Answer: 3
Step-by-step explanation:
12C - 4 = 14C - 10
12C - 14C = - 10 + 4
- 2C = - 6
C = <u>- 6</u>
-2
C = 3
Answer:
i’m not sure good luck
Step-by-step explanation:
X<2: 5x+7>17 you subtract seven from both sides to give you 5x>10 when you divide by 5 the sign flips to give you x<2.
Equation of the parabola: y = ax^2 + bx + c. Find a, b, and c.
x of axis of symmetry:
x
=
−
b
2
a
=
3
-> b = -6a
Writing that the graph passing at point (1, 0) and point (4, -3):
(1) 0 = a + b + c -> c = - a - b = - a + 6a = 5a
(2) -3 = 16a + 4b + c --> -3 = 16a - 24a + 5a = -3a --> a = 1
b = -6a = -6; and c = 5a = 5
y
=
x
2
−
6
x
+
5
Check with x = 1: -> y = 1 - 6 + 5 = 0. OK
