X=6 or x=0 that should be it if you wanna do it on your own next time just substitute the numbers

Solve for x.

aivan3 [116]

X^3 = 216

by taking cubic root for both sides

$\sqrt[3]{x^3} = \sqrt[3]{216}$

x = 6

Answer:

$\fbox {x-intercepts : (1, 0) and (-3, 0)}$

$\fbox {Roots : x = 1, x = -3}$

Step-by-step explanation:

Given :

y = 4x² + 8x - 12

4 cancels throughout.

y = x² + 2x - 4

Solving by quadratic formula :

x = -8 ± √(8)² - 4(4)(-12) / 8
x = -8 ± √64 + 192 / 8
x = -8 ± √256 / 8
x = -8 ± 16 / 8
x = -1 ± 2
x = 1 and x = -3

∴ Hence, the x-intercepts are (1, 0) and (-3, 0). The roots of the equation are 1 and -3.

How do i do 3 part a ?

WINSTONCH [101]

In general the binomial expansion is

$(a+b)^n = {n \choose 0} a^0 b^n + {n \choose 1} a^1 b^{n-1} + {n \choose 2} a^2 b^{n-2} + ... + {n \choose n} a^n b^0$

So in our case, because we want ascending powers of x we'll write,

$(-3x + 1)^{11} = {11 \choose 0} (-3x)^0 1^{11} + {11 \choose 1} (-3x)^{1} 1^{10} + {11 \choose 2} (-3x)^{2} 1^9 + {11 \choose 3 } (-3x)^3 1^8 + ...$

We need to calculate the binomial coefficients:

${11 \choose 0} = 1$

${11 \choose 1} = 11$

${11 \choose 2} = \dfrac{11 \times 10}{2} = 55$

${11 \choose 3} = \dfrac{11 \times 10 \times 9}{3 \times 2} = 165$

$(-3x+1)^{11} = 1 (-3x)^0 1^{11} + 11(-3x)^{1} 1^{10} + 55 (-3x)^2 1^{9} + 165 (-3x)^3 1^8 + ...$

$(1-3x)^{11} = 1 -33 x + 495 3x^2 - 4455 x^3+ ...$

Solve the equation 1.5y < -6.75

finlep [7]

1.5y < -6.75

First, divide both sides by '1.5'.
$\frac{-6.5}{1.5}$
Second, since 4.5 × 1.5 = 6.5, simplify the fraction to '-4.5'
$y \ \textless \ -4.5$

Answer: y < -4.5
