(x , 5/2)......so y = 5/2.....so do some subbing

y = x - 1/2
5/2 = x - 1/2....add 1/2 to both sides
5/2 + 1/2 = x
6/2 = x....reduce
3 = x

now check it...(3, 5/2)
y = x - 1/2
5/2 = 3 - 1/2
5/2 = 6/2 - 1/2
5/2 = 5/2 (correct)

so x = 3 <==

Find the least common multiple of 8x³y6z, 6x5z², and 10yzº.

kvv77 [185]

Answer:

The Least Common Multiple (LCM) of $8x^3y6z,6x5z^2, \text{ and } 10yz^0 \text{ is } 240 x^3yz^2$

Step-by-step explanation:

Definition of LCM

The LCM of a, b , c is the smallest multiplier that is divisible by a, b and c

Here the three terms are :

$8x^3y6z$

$6x5z^2$

$10yz^0=10y$ since $z^0 = 1$

Factoring using prime factorization we get $8x^3y6z = 2.2.2.x^3.y.2.3.z$ ³

= $2^4\cdot \:3\cdot \:x^3\cdot \:y\cdot \:z$ (1)

Factoring $6x5z^2$ we get

$2\cdot \:3\cdot \:5\cdot \:x\cdot \:z^2$ (2)

Factoring $10yz^0$ we get

$2 \;\cdot\; 5y$ ( $z^0 = 1)$ (3)

The LCM is the multiple of each of the highest power in each factor

$2^4\;.\;3\;.\;5\;.x^2\;.\;y\;.z^2 = 240 x^3yz^2$

Complete the equation of the line through (1,4) and (2,2) Use exact numbers. y=?

Aleks [24]

Step-by-step explanation:

slope = 2-4/2-1 = -2

y - 2 = -2(x - 2)

y-2 = -2x +4

y = -2x + 6
