Given f(x)=9x^2 find f(-3)
Answer: f(-3) = 81
Step-by-step explanation:
f(-3) = 9(-3^2)
f(-3) = 9(9)
f(-3) = 81
Answer:
f(- 3) = 81
Step-by-step explanation:
Substitute x = - 3 into f(x) , that is
f(- 3) = 9(- 3)² = 9(9) = 81
A strawberry cake recipe need w eggs for every 200g of flour. How many eggs are needed for 1000g of flour
Answer:
5w eggs
Step-by-step explanation:
200 * 5 = 1000
so if w eggs are needed for 200 g of flour
then 5 * w eggs are needed for 200 * 5 = 1000 g of flour
Answer:
5w eggs

compound inequality for x.
8x 3/4
Answer:
There are generally 3 methods to solve inequalities
Step-by-step explanation:
By algebraic method
Example 1: Solve: 2x - 7 < x - 5
2x - x < 7 - 5
x < 2
By the number-line method.
Example 2. Solve

First, solve f(x) = 0. There are 2 real roots x1 = 1, and x2 = - 3.
Replace x = 0 into f(x). We find f(0) = - 3 < 0. Therefor, the origin O is located inside the solution set.
Answer by interval: (- 3, 1)
--------------------- - 3 ++++++++ 0 ++++ 1 ----------------
3.By graphing method.
Example 2. Solve:

.
The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0.
Therefor, the solution set is the open interval (-3, 1)
graph{x^2 + 2x - 3 [-10, 10, -5, 5]}

This question seems to be incomplete. Here is the complete question :
A toy manufacturer produces a set of blocks that can be used by children to build play structures. The product packaging team is analyzing different arrangements for packaging their blocks. One idea they have is to arrange the blocks in the shape of a cube, with b blocks along one edge.
Write an expression representing the total number of blocks packaged in a cube measuring b blocks on one edge.
A cube is a 3-dimensional object that has six faces.

4 meters 85 millimeters to milimeters.
Answer:
4085
Step-by-step explanation:
4 meters = 4000 millimeters + 85
= 4085
Answer:
By changing 4 meters 85 millimetres to milimetres we get 4085 milimetres
Step-by-step explanation:
In the first step change 4m to mm
We know that 1m = 1000mm
So, 4m = 4000mm
Now add 4000mm to 85mm
= 4000mm+85mm
= 4085mm

You offered a SALARY job of $47,603, and you are expected to work 44 hours a week
What would your hourly rate be?
Answer:
$20.81
Step-by-step explanation:
There are 52 weeks in a year.
Let's say you get paid x dollars per hour. Every week, you get paid x dollars for each hour you work. If you work 44 hours, you get paid x * 44 dollars a week. We get paid x * 44 dollars each week for a year, for 52 weeks. We can represent this as (x*44) * 52 = x * 2288. This is the amount you get paid each year. Setting that to your yearly salary of $47,603, we have
$47603 = x * 2288
divide both sides by 2288 to isolate x
x ≈ $20.81
