21. Definition of an altitude
Answer:
16
Step-by-step explanation:
40 = 3:2 x
Then, you know that 3+2 = 5
so, x = 40/5
x=8
Now, you multiply x by 2 to get 16
16
Answer:
See below in bold.
Step-by-step explanation:
3y - 2x = 9
3y = 2x + 9 Divide through by 3:
y = 2/3x + 3 is the slope-intercept form.
The y intercept is when x = 0:
y = 2/3(0) + 3
= 3.
The y-intercept is at (0, 3).
4 divided by 3/4 is equivalent to 4 times 4/3 which is equal to 16/3 or 5 1/3
