1 = x^2 - x
x^2-x-1=0
quadratic formula:

the positive root is special because it's equal to the
golden ratio
Answer:
30:54
Step-by-step explanation:
5x6=30 and 9x6=54 and because I took the test on edge
Answer:
No
Step-by-step explanation:
When there are two or more points on the same vertical line, the relation shown is <em>not a function</em>.
Graph 1 has two points at x=-4.
Graph 2 has two points at x=4.
Neither shows a relation that is a function.
Answer:
Below in bold.
Step-by-step explanation:
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
y - (-1)) = -2/5(x - -10)
y + 1 = -2/5(x + 10)
y + 1 = -2/5x - 4
y = -2/5x - 5.
In standard form this is:
2x + 5y = -25.
Answer:
1. 180
2. 300
3. 480
Step-by-step explanation:
1. Since 30% of 600 (or 0.3 * 600) = 180, the 1st blank is 180.
2. 50% of 600 (also easy to just think of one half {1/2}) = 300
3. Because 180 + 300 = 480
hope this helps:)
