In order to find x-intercepts, you need to solve each binomial when it is equal to zero.

(x - 1)(x - 4)(x + 7)

x - 1 = 0
x = 1

x - 4 = 0
x = 4

x + 7 = 0
x = -7

Find the least common multiple of 8c4 and 6c2 .
Ksju [112]
The least common multiple is the smallest term that can be divided to both terms without any remainder. For the two terms 8c^4 and 6c^2, you can determine it into two part. First, you find the LCM for 8 and 6. You find the prime number that is common between the two. That would be 2. For the variables c^4 and c^2, the 'prime variable' is c. Therefore, the least common multiple for 8c^4 and 6c^2 is 2c.

A music website charges x dollars for individual songs and y dollars for entire albums. Person A pays $25.92 to download 6 indiv
Elena-2011 [213]
Let x equals to amount charged for downloading individual songs \Rightarrow y equals to amount charged for downloading an entire album.

Solve the system for y:
\left\{{{6x+2y = 25.92,}\atop{4x + 3y = 33.93;}}\right \left\{{{6x+2y = \frac{648}{25},}\atop{4x + 3y = \frac{3393}{100};}}\right
\\\left\{{{6x+2y-2y = \frac{648}{25}-2y,}\atop{4x + 3y = \frac{3393}{100};}}\right \left\{{{6x = \frac{648}{25}-2y,}\atop{4x + 3y = \frac{3393}{100};}}\right
\\\left\{{{x = \frac{-25y+324}{75},}\atop{4x + 3y = \frac{3393}{100};}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{4\frac{-25y+324}{75} + 3y = \frac{3393}{100};}}\right
\left\{{{x = \frac{-25y+324}{75},}\atop{\frac{4(-25y+324)}{75} * 300 + 3y * 300 = \frac{3393}{100} * 300;}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{16(-25y+324)+900y = 10179;}}\right
\\\left\{{{x = \frac{-25y+324}{75},}\atop{500y+5184 = 10179;}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{500y = 4995;}}\right
\\\left\{{{x = \frac{-25y+324}{75},}\atop{y = \frac{999}{100} = 9.99;}}\right

Solving the system for x is unoptional since we already have the answer we've been looking for. Your answer is 9.99\$.

What is the value of the following expression 7+18÷(6-3)
EleoNora [17]
First use PEMDAS

Parenthesis
Exponents
Multiplication
Division
Addition
Subtract

(6-3) That is 3, so now make your new equation which would be:
7+(18<span>÷3)
Then divide or use multiplication to find what multiply by 3 to get 18 which is 6x3 then get your new equation,
7+6 and your done! Just add and there you go ^_^</span>
