Answer:
3) The function's leading coefficient is negative.
Explanation:
(1) Is not the answer because when x = 3, f(x) = 0.
(2) Is not the answer because when f(x) = -3,
x = 0.
(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.
Therefore,
(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.
I hope this helped! :)
Answer: b = -20
Step-by-step explanation: I have difficulty reading the table of values of (x,y). I picked just the first (10, -120) to calculate b.
y = -10x + b
-120 = -10(10) + b
b = -20
That should work for all the points:
(20, -220) : -220 = -10(20)-20 - Yes, etc.
But the values towards the end of the table don't makes sense/don't work. (0, -2)????
Answer:
x = 6
Step-by-step explanation:
If A, B and C lies on a straight line in order, then;
AB+BC = AC
x+12+2x-4 = 26
x+2x+12-4 =26
3x+8 = 26
3x = 26-8
3x = 18
x = 18/3
x = 6
Hence the value of x is 6
