First, you need to get delta which is b squared minus 4ac. If delta is higher than cero, the polynomial has two solutions, if it is less, the polynomial has no real solutions and if it is the same, it has one solution.
Although that is only for second grade ecuations

==============================================
Explanation:
The most money made from selling drinks is $150. Divide this over the cost per drink to get 150/(1.50) = 100; indicating that at most 100 drinks are sold per day. This is the largest that d can get because d represents the number of drinks sold.
The smallest d can get is d = 0 to mean that no drinks are sold.
In short: d is between 0 and 100, including both endpoints. We write to indicate this. This is the domain because the domain represents all the possible inputs allowed.
---------------------------------------------------
The range is the set of allowed outputs.
If we plugged in d = 0, then you would find F(d) = 0 as well. If you don't sell any drinks, then you earn $0. This is the smallest item in the range.
On the other side of things, the largest item in the range is 150 because this value was given to us. It's the upper limit or ceiling value of how much money is made from drinks. You can also find this by plugging d = 100, the largest domain value, into the function to get F(d) = 150.
Therefore the range is to indicate that F(d) is between 0 and 150 inclusive of both endpoints.
Answer:
y = √-1040/7
Step-by-step explanation:
The equation of a unit circle is expressed as;
x²+y² = 1
Given the coordinate of P = (-33/7, y)
Substitute the coordinate into the give expression and find y;
(-33/7)²+y² = 1
Expand
y² = 1-(-33/7)²
According to difference of two square
y² = (1+(-33/7))1-(-33/7))
y² = (1-33/7)(1+33/7)
y² = -26/7(40/7)
y² = -1040/49
y= √-1040/49
y = √-1040/√49
y = √-1040/7
Hence the value of y is y = √-1040/7
Y= -3x +4
So from the equation we can tell that m is 3 .
(0,-1)
(x, y)
0 = x
-1 = y
M = 3
Y = mx+ c
Just insert it
-1 = 3(0) + c
-1 = c
So thts mean the answe is y = 3x-1
I'm not going to give you the answer, but I'm going to give really obvious hints to you.
Supplementary angles are when two angles add up to 180 degrees.
Complimentary is when two angles add up to 90 degrees.
I'm not sure how you find angles m<y and m<v, I can't even see the letter m on the attachment.
There are two angles that are adjacent to <GXF, and you are free to choose which ever ones you like: <FXE and <CXG
