Answer:
D has the same y-intercept
Step-by-step explanation:
<em>y-intercept of the function in the question is -3.</em>
<u>A) 2/3 x + 3y = -3</u>
<em>Make y the subject</em>
3y = -2/3x-3
y = -2/9-1
<em>The y-intercept is -1; it is not the same.</em>
<u>B) -2/3 x + 3y = 6</u>
<em>Make y the subject</em>
3y = 2/3x + 6
y = 2/9x + 2
<em>The y-intercept is 2; it is not the same.</em>
<u>C) x + 4y = 12</u>
<em>Make y the subject</em>
4y = -x + 12
y = -x + 3
<em>The y-intercept is +3; it is not the same.</em>
D) 6x - 7y = 21
Make y the subject
7y = 6x - 21
y = 6/7x - 3
The y-intercept is -3; it is the same.
Therefore, option D has the same y-intercept as the function given in the question.

-2.6n-0.3
Answer:
x=6, y=-6
Step-by-step explanation:
-4x-2y= -12
4x+8y= -24
comparing both equations and crossing out both 4x we get
6y= -36
y= -36/6
y= -6
now for finding x, take any one of those equations
we'll take 4x+8y= -24 for now other one would work too
4x+8(-6)= -24 (as y= -6)
4x-48= -24
x= 24/4
x= +6

14 + 4=18
Answer:
The expected loss is $6980
Step-by-step explanation:
From the question we are told that
The chance that a customer survives another year is p =0.96
The rate at which the policy is sold is r = $85 per month
The rate at which the policy is sold per year is R = $85 * 12 per year
= $1020 per year
The amount paid the the beneficiaries is $200,000
The expected value of profit/loss for this company is mathematically represented as
substituting values
- $6980
The negative sign shows that it is a loss
