Which of the following are solutions to the equation below?

Zarrin [17]

Answer:

D, E

Step-by-step explanation:

(4x - 1) ^2 = 11 => (take square roots of both sides)

4x - 1 = +\- sqrt(11) => (Add 1 to both sides)

4x - 1 + 1 = 1 +\-sqrt(11) =>

4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)

x = ( 1 +\- sqrt(11) ) /4

Which are choices D and E

Find the measurement of x

3241004551 [841]

$\\ \sf\longmapsto 15(x+1)=150$

$\\ \sf\longmapsto x+1=\dfrac{150}{15}$

$\\ \sf\longmapsto x+1=10$

$\\ \sf\longmapsto x=10-1$

$\\ \sf\longmapsto x=9$

Make denomenators the same
common denom is 2n²

multiply 3/2n by n/n
mulitply 1/n² by 2/2

we get
$\frac{3n}{2n^2}+\frac{2}{2n^2}=\frac{n-2}{2n^2}$
combine fractions
$\frac{3n+2}{2n^2}=\frac{n-2}{2n^2}$
multiply both sides by 2n²
2n+2=n-2
minus n both sides
n+2=-2
minus 2 both sides
n=-4

Find (fog)(x) and (gof)(x) f(x) = 8x-5, g(x) = 10 - 2x help please

igomit [66]

Answer:

$(fog)(x) = f( \: g(x) \: ) \\ = 8(10 - 2x) - 5 \\ = 80 - 16x - 5 \\ = - 16x + 75$

$(gof)(x) = g( \: f(x) \: ) \\ = 10 - 2(8x - 5) \\ = 10 - 16x + 10 \\ = - 16x + 20$

I hope I helped you^_^
