y-5=(-4/3)(x+6)
y=(-4/3)x-8+5
y=-4x/3 - 3
Answer:
x=a, 2a −(1+a 2 )
Step-by-step explanation:
Given, (1−a 2 )(x+a)−2a(1−x 2 )=0 x+a−a 2 x−a 3 −2a+2ax 2 =0 x−a−a 2 x−a 3 +2ax 2 =0 2ax 2 +x(1−a 2 )−(a+a 3 )=0 By using formula, we have x= 2(2a) −(1−a 2 )± (1−a 2 ) 2 −4(2a)[−(a+a 3 )] = 4a −(1−a 2 )± (1+3a 2 ) 2 = 4a −(1−a 2 )±(1+3a 2 ) = 4a −1+a 2 +1+3a 2 ; 4a −1+a 2 −1−3a 2 = 4a 4a 2 ; 4a −2−2a 2 =a; 2a −(1+a 2 )

Friday $26
Saturday $22
Answer:
$26
Step-by-step explanation:
For 7 days, given an average of 19 then it means the total is 7*19=$133
For the given 6 days, then the sum is equal to 12+14+17+16+26+22=$107
The difference between the sum of 6 and the value for average will be 133-107=$26
Therefore, to get the average given value, then the value for Sunday must be equal to $26
Answer:
Step-by-step explanation:
Step 1: Solve one of the equations for one of the variables.
Step 2: Substitute that equation into the other equation, and solve for x.
Step 3: Substitute x values into one of the original equations, and solve for y.
Answer:
$400
Step-by-step explanation:
Given that:
Earnings per week for Amber = $200
Total increase in the salary as per Amber's hard work = 100%
To find:
Earnings of Amber now?
Solution:
We are given the initial salary and its percentage increase.
We have to find the increased value of salary.
Increase in the salary = 100% of $200
Amber's Current salary = Initial salary + Increase in the salary
Putting the values of the initial salary and increase in the salary:
Amber's Current salary = $200 + $200 = <em>$400</em>
