Answer:
4x + 2y = 7
Step-by-step explanation:
The standard form equation goes as follows: Ax + By = C
We know what A, B, and C is so all we need to do is fill them in.
Answer:
(a) .55
(b) .08
(c) about 42681 people
Step-by-step explanation:
Statistics!!
(a) .55 = point estimate
The point estimate is the middle of those two values, or the average. (.63+.47) / 2 = .55.
(b) .08 = ME
The margin of error is the difference between the point estimate and the outer values of the interval. .63-.55 = .08
(c) 42681 people
We think that .55 of the population want to add the bike lanes, so .55 * 75783 = 41680.65 ≈ 42681
Answer:
17. z=18
18. n=-15
19. j = -50
20. a=-27
21. h=-15
22. d=.392
Step-by-step explanation:
17. Multiply both sides by 3, then subtract 6 from both sides
18. Multiply both sides of the equation by 2, then add 7
19. Multiply both sides by -4, then subtract 18 from both sides.
20. Add six to both sides, then multiply both sides by 3
21. Subtract 4 from both sides, then multiply both sides by 4
22. Subtract 6.42 from both sides, then divide both sides by -10
5x^3-25x^2+20x
=5x(x^2-5x+4)
