Answer:
Should be 1 if im not wrong Then Mark Me brainliest
Step-by-step explanation:
a negative times a neg equals a posative
Neg x pos = neg
pos x neg = neg
pos x pos = pos
neg x neg = pos
so if there greater then over neg<, >,=
You would look at the problem for given f(x)=
x → -1 and neg times neg more or less
-1 x -1 = 1
Answer:
A is true.
Step-by-step explanation:
<h3>A is true because y=15x+75 means that they charge $15 for every person but $75 right away. For planner 2, they charge $20 a person because comparing coordinates 1 and 2, every 5 people charge $100. So to find the amount per person for planner 2, divide 100 by 5 and you'll get 20, and since 20 is 5 more than 15. A is true.</h3>
If I'm not mistaken your answer is C. 40
Answer:
The function is increasing for all real values of x where
x < –4.
Step-by-step explanation:
we have
This is a vertical parabola open downward (the leading coefficient is negative)
The vertex (h,k) represent a maximum
The roots of the function (or x-intercepts) are x=-6 and x=-2
The x-coordinate of the vertex is the midpoint of the roots
so
The y-coordinate of the vertex is
substitute the x-coordinate of the vertex in the quadratic equation
The vertex is the point (-4,4)
The function is increasing in the interval (-∞,-4)
The function is decreasing in the interval (-4,∞)
