Answer:

10,

Step-by-step explanation:

The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.

The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200

y = √200 = √100√2=10√2

At what point does the line given by the following equation cross the y-axis? y = (6/9)X + 9

Elodia [21]

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{6}{9}$ x + 9 ← is in slope- intercept form

with y- intercept c = 9

then the line crosses the y- axis at (0, 9 )
