I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.
The answer or range would be 40
Xy = 8
x + y = 6
x + y = 6
x - x + y = -x + 6
y = -x + 6
xy = 8
x(-x + 6) = 8
x(-x) + x(6) = 8
-x² + 6x = 8
-x² + 6x - 8 = 0
-1(x²) - 1(-6x) - 1(8) = 0
-1(x² - 6x + 8) = 0
-1 -1
x² - 6x + 8 = 0
x² - 4x - 2x + 8 = 0
x(x) - x(4) - 2(x) + 2(4) = 0
x(x - 4) - 2(x - 4) = 0
(x - 2)(x - 4) = 0
x - 2 = 0 or x - 4 = 0
+ 2 + 2 + 4 + 4
x = 2 or x = 4
x + y = 6
2 + y = 6
- 2 - 2
y = 4
(x, y) = (2, 4)
or
x + y = 6
4 + y = 6
- 4 - 4
y = 2
(x, y) = (4, 2)
The two numbers that add up to 6 and multiply to 8 are 4 and 2.
Answer:
skin cells were not burned.
Step-by-step explanation:
<h3><u>
The complete exercise is: Two percent of Sennie's skin cells were burned when she escaped from a fire. If
of her skin cells were burned then, how many skin cells were not burned?</u></h3><h3 />
Let be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.
According the the data given in the exercise, you know that 2% represents
of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:

With this information you can write the following proportion:

Solving for "x", you get:

To express the result in Scientific notation, the decimal point must be after the first digit; then you must move the decimal point two places to the left:
