let's use the distributive property to expand 2(a+3):
2(a+3) = 2*a + 2*3 = 2a + 6
Let's use the distributive property now to expand 3(2a-1):
3(2a - 1) = 3*2a - 3*1 = 6a - 3

So 2(a+3) + 3(2a-1) = 2a + 6 + 6a - 3
Now you calculate variables between each others, and numbers between each others:
2a + 6 + 6a - 3 = 2a + 6a + 6 - 3 = 8a + 3

So the simplified form of 2(a+3) + 3(2a-1) is 8a + 3.

Hope this Helps! :)

Can you draw different functions that have the same x-intercepts and the same domain and range?
iogann1982 [59]
I'm pretty sure the answer is no.  A function looks like this: f(x) = mx + c.  Let's add another function, f(y) = ny + d.  If the x-intercept is the same, we can subtract c and d from their respective equations. f(x) = mx, f(y) = ny. If the domains are the same, then x and y can have the same value, so we divide it out. f(x) = m, f(y) = n.  Finally, if the ranges are the same, the value of f(x) = f(y).  So by the substitution property, m=n.  Since all the variables equal each other, both functions are equal to f(x) = mx+c!  Therefore, they can only be the same function.

What is the factored form of x^3-1
polet [3.4K]

Answer:

the factors of x^3-1 are x^3 -1 = (x-1) (x^2 +x+1)\\

Step-by-step explanation:

We need to find factors of x^3 -1

x^3-1 \\(x)^3 -(1)^3\\We \,\, know\,\, a^3 -b^3 = (a-b) (a^2 +ab + y^2) \\So, \,\, using\,\, the \,\, formula\,\,\\Here\,\, a= x \,\,and\,\, b= 1\\(x)^3 -(1)^3 = (x-1) (x^2 +x+1)\\

So, the factors of x^3-1 are x^3 -1 = (x-1) (x^2 +x+1)\\

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15%
Katena32 [7]

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)
