Answer:
A.1
Step-by-step explanation:
-x+8>6
Subtract 8 from each side
-x+8-8>6-8
-x > -2
Divide by -1. Remember that flips the inequality
-x/-1 < -2/-1
x<2
The only number that is less than 2 is one so
Step-by-step explanation:
g(x) = ax²+bx+c
g(x)=−3x²−6x+5
a = -3, b= -6, c = 5
since a <0 , the function has only maximum value.
=> g'(x) = 0
-6x -6 = 0
-6x = 6
x = -1
the maximum value => g(-1) =
-3(-1)²-6(-1)+5 = -3+6+5 = 9
the domain : {x | x € Real numbers}
the range : {y| y ≤ 9, y € Real numbers}
the function is increasing for x < -1
the function is decreasing for x > -1
Answer:
v= 3
Step-by-step explanation:
2-11= -9
-3v/ -9
= 3
Equations can have one solution, but inequalities have infinite solutions.
Hope this helps!
2(x+4)=18
2•x + 2•4 = 18
2x + 8 = 18
2x + 8 = 18
