Answer:
step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)
step 2. so the question becomes is C a quadratic
step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4
step 4. write out the y values: -126, -14, 2, 18
step 5. write out the differences: 140, 16, 16
step 6. write out the differences: -124, 0.
step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't
step 8. C is not a quadratic.

Graph f (.x) = x3 – 4x3 + x2 + 2. Identify the x-intercepts and the points where the local maximums and local
minimums occur. Determine the intervals for which the function is increasing or decreasing. Round to the nearest
hundredth, if necessary.
After graphing x⁵ – 4x³ + x² + 2, we have
x-intercepts : x ≈ 2.16, x = 1, x ≈ 1.75

-1 + 14x = 12x + 17
Answer:
x = 9
Step-by-step explanation:
-1 + 14x = 12x + 17
Rearrange terms.
14x - 1 = 12x + 17
Add 1 to both sides of the equation.
14x - 1 + 1 = 12x + 17 + 1
Simplify.
14x = 12x + 17 + 1
14x = + 12x + 18
Subtract 12x from both sides of the equation.
14x - 12x = + 12x - 12x + 18
Simplify.
2x = + 12x - 12x + 18
2x = 18
18 ÷ 2 = 9
x = 9

In a shop, the cost of 4 shirts, 4 pairs of trousers and 2 hats are $560. The cost of 9 shirts, 9 pairs of trousers and 6 hats is $1,290. What is the total cost of 1 shirt, 1 pair of trousers and 1 hat?
Answer: Given:
4 shirts, 4 pairs of trousers , and 2 hats is $560
9 shirts, 9 pairs of trousers , and 6 hats is $1,290
1) Let x be the price of 1 shirt
Let y be the price of 1 pair of trousers
Let z be the price of 1 hat
2) 4x + 4y + 2z = 560
3) 9x + 9y + 6z = 1,290
4) (9x + 9y + 6z) / 3 = 1,290 / 3
3x + 3y + 2z = 430
5)
4x + 4y + 2z = 560
- (3x + 3y + 2z = 430)
x + y = 130
6) 3(x+y) + 2z = 430
3(130) + 2z = 430
390 + 2z = 430
2z = 430 - 390
2z = 40
z = 40/2
z = 20
7) x = price of 1 shirt; y = price of 1 pair of trousers ; z = price of 1hat
x + y = 130 ; z = 20
130 + 20 = 150
The price of 1 shirt, 1 pair of trousers, and 1 hat is $150.
So this is not impossible!

Nhich number line represents the solutions to |x + 4| = 2?
Answer:
I'm guess that the parentheses looking sign means absolute value so the answer should be the first choice. (-6, and -2)
Step-by-step explanation:
-6 plus 4 = -2 but since we are doing absolute value then the absolute value of -2 is 2.
-2 plus 4 = 2 So, this is also correct because the answer is 2.
Hope this helps! :)
The solution is represented by the first number line, which has the solutions x=-6 and x=-2.
What is number line?A number line is a pictorial representation of numbers on a straight line. In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers. Every point of a number line is assumed to correspond to a real number, and every real number to a point.
here, we have,
We have an absolute value function for the equation.
This means that we should have two different solution in the real number line.
As the equation is
|x + 4| = 2
when we clear out the absolute value, we will have two possible solutions:
x + 4 = 2
and
-(x + 4) = 2
now we clear x from both equations
x + 4 = 2 ⇒ x = -2
-(x + 4) = 2 ⇒ x = -6
Then, we have that x=-2 and x=-4 are the solutions for the equation, and therefore the number line that represents the solution is the first one, where the points -6 and -2 are highlighted.

for #2: 70x + 100 = y
Step-by-step explanation:
you pay $70 for x amount of time with will equal your total therefore it's 70x = y
if you have to pay a one-time fee of $100.00 then you have to add that to your equation giving you 70x + 100 = y

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.
x = ±3
x = 3
x = -3
x = ±9
2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.
h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)
Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:
[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]
And that:
[tex]h(x)=f(x)/g(x)[/tex]
And we want to now for which values of x is h(x) undefined.
So, by substitution:
[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]
Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:
[tex]x^2-9=0[/tex]
Add 9 to both sides:
[tex]x^2=9[/tex]
Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:
[tex]x=\pm 3[/tex]
So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:
[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]
And we want to find:
[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]
So:
[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]
Distribute:
[tex]h(x)=3^x-3^{2x}+3^x[/tex]
Combine like terms:
[tex]h(x)=2(3^x)-3^{2x}[/tex]
Rewrite:
[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]
Factor out:
[tex]h(x)=3^x(2-3^x)[/tex]
So, our answer is C.
Find the real solution(s) of the following equation. n to the power of 3 =64
Answer:
n = 4
Step-by-step explanation:
To do this you would find the cube root of 64 which is 4.
n =4 will be the only solution of the following equation. n to the power of 3 =64.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given an equation n to the power of 3 =64.
This equation can also be represent as:
n³ = 64
taking cube root of the Both sides
n = ∛64
n = 4
Therefore, the real solution of the following equation. n to the power of 3 =64 is n = 4.
