Answer:
No
Step-by-step explanation:
If (x - 3) is a factor then x = 3 is a root and the polynomial will equal zero for x = 3 , that is
3³ - 3(3)² + 2(3) + 2
= 27 - 3(9) + 6 + 2
= 27 - 27 + 8
= 8
since the polynomial ≠ 0 for x = 3 then (x - 3) is not a factor

12 hours theater = $96.00
10 hours car wash = $85.00
total = 22hours = $181.00
A shop sells party hats and masks. On a particular morning, 10 hats and 20 masks were sold for $30. In the afternoon, 8 hats and 10 masks were sold for $18. Find the cost of each hat and each mask.
Answer:
Both the hat and mask cost $1Step-by-step explanation:
Let the cost of each hat is x and each mask is y.
According to the question, set the equations:
10x + 20y = 308x + 10y = 18Double the second equation and subtract the first one:
8x*2 + 10y*2 - 10x - 20y = 18*2 - 3016x - 10x = 36 - 306x = 6x = 1Find the value of y:
10*1 + 20y = 3020y = 30 - 1020y = 20y = 1Equations are

Answer:
26 degrees
Step-by-step explanation:
Triangle A:
So the triangle is 24 degrees and it is an isosceles triangle so the other 2 angles are equal. All the angles in a triangle add up to 180 degrees.
180-24=156 degrees
156 divided by 2 because of the 2 angles = 78 degrees
The angles in Triangle A are 78 degrees which means one corner of the Triangle X is 78 degrees as it is vertically opposite.
Triangle B:
B= 49 degrees and the triangle is isosceles as well. 49 x 2 for the other angle which would be the same is 98 degrees. We would then do
180 -98 = 82 degrees
This means the other angle in Triangle X is 82 degrees
Triangle X:
72 degrees is the top left angle and 82 degrees is the top right angle so you do 72+82= 154 degrees
180-154= 26 degrees

Carlene is selling T-shirts for a fundraiser. The T-shirts cost $20.50 each. To date, she has raised $900. Her goal is to raise more than $9,100. How many more T-shirts, x, does Carlene need to sell to reach her goal?
Answer:
the answer would be 400.
Step-by-step explanation:
9,100 - 900 = 8,200
she would need to raise 8,200 more. to know many shirts tho, we need to divide by the cost
8,200 divided by 20.50 is 400.
400 shirts.
If I'm wrong, let me know, please.
Answer:
x=400
Step-by-step explanation:
Already sold: 900/20.50=43
Needs to sell altogether:443
Needs to sell minus already sold: 443-43=400
She needs to sell 400 more shirts.
Grace takes out a loan of $9,573.00 at a 4% simple rate for 4 years. a) How much interest will be paid after 2 years? b) How much total interest will be paid for this loan?
The interest to be paid after 2 years is $765.84
The total interest to be paid after 4 years is $1531.68
What is the simple interest?Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued.
Simple interest = principal x time x interest rate
$9573 x 2 x 0,04 =$765.84
$9573 x 4 x 0,04 = $1531.68

13) A cell phone plan cost $200 to start. Then there is a $50 charge each month. What is the total cost for x months? (Hint: Write the expression needing to find the total cost)
Answer:
50x + 200
Step-by-step explanation:
50 dollars each month (for x months) is 50x, and the initial cost is 200 (flat fee) which means that the expression is 50x+200
Answer:
50x+200
Step-by-step explanation:
Our constant term is the 200, because it's the upfront charge. Our coefficient is going to be 50, because 50 dollars are being charged each month.

A piecewise function f(x) is defined by f(x) = { –X? + x + 2
x2 – 3x+2
for x>1
x>
Part A Graph the piecewise function () and determine the range (5 points)
Part B. Determine the asymptotes of f(x). Show all necessary calculations. (5 points)
Part C. Describe the end behavior of f(x). (5 points)
Answer:
A) see attached for a graph. Range: (-∞, 7]
B) asymptotes: x = 1, y = -2, y = -1
C) (x → -∞, y → -2), (x → ∞, y → -1)
Step-by-step explanation:
Part AA graphing calculator is useful for graphing the function. We note that the part for x > 1 can be simplified:
[tex]\dfrac{-x^2+x+2}{x^2-3x+2}=-\dfrac{(x-2)(x+1)}{(x-2)(x-1)}=-\dfrac{x+1}{x-1}\quad x\ne 2[/tex]
This has a vertical asymptote at x=1, and a hole at x=2.
The function for x ≤ 1 is an ordinary exponential function, shifted left 1 unit and down 2 units. Its maximum value of 3^-2 = 7 is found at x=1.
The graph is attached.
The range of the function is (-∞, 7].
__
Part BAs we mentioned in Part A, there is a vertical asymptote at x = 1. This is where the denominator (x-1) is zero.
The exponential function has a horizontal asymptote of y = -2; the rational function has a horizontal asymptote of y = (-x/x) = -1. The horizontal asymptote of the exponential would ordinarily be y=0, but this function has been translated down 2 units.
__
Part CThe end behavior is defined by the horizontal asymptotes:
for x → -∞, y → -2
for x → ∞, y → -1

The total cost of four pens and six mechanical pencils is $16.20. The cost of each pencil is 70 cents. Using an arithmetic approach, find the cost of a pen.
Answer:
300 cents or $3
Step-by-step explanation:
Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:
4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)
m=70
We can solve this using substitution (substitute 70 for m):
4p+6(70)=1620
4p+420=1620
Subtract 420 from both sides
4p=1200
Divide both sides by 4
p=300 cents or $3

What is an arrangement?An arrangement is a permutation of a set of objects in mathematics where the order of the things is important. An arrangement is specifically an orderly succession of unique elements drawn from a set.
Consider the set "A, B, C," for instance. This set can be arranged in six different ways: ABC, ACB, BAC, BCA, CAB, and CBA. The three components of the set are stated in a precise order in each of these configurations.
The number of ways that 7 students can be arranged in a line is 7! (7 factorial) which is equal to:
7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5,040
Therefore, there are 5,040 different ways that the first seven students in line can be ordered.

if ac = 8x 14 and ec =2x + 11 solve for x
Equivalent expressions are expressions that have equal values
The value of x is 25/6
How to calculate the value of xFrom the question, the values of ac and ec are equivalent
So, we have:
8x - 14 = 2x + 11
Collect like terms
8x - 2x = 14 + 11
Evaluate the like terms
6x = 25
Divide both sides by 6
x = 25/6
Hence, the value of x is 25/6
