Answer:
x = 9, x = -9
alternatively:
x = {9, -9}
Step-by-step explanation:
how absolute value works is you split it into 2 equations:
9x = 81, and 9x = -81
9x = 81
x = 81/9
x = 9
9x = -81
x = -81/9
x = -9
Answer:
y = -4x + 15
Step-by-step explanation:
Slope-intercept form is y = mx + b
m = slope ()
b = y-intercept (where the line crosses the y-axis)
It doesn't matter which coordinate pair you use for (x₁,y₁).
(x₁,y₁) = (2,7)
(x₂,y₂) = (4,-1)
Simplify
Simplify
-4 = your slope (m)
To get this information into slope-intercept form, you have to plug it into point-slope form, y - y₁ = m(x - x₁). It doesn't matter which coordinate pair you use for (x₁,y₁).
y - y₁ = m(x - x₁) Let's use (2,7) since it doesn't have negatives.
y - 7 = -4 (x - 2) Distribute
y - 7 = -4x + 8 Add 7 to both sides
y = -4x + 15
Check your answer by plugging both coordinate pairs in.
y = -4x + 15
7 = -4(2) + 15
7 = -8 + 15
7 = 7
and
-1 = -4(4) + 15
-1 = -16 + 15
-1 = -1

Given
--- For the forest
-- --- For the forest
Required
Determine the area of the habitat
Since the distance between the animal's habitat is x mi on both sides;
The length and width of the habitat is:
The area is then calculated as follows;
Expand
Open Brackets
Reorder
Hence; the required polynomial for the habitat area is:
B) 18
