Answer:

D.

Step-by-step explanation:

cos is positive and sin is negative

=>

it must be in quadrant IV.

you remember, 1 = sin² + cos²

1 = sin² + (3/5)² = sin² + 9/25

25/25 = sin² + 9/25

16/25 = sin²

sin = 4/5 or -4/5

and as sin of this angle is < 0, our solution is -4/5

Solve |2x - 1| + 3 = 6.
umka21 [38]

Answer:

x =2                         x = -1

Step-by-step explanation:

|2x - 1| + 3 = 6.

Subtract 3 from each side

|2x - 1| + 3-3 = 6-3

|2x - 1|= 3

An absolute value has two solutions, one positive and one negative

2x-1 =3                   2x -1 = -3

Add 1 to all sides

2x-1+1 =3+1             2x-1+1 = -3+1

2x = 4                      2x =-2

Divide by 2

2x/2 = 4/2                 2x/2 = -2/2

x =2                         x = -1

2. Perpendicular to y=1/2x -6 that passes through (6,-4) <br> PLEASE HELP ME ASAP
iren [92.7K]

Answer:

To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

n = \frac{-b}{a}

Then we just plug in the point we want to cross and solve for the constant.

Step-by-step explanation:

we see that m = \frac{1}{2}

so, n = -\frac{2}{1} = -2

now we have the equation

-2x + b = y

plugging in (6, -4) we get

-2(6) + b = -4\\-12+b = 4\\b=4+12=16

This gives us our function

y = -2x + 16
