Answer:

y=-1/2x-3

Step-by-step explanation:

Slope-intercept form is y=mx+b.

The slope is equal to rise/run, which you can count here is -1/2 (down one, over two).

The y-intercept is where the line hits the y-axis, which is -3.

So, the answer is y=-1/2x-3.

Answer:

x = 1/4

Step-by-step explanation:

<u>Calculations:</u>

$7(x-3)+3(4-x)=-8$

$7x-21+12-3x=-8$

$4x-9=-8$

$4x=1$

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12

Reika [66]

Answer:

Step-by-step explanation:

Which radian measure is equivalent to −15°? −9π/20 −12/π −20π/9 −π/12

180 degrees = πrad

-15 degrees = x

Cross multiply

180x = -15π

x = -15π/180

x = -π/12

Hence the value of -15 degrees in radians is -π/12

Solve 3x−5 = 9. <br> x = −3 <br> x = 2 <br> x = 7 <br> x = 8

Nina [5.8K]

Solve 3x−5 = 9:

Add 5 to both sides, to isolate 3x on the left side: 3x = 5+9 = 14

Solve this for x: x = 14/3
