Answer:
turning point: (-3 , -16)
Step-by-step explanation:
y = x² + ax + b pass(0,-7)(7,0)
(0)² + 0*a + b = -7 b= -7
(7)² + 7*a - 7 = 0 7a = 42 a = 6
y = x² + ax + b = y = x² + 6x - 7 = (x+3)² - 16
(h,k): vertex equation: y = a(x-h)² + k
h = -3 k=-16
Answer:
x=23
Step-by-step explanation:
First you need to set up the equation:
9 + (x + 3) = 35
Then you need to add 9 and 3
x + 12 = 35
x = 35 - 12, x = 23

Answer:
x ≥ 10
Step-by-step explanation:
Note:- (Let's take temperature as "x")
At least sign "≥"
I hope it helps.
To be honest I’m not sure but I believe it’s -7 if there’s anymore information please attach it along with your question
