Is this from k12? i am a k12 student, and the answer should be 2.2 units but I could be wrong.
Answer:
C, D, J
Step-by-step explanation:
Points to the left of the y-axis have a negative x- value
Points to the right of the y-axis have a positive x- value
Points on the y-axis have an x- value of zero
C(- 4, 5), D(- 9, 9 ), J(- 9, 0) ← are the coordinates of the points
All have a negative x- value
Answer:
(42, 0)
Step-by-step explanation:
Since we know the slope and y-intercept we can write the equation of the line in slope-intercept form which is y = mx + b; therefore, the equation is y = -3/7x + 18. To find the x-intercept, we just plug in y = 0 which becomes:
0 = -3/7x + 18
-18 = -3/7x
x = 42
You can use a square plus b square equal C square to fijd each length . or you can memorize the special triangles or you can also do proportional problem. it all works
