Which equation represents a line that is parallel to the line y=3-2x?
dlinn [17]

Answer:

(1)

Step-by-step explanation:

Slope of the given line is -2

1) 4x + 2y = 5, 2y = -4x + 5, y = -2x + 5/2, slope is -2

Parallel line, same slope so the answer is (1)

Select the best possible first step to solving the system by first eliminating the x variable.
ipn [44]
The best possible first step would be to multiply equation one by 4 and equation by 5 that would eliminate the y and allow you to solve for x.

In essence,      4 × (3x  +  5y = 1)   eq1
                        5 × (2x + 4y = -4)    eq2
 
   thus giving rise to  12x + 20y = 4     eq1 × 4
                                  10x +20y = -20  eq2 × 5

You can then just subtract one equation from the other
For example,   (12x + 20y = 4) - ( 10x +20y = -20 ) 

                        12x - 10x + 20y - 20y = 4 - (-20) 
                                                      2x = 24
                                                        x = 12

What is the arc length when theta=pie/3 and the radius is 5 cm
Jobisdone [24]

Answer:

Hey There!

Let's solve....

Radius=5cm

Angle = pi/3

Therefore arc length= Radius×angle

= 5 \times  \frac{\pi}{3} \\  \\  let \:  \pi \: be \: 3.14cm \: so \: \\  \\ 5 \times  \frac{3.14}{3}  \\  \\  =  \frac{15.70}{3}  \\  \\  = 5.23cm

The arc length is 5.23 cm when Theta=pi/ 3 and radius is 5 cm.
