$x^3+8y^6=x^3+2^3(y^2)^3=x^3+(2y^2)^3\\\\\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\x^3+(2y^2)^3=(x+2y^2)(x^2-(x)(2y^2)+(2y^2)^2)=(x+2y^2)(x^2-2xy^2+4y^4)$

$Answer:\ (x+2y^2)(x^2-2xy^2+4y^4)$

zubka84 [21]

Answer:

$35\ ways$

Step-by-step explanation:

we know that

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

$C(n,r)=\frac{n!}{r!(n-r)!}$

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

$n=7\\r=3$

substitute

$C(7,3)=\frac{7!}{3!(7-3)!}\\\\C(7,3)=\frac{7!}{3!(4)!}$

simplify

$C(7,3)=\frac{(7)(6)(5)4!}{3!(4)!}$

$C(7,3)=\frac{(7)(6)(5)}{3!}$

$C(7,3)=\frac{(7)(6)(5)}{(3)(2)(1)}$

$C(7,3)=35\ ways$

Write the equation of the line that passes through (3, 4) and (2, –1) in slope-intercept form.

matrenka [14]

1) slope is 6 and y-intercept is ( 0,5) y = mx + b, m = 6, b = 5 y = 6x + 5 2)line passes through the points ( 3,6) and ( 6,3 ) First find the slope: m = (3-6)/(6-3) = -3/3 = -1 y = -x + b Plug in one of the given points (x,y) and find b 6 = -3 + b 9 = b y = -x + 9 a horizontal line that passes through the point ( -1,7)Horizontal lines have a constant y-value and formaty = c where c is a constant number. y = 7 y=-3x+3x intercept: set y = 0 and solve for x0 = -3x + 33x = 3x = 1x-intercept: (1, 0) y-intercept: set x = 0 and solve for yy = -3(0) + 3y = 3y-intercept: (0,3) y=0,5x-1Is this two equations? The line y=0 has y-intercept at (0,0)The x-intercept is the entire x-axis y=5x-1x -intercept: Set y = 0 and solve for x y-intercept: Set x = 0 and solve for y

Solve For H ---I> A=1/2(B₁+B₂)h

Alex

Answer:

h = 2A/(B₁+B₂)

Step-by-step explanation:

Given equation

A=1/2(B₁+B₂)h

Solving for h

A=1/2(B₁+B₂)h
2A = (B₁+B₂)h
2A/(B₁+B₂)= h
h = 2A/(B₁+B₂)

Can someone please help I need a clear explanation on how to solve this equation.

nikitadnepr [17]

B = amount of students who chose Bulldog

n = amount of students who chose lion

t = amount of students who chose tiger

so.. "t" chose tiger, ok

"Four times as many students chose Bulldog as chose Tiger"
namely, if "t" chose tiger, then 4 times that many chose Bulldog, thus

b = 4t

"Twice as many students chose Lion as chose Tiger"
namely, if "t" students chose tiger, twice as many chose lion

n = 2t

now, we know a total of 273 students were surveyed, thus

 $\bf \begin{cases}
b+n+t=273\\
\boxed{4t}+\boxed{2t}+t=273
\end{cases}
\\\\\\
7t=273\implies t=\cfrac{273}{7}\impliedby \textit{that many chose \underline{tiger}}$
