will factor into the following
Set each factor equal to 0:
or
x = +/- 2i x = +/- 6
Answer: 2i, 6, -6
By convention, the first term of a sequence starts with n = 1 instead of n = 0. This is so n = 1 matches with 1st, n = 2 matches with 2nd, and so on.
In contrast, the y intercept always occurs when x = 0. So something like y = 3x+5 has a y intercept of 5 when you plug in x = 0.
An arithmetic sequence like f(n) = 2n+7 has its first term when n = 1. So the first term would be f(1) = 2(1)+7 = 9 instead of 7 as Hank claims.
Answer:
y = -2x + 12
Step-by-step explanation:
Parallel = Same Slope Perpendicular = Opposite Reciprocal of Slope
How to find "b" or y intercept:
y = mx + b (3,6) slope = m: -2
plug in the corresponding values for the variables
6 = -2(3) + b
12 = b
1 one just divide each amount of money by 80 then subtract and boom answer!!!
To find the equation of a line using two given set of points, you must first find slope. To do so, we must use the slope formula:
y2 - y1 / x2 - x1
In this case:
1 - 9 / -1 - 3 = -8 / -4
- 8 / -4 = 2 (simplified)
Now we can use the point-slope formula:
y - y1 = m(x - x1)
y - 1 = 2(x + 1 )
y - 1 = 2x + 2
y = 2x + 3
In order to make 3x - y = 6 in slope intercept form, we must isolate y.
- y = -3x + 6
Note: y cannot be negative, so we'll multiply both sides by -1
( -1 ) - y = - 3x + 6 ( -1 ) = y = 3x -6
