Lostsunrise [7]3 years ago
7 0

Answer:

4(X+2Y)

Step-by-step explanation:

Rearrange the equation:

X+3X+Y+7Y

Combine like terms (so add coefficients of like variables):

4X+8Y

Factor if necessary:

4(X+2Y)

A mass oscillating up and down on the bottom of a spring (assuming perfect elasticity and no friction or air resistance) can be
alexdok [17]

The motion of the mass as it moves on the bottom of the spring is a

repetitive motion.

  • \mathrm{The \ motion \ of \ the \ mass \ attached \ to \ the \ spring \ is \ }\displaystyle d = 6 \cdot sin\left(\frac{\pi}{2} \cdot t \right)

Reasons:

The general form of the equation of the simple harmonic motion of the

mass is <em>d</em> = a·sin(ω·t)

Where;

d = The distance of the mass from the rest position

a = The maximum displacement of the mass from the equilibrium position = 6 cm

ω = The frequency of rotation

t = The time of motion

ω = The frequency of rotation

\displaystyle \omega = \mathbf{\frac{2 \cdot \pi}{T}}

Where;

T = The time to complete one cycle (the period of oscillation) = 4 seconds

\displaystyle \omega = \frac{2 \cdot \pi}{4} = \frac{\pi}{2}

Combining the above values gives the modelling equation as follows;

\displaystyle d = 6 \cdot sin\left(\frac{\pi}{2} \cdot t \right)

How do I solve this ?
erica [24]
4x+3y=10
You want to isolate the y so subtract 4x from each side

3y=-4x+10
You want to isolate the y so divide everything by 3

y=-(4/3)x+(10/3)
That’s what y is

Use the LCD to rewrite the 1/6 and 3/8 with the same denominator.
oee [108]

Answer:

1/6 becomes 4/24 and 3/8 becomes 9/24.

Step-by-step explanation:

The LCD of the denominators is 24 because that is the lowest number that 6 and 8 are both related too (6 times 4 is 24, and 8 times three is 24). Since 6 goes into 24 4 times, multiply 1 (the numerator) by 4 and you get 4. Since 8 goes into 24 3 times, multiply 3 (the numerator) by 3 and you get 9.
