Answer:
y = -0.904, 19.904
Step-by-step explanation:
f(y) = 9
f(y) = sqrt(y + 99)
-------------------------------------------
9 = sqrt(y +99) - y
81 - 18y + y^2= y + 99
-19y + y^2 = 18
y(y - 19) = 18
y = -0.904, 19.904
(I used a calculator to solve those values)
The answer is x=-23 if the last two numbers (the 4 and the 6: 4 6) are being multiplied.
Your answer would be y< -3/2x+1
You slope is negative because the line goes from left to right and your slope is -3/2 because it rises 3 and goes to the left 2. Remember that your slope represents your rise over your run.
Your equation is also only > and not less then or equal to because it is a dotted line.
Happy studying!
Answer:
1.) 9/5 or 1.8 or 1 4/5
2.) 17/2 or .53125 or 8 1/2
Answer:
1440
Step-by-step explanation:
We can solve this problem by applying the rule of three.
In fact, we know that:
- Over a package of 210 candies,
- The number of brown candies is 63
- Here we want to find what is the number of brown candies when the total number of candies contained in the package is 4800
So we can set up the following rule of three:

where
x = number of brown candies when the total number of candies contained in the package is 4800
Solving the expression for x, we find:

So, Sarah can expect to find 1440 brown candies in a package of 4800 pieces.
