Answer: x = 20.

Step-by-step explanation:

x and (3x + 10) combine to form a right angle, shown in the diagram by the small square joining the perpendicular lines.

Right angles are 90 degrees, so you can add both angles to get 90:

x + (3x + 10) = 90\\\\4x + 10 = 90\\\\4x = 80\\\\x = 20

Whats a line passing<br> through the<br> points (0, 0) and<br> (5,-7)?
Ipatiy [6.2K]

Answer:

y = -7/5x

Step-by-step explanation:

First, we need to use the two points to find the slope.

m = y₁ - y₂ / x₁ - x₂

m = -7 - 0 / 5 - 0

m = -7/5

Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.

y - y₁ = m(x - x₁)

y - (-7) = -7/5(x - 5)

y + 7 = -7/5x + 7

y = -7/5x

Therefore, the equation of the line is y = -7/5x.
