Answer:

(2x -3)

Step-by-step explanation:

If you assume that the result is a binomial, you can find the terms of it from ...

(8x^2)/(4x) + (3)/(-1) = (2x -3)

As a check, you can multiply it out.

(2x -3)(4x -1)/(4x -1) = (8x^2 -14x +3)/(4x -1) . . . . as required

The quotient is (2x -3).

Robert threw a rock off a bridge into the river. The distance from the rock to the river is modeled by the equation h=-16ť – 16t

cluponka [151]

Answer:

1.5 seconds

Step-by-step explanation:

h=-16t² – 16t+ 60

When the rock enter the water, the height is 0. ... h=0

0 = -16t² – 16t+ 60 = -4 * (4t² - 4t +15) = -4* (2t - 3) (2t +5)

2t-3=0 or 2t+5 = 0

t = 3/2 or t = -5/2 (time can't be negative)

t = 3/2 or 1.5

Help me find x please

Sedaia [141]

Answer:

$\displaystyle 13 = x$

Step-by-step explanation:

All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:

60° = [8x - 44]°

+ 44° + 44°

____________

$\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x$

Let A {x ∈ N : 3 ≤ x ≤ 13}, B {x ∈ N : x is even}, and C {x ∈ N : x is odd}.

murzikaleks [220]

Answer: The answer is as follows:

Step-by-step explanation:

From the given information, we have

Let A {x ∈ N : 3 ≤ x ≤ 13}, B {x ∈ N : x is even}, and C {x ∈ N : x is odd}

A = {3,4,5,6,7,8,9,10,11,12,13}

B = {2,4,6,8,10,12,14,..........,....}

C = {1,3,5,7,9,11,13,15,17,...........,}

(a) A∩B = {4,6,8,10,12}

(b) A∪B = {3,5,7,9,11,13 and x ∈ N : x is even}

(d) B∪C = { x ∈ N : x is even and x ∈ N : x is odd}

Example of sets A and B when A ∩ B = {3, 5} and A ∪ B = {2, 3, 5, 7, 8}

A = {2,3,5,7,8} and B = {3,5}
