Answer:
$1719.55, 61.4%
Step-by-step explanation:
Original price of stove: $2,800
Value of stove after 1 year: (1 - 0.15)($2,800), or 0.85($2,800) = $2,380
Value of stove after 2 years: 0.85($2,380) = $1719.55
Find the ratio of this last result to the original price and convert that to a percentage:
$1,719.55
-------------- = 0.614, or approximately 61.4%
$2,800
It should be noted that the value of y for the expression for -15y -40 is y = 2.67.
<h3>How to illustrate the information?</h3>
It should be noted that an expression in mathematics simply means the sentence with a minimum of two variables or numbers and at least a mathematical operation.
It should be noted that based on the information, we want to solve the expression which is illustrated as:
-15y -40
Equate the expression to 0
-15y - 40 = 0
-15y = 40
Divide through by -15
-15y/-15 = 40/15
y = 2.67
Therefore, it should be noted that the value of y for the expression for -15y -40 is y = 2.67.

Solve the expression for -15y -40
Answer:
No solution
Step-by-step explanation:
If we substitute the y into the equation, we get 9x+3(-3x+4)=-7
If we distribute the 3, we get 9x-9x+12=-7
This then cancels out both 9x's and we are left with 12=-7, making it no solution.
slope is zero for both of them. Why?
Since slope, m = rise/run
which is m = (y2-y1)/(x2-x1)
since y2-y1 is zero for both cases and zero divided by any number is zero therefore the slope is zero for both. hope this helps!
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!
