Answer:

x=-7

Step-by-step explanation:

9x + 16 = 4x - 19

Subtract 4x from each side

9x-4x + 16 = 4x-4x - 19

5x+16 = -19

Subtract 16 from each side

5x+16 -16 = -19-16

5x = -35

Divide each side by 5

5x/5 = -35/5

x = -7

Answer:

x = -7

Step-by-step explanation:

<h2><u>solve</u></h2>

in order to solve this , make x the subject of formula:

9x + 16 = 4x - 19

9x + 16 - 4x = -16

5x = -19 - 16

5x =-35

x = -35 / 5

<h3><u>x = -7 </u></h3>

Which Value From The Number Set 1,3,5,7 Makes The Inequality X+5&gt;10 True
Ne4ueva [31]
Put all number choices in for x. 1+5=6, 3+5=8, 5+5=10, 7+5=12. The equation says that the answer has to be greater than ten. 6 and 8 are less than ten, and ten is equal to ten, so the only answer is 7, because 7+5=12 :)

Write the equation of the line that is parallel to the line y=-3x+2 and goes through the point (2,-1)
pashok25 [27]

9514 1404 393

Answer:

  y = -3x +5

Step-by-step explanation:

The parallel line will have the same slope: m = -3.

The new y-intercept is ...

  b = y -mx

  y = -1 -(-3)(2) = -1 +6 = 5

Then the equation of the parallel line through (2, -1) is ...

  y = -3x +5

MA_775_DIABLO [31]

9514 1404 393

Answer:

  30°

Step-by-step explanation:

The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:

  Sin = Opposite/Hypotenuse

For a ramp 1 m high and 2 m long, we have ...

  sin(x) = (1 m)/(2 m) = 1/2

  x = arcsin(1/2) = 30°

The elevation angle of the ramp needs to be 30°.
