Answer:
You could use a graphing calculator to see the lowest point in the graph OR you could put that equation into it's completed squared form, which is (x-4)^2 -4. The opposite of -4 in the parentheses is positive 4, and the leftover -4 is the y value. So that also becomes (4,-4)
Answer:
0
Step-by-step explanation:
Plug in the corresponding numbers to the corresponding variables. Note that:
y = 9
z = 0
Plug in 9 for y, 0 for z.
(2z)/y = (2(0)/(9) = (0)/9 = 0
0 is your answer.
~
since triangles are similar
=》 21/9 = x/3
=》 x = 21×3/9 =7
