Given the function f, evaluate f(-3), f(-2), f(-1), and f(0)
After evaluating for the function f, the value of f(-3) = -12, f(-2) = -2, f(-1) = 4, f(0) = −10
What is a function?A function is a specific type of relationship that maps inputs to precisely one output. Consider a function as a machine for useful insight. The domain of the function, which describes the types of input that the machine will accept, states that it will produce one and only one output for each input.
A function's fundamental notation is of the form f( x), where x is the input variable and f is the function's name. "F of X" should be read as this. Any time you see this notation, f(x) generally refers to a function's output, though these letters are subject to change.
We have given the function f, to evaluate f(-3), f(-2), f(-1), and f(0)
[tex]f(x)= \begin{cases}-2 x^2+6 & \text { if } x \leq-1 \\ 7 x-10 & \text { if } x > -1\end{cases}[/tex]
f(-3) = -2x² + 6 (as x < -1)
⇒ -2(-3)² + 6
⇒ -12
f(-2) = -2x² + 6 (as x < -1)
⇒ -2(-2)² + 6
⇒ -2
f(-1) = -2x² + 6 (as x < -1)
⇒ -2(-1)² + 6
⇒ 4
f(0) = 7x - 10 (as x > -1)
⇒ 7(0) - 10
⇒ −10

Using proportions, it is found that the percent of decrease in Darnel's daily water consumption was of 0%.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.
One example of application of proportions is for percentage problems, and for the case in this problem, the percent decrease is given by the change divided by the initial amount and multiplied by 100%.
For this problem, we have that:
Each day, he drank 20 ounces of water.The change was of of 0 ounces, as 20 - 20 = 0.Hence the percent decrease is found applying the following proportion:

2. two brands of canned dog food are on sale. assume that the cans are the same size. brand a costs $13.60 for eight cans and brand b costs $8.75 for fi ve cans. explain how to fi nd the unit price for brands a and b. explain how unit prices help you compare the cost of dog food.
Answer:
Brand a price is less than Brand b.
Step-by-step explanation:
given-
two brands of canned dog food are on sale. assume that the cans are the same size. brand a costs $13.60 for eight cans and brand b costs $8.75 for five cans
first-brand a costs $13.60 for eight cans
second- brand b costs $8.75 for five cans
solve first
for 8 cans-->$13.60
then,1 can -->$13.60/8
=>$1.7
in similar manner we solve for second
for 5 cans-->$8.75
then,1 can -->$8.75/5
=>$1.75
Brand a price is less than Brand b.
Unit pricing helps consumers compare the prices of packaged goods when those goods aren't sold in equal quantities. It's unit pricing that allows, for example, a shopper to tell at a glance which is the better buy: a 20-pound bag of dog food that sells for $13.95 or a 15-pound bag that sells for $10.69.

If y varies directly as x, and y=10 when x=20, find y when x=3
Answer:
y = -7
Step-by-step explanation:
If y = 10 when x = 20, then we can find the difference when we do y + 1 = x + 1, which is 11 = 21. Therefore, the difference between x and y is 10. So, we need to do 3-10, which gives us -7.

Step-by-step explanation:
Debnil has 6 teaspoons of salt. The ratio of teaspoons to tablespoons is 3 : 1.
How many tablespoons of salt does Debnil have?
The number of tablespoons Debnil has is 2 tablespoons
Number of teaspoons of salt with Debnil = 6
Ratio = 3:1
Ratio: mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another. Two quantities are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent."
Let x represent the total number of teaspoons and the tablespoons
Therefore,
6 = 3/4x
x = (6*4)/3
x = 8
So, there are a total of 8 spoons
Now, the number of tablespoons is 1/4 of the total
Hence, the number of tablespoons will be 2

which of the three curves drawn matches the graph of y= 2x^2 +x
The curve that matches the graph of:

Is the orange curve.
Which of the 3 curves matches the graph of the given function?Here we want to see which one of the graphed curves matches the graph of the quadratic equation:
y = 2x^2 + x
To check that, we can evaluate this curve in some values of x and find some points.
For example, if x = 0 then:
y = 2*0^2 + 0 = 0
So we have the point (0, 0).
Now, if x = 1 then:
y = 2*1^2 + 1 = 2 + 1 = 3
So we have the point (1,3).
So now we just need to see which of the curves passes through the points (0, 0) and (1, 3), and that one will be the orange curve.

3x-4+3x-8 linear pairs of angles.
Answer:
Step-by-step explanation:
- 36
Find the angles of this shape
Answer:
x = 100° , y = 75° , z = 135°
Step-by-step explanation:
x and 80° are a linear pair and sum to 180° , that is
x + 80° = 180° ( subtract 80° from both sides )
x = 100°
y and 105° are a linear pair and sum to 180° , then
y + 105° = 180° ( subtract 105° from both sides )
y = 75°
the sum of the interior angles of a polygon is
sum = 180° ( n - 2 ) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540°
z + x + 90° + 110° + 105° = 540°
z + 100° + 90° + 110° + 105° = 540°
z + 405° = 540° ( subtract 405° from both sides )
z = 135°
a company with 200 employees grew in size by 25% between 2005 and 2010. the company grew again by 10% between 2010 and 2015. what was the total number of employees in 2015?
The total number of employees in the company in the year 2015 is 275 employees
Number of employees in the company before increase = 200 employees
Percentage increase in employees between 2005 and 2010 = 25%
Percentage: A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test.
So, the number of employees after the increase = 200+25%of 200
= 200+50 = 250
Percentage increase in employees between 2010 and 2015 = 10%
Number of employees after increase = 250 + 10% of 250
= 250 + 25 = 275 employees
