If x+y=6 and xy =2find x³+y³(please help me fast with explanation also please) T^T

Maurinko [17]

Answer: x³+y³=180

Step-by-step explain: let's remember the formula x³+y³=(x+y)(x²-xy+y²) and also x³+y³=(x+y)³-3xy(x+y) then $\displaystyle\boldsymbol{ x^3+y^3=\underbrace{(x+y)^3}_{6}-3\underbrace{xy}_{2}\underbrace{(x+y)}_6}=\\\\6^3-3\cdot 2\cdot 6=216-36=180$

How many solutions does 5(x - 3) + 6 = 5x - 10 have?<br><br>(Will mark brainlest)

FrozenT [24]

Answer:

None (x=∅)

Step-by-step explanation:

5(x - 3) + 6 = 5x - 10

5x-15+6 = 5x-10

-15+6+10=5x-5x

1 = 0

x = ∅

The graph of 4x+12y=8 and y=Mx+5 are perpendicular. What is the value of m

Komok [63]

Answer:

$m=3$

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

step 1

Find the slope of the given line

we have

$4x+12y=8$

isolate the variable y

$12y=8-4x$

$y=\frac{2}{3}-\frac{1}{3}x$

the slope of the given line is

$m=-\frac{1}{3}$

step 2

Find the slope $m_2$ of the perpendicular line to the given line

$m_1*m_2=-1$

$m_1=-\frac{1}{3}$ ---> slope of the given line

$(-\frac{1}{3})*m_2=-1$

$m_2=3$

therefore

The value of m is

$m=3$
