Answer: x=15

Move all terms containing x to the left, all other terms to the right

<u>Add 18 to each side of the equation</u>

<u></u>-18 + 18 + x = -3 + 18<u></u>

<u></u>

<u>Combine like terms: -18 + 18 = 0 </u>

<u></u>0 + x = -3 + 18\\x = -3 + 18<u></u>

<u></u>

<u>Combine like terms: -3 + 18 = 15 </u>

<u></u>x=15<u></u>

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,
Maurinko [17]

We have been given a system of equations y=\frac{1}{2}x-4 and y=-2x-9. We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

\frac{1}{2}x-4=-2x-9

\frac{1}{2}x-4+4=-2x-9+4

\frac{1}{2}x=-2x-5

\frac{1}{2}x+2x=-2x+2x-5

\frac{1}{2}x+\frac{4}{2}x=-5

\frac{1+4}{2}x=-5

\frac{5}{2}x=-5

\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}

x=-2

Upon substituting x=-2 in equation y=-2x-9, we will get:

y=-2(-2)-9

y=4-9

y=-5

Therefore, the solution of our given system of equations would be (-2,-5) and option A is the correct choice.

melomori [17]

9514 1404 393

Answer:

  45°, 135°

Step-by-step explanation:

The total of the two angles is 1+3 = 4 times the smaller angle. The total is 180°, so the smaller angle is

  180°/4 = 45°

The larger angle is 3×45° = 135°

The two angles are 45° and 135°.
