Step-by-step explanation:
y=6+4x, as equation (iii)
=> -5x-(6+4x)=21
=> -5x-6-4x=21
=> -5x-4x-6=21
=> -9x-6=21
=> -9x=21+6
=> -9x=27
x= -3, by dividing both sides by -9
So, by inserting x in the first equation,
=> -4(-3)+y=6
=> 12+y=6
=> y=6-12
=> y= -6.
Therefore, x= -3 and y= -6
Answer:
1.7 units
Explanation:
The length of an arc is calculated using the formula below:

Substitute the given values of θ and r:

The length of the arc is 1.7 units.
The numbers are divisible by 2 are 12 and 412
We are given with the best fit line
<span>y = 2,500x - 2,500
The y-intercept is -2500
and the slope is 2500
This line can be translated into the following statements:
At the start of the operations, there is a negative profit of -2500. Each year, the profit increases by 2500</span><span />
