Answer:
{ x | -7 ≤ x ≤ 4 }
Step-by-step explanation:
Answer:
The rectangular form of
is
.
Answer:
4 units
Step-by-step explanation:
Distance like magnitude is simply a positive value
----------------------------
Since the y coordinate is the same
the distance is just the difference in the x coordinates
from -5 to -1 is a distance of 4
So you want to find two numbers that add up to -13 and multiply to
40. You can find the factors of 40 and find the pair that adds up to
-13. -8 and -5 multiply to 40 and add up to -13.
<span><span>(x−5)</span><span>(x−8)</span>=<span>x2</span>−13x+40</span>
You can use foil to test it
<span><span>x2</span>+<span>(−8x)</span>+<span>(−5x)</span>+40=<span>x2</span>−13x+40</span>
<span><span>x2</span>−13x+40=<span>x2</span>−13x+</span>
