Answer:
y=-4x^2+9x+9
Step-by-step explanation:
1st: we assume the equation will be in standard form (ax^2+bx+c)
2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.
3rd: since it passes through (2,11) then 11=4a+2b+c
4th: since it also passes through (3,0) then 0=9a+3b+c
* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*
So a=-4, b=9, c=9
plug in the numbers and you get y= 4x^2+9x+9
Hope this helps you. :3
The algebraic expression you would write is 12v
Step-by-step explanation:
3y + 2x - 10 = 0
in standard form
2x + 3y -10=0
||
as (ax + by - c = 0)
m = -a/b
= -2/3
or
3y + 2x - 10 = 0
make y subject
y = -2/3x + 10/3
The answer is C! 6/7 because the negatives cancel out!
1st pic
answer
D. Yes. triangle JKL similar to triangle STV. SF is 6
----------
2nd pic
answer is A.
No because length of corresponding sides are not proportional
--------------
3rd pic
34/17 = 12
so
x = 30/2 = 15
y = 16/2 = 8
answer
x = 15
y = 8
--------------
4th pic
28/14 = 2
so
x = 42/2 = 21
y = 56/2 = 28
z = 42/2 = 21
answer
x = 21
y = 28
z = 21
