cups of shampoo concentrate
Answer:
8 Shampoo Concentrate
Step-by-step explanation:
There's a ratio of 9:2 so for every 9 cups of water there's two cups of shampoo concrete.
We'll need 9 multiplied by 4 is 36
so we need to multiply 2 with 4
4 multiplied by 2 is 8
Answer:
8. is the answer
Step-by-step explanation:
Answer:
g = 5
Step-by-step explanation:
Step 1: Write out equation
8g + 10 = 35 + 3g
Step 2: Subtract 3g on both sides
5g + 10 = 35
Step 3: Subtract 10 on both sides
5g = 25
Step 4: Divide both sides by 5
g = 5
If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1
So the constant c is -2 and that means the value of f(-4) is
f(-4)=-2(-4)+3=8+3=11
Thus, the value of f(-4) is 11.
About why does "c" have to be -2, here's the proof.
Given y = f(x), therefore.
y=cx+3
Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3
1 - 3 = c and therefore, -2 = c #
So this is the proof that c = -2

Answer:
20 cakes
Step-by-step explanation:
Given
28 cakes in 7 days
Required
Determine the number of cakes in 5 days
Represent the required with x. The question illustrates proportionality.
First, we need to represent the given and required as a ratio
Convert ratios to fraction
Solve for x
Answer:
(a) F(x) = 2x^2 - x - 1
Step-by-step explanation:
The quadratic regression function of a graphing calculator does this nicely.
The one attached shows the function to be ...
F(x) = 2x^2 -x -1
__
Additional comments
The supplied point (0, -1) tells you the y-intercept is -1. That means the constant in the function's equation will be -1. Only one answer choice has that.
F(x) = 2x^2 -x -1
__
As always, the first step in problem solving should be to look at the problem, and look at the available solution choices. Understanding these things will generally allow you to throw out answer choices that don't provide a sensible answer to the question. Here, that leaves you with only one answer choice, which is all you need.
