Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.
You've gone to fruit stand to get some fresh produce. You
notice that the person in front of you gets 5 apples and 4 oranges
for 10 dollars. You get 5 apples and 5 oranges for 11 dollars.
Create a system of equations that represents this situation.
Step-by-step explanation:
Let $x be the price of an apple and $y be the price of an orange.
5x + 4y = 10
5x + 5y = 11
btw the solution is
y = 1
x = 6/5
What does "solution" mean?
What does it mean for a point to be a solution to a linear
equation?
For example, if I say, " (2,5) is a solution to the
equation y = 2x + 3," how could you check my claim?
Answer:
A solution to a linear equation means that the ordered pair is a point that lies on that line.
If someone were to say (2,5) is a solution to the equation y= 2x+3, you could check them by plugging in 2 where the variable "x" and seeing if y =5.
In this case,
y= 2(2)+3
y=7
(2,5) is not a solution.
y = (x - 2)2 + 3
Identify the vertex of the parabola
9514 1404 393
Answer:
(2, 3)
Step-by-step explanation:
Compare the given equation ...
y = (x -2)^2 +3
to the vertex form ...
y = (x -h)^2 +k
You can see that h=2 and k=3.
The vertex of the parabola is (h, k) = (2, 3).

Solve for x.
−3x + 2b > 8
Answer:
x<2/3b+-8/3
Step-by-step explanation:
Let's solve for x.
−3x+2b>8
Step 1: Add -2b to both sides.
2b−3x+−2b>8+−2b
−3x>−2b+8
Step 2: Divide both sides by -3.
-3x/-3>-2b+8/-3
x<2/3b+-8/3
Answer is : x<2/3b+-8/3

Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.
Answer:
The quantities are not proportional.
Step-by-step explanation:
The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.
The graph represents two quantities are not proportional to each other.
What is Proportional?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.
Given:
As, A relationship is proportionate if its graph is a line or ray that passes through the origin.
and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.
Here the graph also does not pass through the origin.
Hence, the graph is not proportional.

Two of the steps in the derivation of the quadratic formula are shown below.
Step 6: = b^2-4ac/4a^2= ( x+b/2a )^2
Step 7: = +✔️b^2-4ac/2a= x + b/2a
Which operation is performed in the derivation of the quadratic formula moving from Step 6 to Step 7?
subtracting b/2a from both sides of the equation squaring both sides of the equation taking the square root of both sides of the equation taking the square root of the discriminant
Answer:
taking the square root of both sides of the equation
Step-by-step explanation:
The operation which is performed in the derivation of the quadratic formula moving from Step 6 to Step 7 is taking the square root of both sides of the equation.
What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
Given two steps in deriving the quadratic formula which is used to find the roots of a quadratic equation.
The first step is,
step 6 : (b² - 4ac) / (4a)² = (x + b / 2a)²
step 7 : ± √(b² - 4ac) / 2a = x + b / 2a
We have to find which step is done in between to transform from step 6 to step 7.
It is clear that square root is taken.
When the square root is taken in step 6,
±√[(b² - 4ac) / (4a)²] = √[(x + b / 2a)²]
√(b² - 4ac) / √(4a)² = √(x + b / 2a)²
± √(b² - 4ac) / 2a = x + b / 2a
Hence the step performed is taking the square root on both sides.

4. Manuel, a son of a school janitor, does not ask for more. He has a daily
allowance of P10 a day which is 20% of his classmate's daily allowance. How much is his classmate's daily allowance?
An allowance of P10 a day is 20% of his classmate's allowance, that is, 20% of x. So
[tex]0.2x = 20[/tex]
[tex]x = \frac{20}{0.2}[/tex]
[tex]x = 100[/tex]
His classmate's daily allowance is of P100.
5. Carla, a grade six pupil , has 24 sheets of art paper for his project in Math. If 6 sheets of art paper were used by Carla, what percent of the sheets of art paper did she use?
She used 6 sheets, of the 24. So

She used 25% of the sheets of art paper.

Samuel runs around a 1-mile track in 10 minutes, and Sophia runs around the same track in
10 minutes. Assuming they continue running at their respective speeds, how many total
miles will they run in 35 minutes? Express your answer as a mixed number.
Answer:
3.5 miles
Step-by-step explanation:
Step one:
given data
Samuel runs around a 1-mile track in 10 minutes
Samuel's speed is
speed= distance/time
speed= 1/10= 0.1 miles per minute
Sophia runs around the same track in 10 minutes
Hence Sophia's speed is also = 0.1 miles per minute
Step two:
Given that the time is 35 minutes, and their speeds are 0.1 miles per minute, we can find the distance from
speed= distance/time
distance= speed*time
distance= 0.1*35
distance= 3.5 miles

Suppose that the functions r and s are defined for all real numbers x as follows.
Answer:
a) ( r+ s) (x) = 3 x + 9
b) ( r . s ) (x) = 2 x² + 13 x +20
c) ( r- s) (x) = -1 -x
Step-by-step explanation:
Step(i):-
Given that r(x) = x +4 and s(x) = 2x + 5
a) ( r+ s) (x) = r(x) + s(x)
= x +4 + 2x +5
= 3 x + 9
( r+ s) (x) = 3 x + 9
b)
( r . s ) (x) = r(x) . s(x)
= (x+4) . ( 2x +5)
= x ( 2x +5) + 4( 2x +5)
= 2 x² + 5 x + 8 x +20
= 2 x² + 13 x +20
( r . s ) (x) = 2 x² + 13 x +20
c)
( r- s) (x) = r(x) - s(x)
= (x+4 - ( 2x +5)
= x +4 - 2x -5
= -x -1
( r- s) (x) = -1 -x
