PLS HELP !!! U WILL GET 13 POINTS AND BRAINLIEST !!THIS IS A TEST AND I NEED TO SHOW WORK PLS PLS HELP AND ONLY ANSWER IF U KNOW
erastova [34]

Answer:

This should be parallel.

Step-by-step explanation:

Two lines are said to be parallel only if their slope matches. They are said to be perpendicular only if the slopes are negative reciprocals.

Here, you should put both equations in slope intercept form which is y=mx+b. The letter "M" represents the slope of both equations.

2y-6=3x+4 turns into 2y=3x+10 after adding 6 and into y=3/2x+5 after dividing the equation by 2. The slope for this equation is 3/2.

8y=12x+8 must be divided by 8 to be in slope intercept form. This equation becomes y=3/2x+1. Here the slope is also 3/2.

The slopes for each equation match making these lines parallel.

Answer:

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13     x = 13

   cos45 = 13/y     y = 13√2

12) sin30 = 4/x      x = 8

     tan30 = 4/y     y = 4√3

13) sin60 = 21/x    x = 21(2/√3) = 42/√3

    y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22   x = 22/√2

     sin45 = y/22   y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x   x = 12/√2

tan45 = y/12      y = 12

cos30 = z/24    z = 24(√(3)/2) = 12/√3
