Answer:
there's only one graph that I see so please take a better picture so therefore I can see the whole option choices to help you
Step-by-step explanation:
Answer:
<u>A = x² - 5x - 8</u>
Step-by-step explanation:
<u>Finding x</u>
- Area (deck) = Area (Rectangle) - [Area (bench) + Area (planter)]
- A = x(x - 4) - [ 2(6) + 1/2(2)(x - 4) ]
- A = x(x - 4) - [12 + x - 4]
- A = x² - 4x - 8 - x
- <u>A = x² - 5x - 8</u>
No. For two lines to be perpendicular their slope must be the negative reciprocals of one another, mathematically:
m1*m2=-1
So if the slope of one line is negative, the line perpendicular to this must be positive by definition.
