The rate of change per year is 3 million per year.
Answer:
see below
Step-by-step explanation:
The point-slope form of the equation of a line is ...
y -k = m(x -h) . . . . . . . . line of slope m through point (h, k)
Comparing this form to the equation you are given, we can match parts to see that ...
That is, your line has a slope of -3/4 and goes through the point (-4, -2).
__
To graph this line, it is often convenient to start with the given point, then use the slope to find another point. The given point is (-4, -2).
The slope is "rise"/"run". A slope of -3/4 tells you the line will drop 3 units for each 4 units it moves to the right. If we add 4 to the x-value of the given point, we get 0. If we add -3 to the y-value of the given point, we get -5. So, another point on the line is (0, -5).
Knowing these two points, you can draw the line through them to graph the equation.
Answer:All these are equivalent, valid answers:
y < -12
all real numbers less than - 12:
( - ∞ , - 12)
{ y ∈ R | y < - 12}
Explanation:
1) Starting pointL inequality (1/2)y + 6 < 0
2) subtract 6 from both sides:
(1/2)y + 6 - 6 < 0 - 6
(1/2) y < - 6
3) multiply both sides by 2:
(2)(1/2)y < - (2) (6)
y < -12
4) That is all real numbers less than - 12:
Equivalent to ( - ∞ , - 12) or { y ∈ R | y < - 12}
That upside down u looking thing is the " intersection " of sets a and b. That means only the numbers that are in both sets.
answer is : 2,4
Answer: $48
Step by step:
1. 30 packs times 64 dollars is 1920
2. 1920 divided by 40 packs is 48
because if you pay 64 for 40 packs and your trying to figure out how much for 30 packs you will want to set it up like this:
then you will use fishy method Google fish method in math if this doesn't help
