Given the equation 2x = 4y - 3 write another linear equation that would create a system that has the number of solutions listed
Harman [31]

Answer:

A. 2x-4y=\pi
B.  x=1

C. 2x-4y=3

Step-by-step explanation:

A. 2x-4y=\pi. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND \pi, or any number you like. But yesterday was 3/14 so let's pick a fun number!

B.  x=1 Or y=1. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind

C. 2x-4y=3. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.

A wheel initially has an angular velocity of 18 rad/s, but it is slowing at a constant rate of 2 rad/s 2 . By the time it stops,
Kaylis [27]

Answer:13 revolution

Step-by-step explanation:

Given  data

Wheel initial angular velocity\left ( \omega \right )=18 rad/s

Contant angular deaaceleration\left ( \alpha \right )=2rad/s^2

Time required to stop wheel completely=t sec

\omega =\omega_0 + \aplha t

0 =18 +\left ( -2\right )t

t=9 sec

Therefore angle turn in 9 sec

\theta=\omega_{0} t+\frac{1}{2}\left ( \alpha\right )t^{2}

\theta=18\times 9+\frac{1}{2}\left ( -2\right )\left ( 9\right )^2

\theta=81rad

therefore no of turns(n) =\frac{81}{2\times \pi}

n=12.889\approx13 revolution

Showing algebraic support, find the value of x.
Travka [436]

Answer:

x = 52.5

Step-by-step explanation:

The triangle on the left has 2 congruent sides, thus is isosceles

The base angles of an isosceles triangle are also congruent, thus

x = \frac{180-75}{2} = \frac{105}{2} = 52.5
