This doesn't really make sense,but this is what I got
It is 900,000 it is in the hundreds thousandths place.
Answer:
a = 1
b = -3
c = -2
Step-by-step explanation:
Answer:
The value of f(-3) = -3
Step-by-step explanation:
It is given that f(x) = 3(x+2), in order to find f(-3), we have to substitute x = -3 into the function, f(x) :
f(x) = 3(x+2)
f(-3) = 3(-3+2)
= 3(-1)
= -3
Answer:
y = 6x² -13x -5
Step-by-step explanation:
(1,-12) (2,-7) (5,80)
y = ax² + bx + c
-12 = a*1² + b*1 + c = a+b+c (1)
-7 = 4a + 2b + c (2)
80 = 25a + 5b + c (3)
(2)-(1): 3a + b = 5 (4)
(3)-(2): 21a + 3b = 87 (5)
(4)*3: 9a + 3b = 15 (6)
(5)-(6): 12a = 72 a = 6
(4) b = -13
(2) c = -5
