The goal is to compare the fractions with the same denominator.

Find the LCD

6 × 2 = 12, 6 × 3 = 18

9 × 2 = 18

LCD = 18

$\frac{5}{6} = \frac{15}{18} 
$

$\frac{7}{9} = \frac{14}{18}$

Dan has more pocket money remaining, because $\frac{7}{9}$ is smaller than $\frac{5}{6}$ .

What is the radian value of arccos(-3/sqrt(2))?

Ksju [112]

Answer:

Not defined over the real numbers

Step-by-step explanation:

Let

$x = arc \cos( \frac{ - 3}{ \sqrt{2} })$

This implies that:

$\cos(x) = \frac{ - 3}{ \sqrt{2} }$

This implies that:

$\cos(x) = - 2.12$

The range of the cosine function is -1≤y≤1

Therefore

$arc \cos( \frac{ - 3}{ \sqrt{2} })$

is not defined for over the real numbers.

The largest doll is 12 inches tall. the height of each of the other dolls is 710710 the height of the next larger doll. write an

GrogVix [38]

the question doesn't say how many dolls. there would be an infinite number.
But we'll just form the equation for the nth doll.
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7

OK, We now see the pattern. Each successive doll is mult by the previous

doll height x 0.7
the Nth doll, 12 is mult by 0.7(n-1)
So, the height of the nth doll can be expressed as: 12 x 0.7(n-1)
example: 4th doll = 12 x 0.7(4-1) = 12 x 0.73
10th doll = 12 x 0.7(10-1) = 12 x 0.79 etc

Which system of equations below has infinitely many solutions? y = –3x 4 and y = –3x – 4 y = –3x 4 and 3y = –9x 12 y = –3x 4 and

Flura [38]

the equations y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions. option B is correct.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Condition for the parallel lines.

L1, ax + bx + c = 0

L2, dx + ey + f = 0

If $\rm \dfrac{a}{d} = \dfrac{b}{e} = \dfrac{c}{f}$ then lines have infinitely many solutions.

<h3>Which system of equations below has infinitely many solutions?</h3>

y = –3x + 4 and 3y = –9x + 12

On comparing we have

a = -3 , b = 1, and c = 4

d = -9 , e = 3, and f = 12

Then their ratio will be

$\rm \dfrac{1}{3} = \dfrac{-3}{-9} = \dfrac{4}{12}\\\\\rm \dfrac{1}{3} = \dfrac{1}{3} = \dfrac{1}{3}$

Hence y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.

Thus the option B is correct.
