Recognizing the No-Solution Case Algebraically Consider the system of equations:
x2 + y2 = 8
x=3
Solving for one variable:
Work is shown to solve for the system of equations.
Why does the answer for y indicate that the system has
no real-number solutions?
1. Substitute:
(3)2 + y2 = 8
* The solution does not solve for x first.
O The values for y are square roots of negative
numbers.
The values for y have a positive and a negative
value.
O The values for y have square roots.
2. Simplify:
9 + y2 = 8
3. Isolate:
y²=-1
4. Solve fory:
y = -1
No solution

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
