Let’s find the scale factor (the number each number on the left has been multiplied by)
14/10 = 1.4
The scale factor is 1.4 so 10 has been multiplied by 1.4 to get 14

so you are now going to do 1.4 * 4 = 5.6

5.6 is your answer!!

NeX [460]

Answer:

The zoo will cost more money for a group of 12 students to visit.

Step-by-step explanation:

First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.

Science Center: $36.76 ÷ 3 = $12.25

Zoo: $51 ÷ 4 = $12.75

Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.

Science Center: $12.25 x 12 = $147.04

Zoo: $12.75 x 12 = $153

Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.

Solve for x and y 1/(x+yi) + 2/(x-yi) = 1+i
aliina [53]

Answer:

Step-by-step explanation:

x+i*y≠0 ==> x≠0 and y≠0

x-i*y≠0 ==> x≠0 and y≠0

We must exclude (0,0) as solution.

\dfrac{1}{x+i*y} +\dfrac{2}{x-i*y} =1+i\\\\\dfrac{1*(x-i*y)}{(x+i*y)(x-i*y)} +\dfrac{2*(x+i*y)}{(x-i*y)(x+i*y)} =1+i\\\\\\\dfrac{x-i*y+2x+2i*y}{x^2+y^2} =1+i\\\\3x+i*y=(1+i)(x^2+y^2)\\\\3x+i*y=(x^2+y^2)+i(x^2+y^2+i*(x^2+y^2)\\\\\left\{\begin{array}{ccc}3x&=&x^2+y^2\\y&=&x^2+y^2\\\end {array}\right.\\\\\\\left\{\begin{array}{ccc}y&=&3x\\3x&=&x^2+9x^2\\\end {array}\right.\\\\\\\left\{\begin{array}{ccc}y&=&3x\\x(10x-3)&=&0\\\end {array}\right.\\\\

\left\{\begin{array}{ccc}x&=&0\\y&=&0\\\end {array}\right.\ (to\ exclude) \ or \ \left\{\begin{array}{ccc}x&=&\dfrac{3}{10}\\\\y&=&\dfrac{9}{10}\\\end {array}\right.\\\\Sol=\{(\dfrac{3}{10},\dfrac{9}{10})\}\\
