Match the following rational expressions to their rewritten forms.
Rational Expressions:
x^2+x+4/x-2
x^2-x+4/x-2
x^2-4x+10/x-2
x^2-5x+16/x-2
Rewritten Forms:
(x-2)+6/x-2
(x+3)+10/x-2
(x+1)+6/x-2
(x-3)+10/x-2
Answer:
Answer image is attached.
Step-by-step explanation:
Given rational expressions:
[tex]1.\ \dfrac{x^2+x+4}{x-2}\\2.\ \dfrac{x^2-x+4}{x-2}\\3.\ \dfrac{x^2-4x+10}{x-2}\\4.\ \dfrac{x^2-5x+16}{x-2}[/tex]
And the rewritten forms:
[tex](x-2)+\dfrac{6}{x-2}\\(x+3)+\dfrac{10}{x-2}\\(x+1)+\dfrac{6}{x-2}\\(x-3)+\dfrac{10}{x-2}[/tex]
We have to match the rewritten terms with the given expressions.
Let us consider the rewritten terms and let us solve them one by one by taking LCM.
[tex](x-2)+\dfrac{6}{x-2}\\\Rightarrow \dfrac{(x-2)^{2}+6 }{x-2}\\\Rightarrow \dfrac{x^2-4x+4+6 }{x-2}\\\Rightarrow \dfrac{x^2-4x+10}{x-2}[/tex]
So, correct option is 3.
[tex](x+3)+\dfrac{10}{x-2}\\\Rightarrow \dfrac{(x+3)(x-2)+10}{x-2}\\\Rightarrow \dfrac{(x^2+3x-2x-6)+10}{x-2}\\\Rightarrow \dfrac{x^2+x+4}{x-2}[/tex]
So, correct option is 1.
[tex](x+1)+\dfrac{6}{x-2}\\\Rightarrow \dfrac{(x+1)(x-2)+6}{x-2}\\\Rightarrow \dfrac{x^{2} +x-2x-2+6}{x-2}\\\Rightarrow \dfrac{x^{2} -x+4}{x-2}[/tex]
So, correct option is 2.
[tex](x-3)+\dfrac{10}{x-2}\\\Rightarrow \dfrac{(x-3)(x-2)+10}{x-2}\\\Rightarrow \dfrac{x^2-3x-2x+6+10}{x-2}\\\Rightarrow \dfrac{x^2-5x+16}{x-2}[/tex]
So, correct option is 4.

The total saved amount for Jorge, Janet and Rob is $55.8
Mathematical Expression
Mathematical Expressions are statements that have at least two terms that include numbers, variables, or even both, and are linked by an operator.
How to solve mathematical expression for the given condition?Jorge has saved $ 15.50
Janet's saving is [tex]\frac{1}{5}\times \$15.50[/tex]
That is, Janet has saved [tex]\$3.1[/tex]

Answer:
He can run 112 yards in 12 seconds
Step-by-step explanation:
Here, we want to know the number of yards he can run in 12 seconds
From the question, we are told that his running rate is 38 yards in 4 seconds
So the number of yards he can run in 12 seconds will be;
38 * 12/4
= 38 * 3 = 114 yards

Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10

On a test a student got 15 problems correct out of a total of 20 problems. What percent did the student get, begin emphasis, incorrect, end emphasis,?
Answer:
I think what you got is correct
The percentage of incorrect problems is 25%.
Option D is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of problems = 20
Number of correct problems = 15
The number of incorrect problems.
= 20 - 15
= 5
The percentage of incorrect problems.
= 5/20 x 100
= 25%
Thus,
25% were incorrect problems

Suppose f(x) = x2 and g(x) = 5x2. Which statement best compares the graph of g(x) with the graph of f(x)?
A.
The graph of g(x) is the graph of f(x) horizontally stretched by a factor of 5.
B.
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
C.
The graph of g(x) is the graph of f(x) vertically compressed by a factor of 5.
D.
The graph of g(x) is the graph of f(x) shifted 5 units right.
Answer:
B. The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5
Step-by-step explanation:
It is a quadratic and in the form:
f(x) = a(x-h)^2 + k
In this case a = 5, and if a is greater than 1, then the parabola is vertically stretched. It is not vertically compressed because a is not less than 1.
h and k are irrelevant because there are no horizontal or vertical shifts in the graph.
Therefore, when compared to f(x) = x^2, the graph has only been vertically stretched by a factor of 5.
Answer:
the graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

ANSWER ASAPPPP PLZZZZ MARKING BRAINLIEST HELPPP
Answer:
12.72 dollars per hour
Step-by-step explanation:
Her original money is $12 per hour. We know that 6% in a decimal is 0.06. But if we multiply 0.06 and $12, it would get an answer that is decreasing than increasing. So we can get this equation. 12+0.06*12. ( 12 dollars plus 6% of 12 dollars) If we divide by 12, we get: 12( 0.06+1). 0.06+1=1.06. And 1.06*12 is 12.72 dollars per hour now.

Rewrite each algebraic expression in an equivalent form with the fewest
number of terms possible.
a. 6(x + 7)(x + 2)
b. (2y – 5)
c. (5x + 4y)(2x - y)
d. (3x + 7)(3x – 7)
e. (t + 2) – (4t +9) – t
Answer:
Step-by-step explanation:
The terms will be multiplied in order to get the simplified polynomials.
a. 6(x + 7)(x + 2)
[tex]6(x + 7)(x + 2)\\=6[x(x+2)+7(x+2)]\\=6(x^2+2x+7x+14)\\=6(x^2+9x+14)\\=6x^2+54x+84[/tex]
The simplified form of 6(x + 7)(x + 2) is [tex]6x^2+54x+84[/tex]
b. (2y – 5)^2
Using the formula: [tex](a-b)^2 = a^2+b^2-2ab[/tex]
[tex]=(2y)^2+(5)^2-2(2y)(5)\\=4y^2+25-20y[/tex]
The simplified form is: [tex]4y^2-20y+25[/tex]
c. (5x + 4y)(2x - y)
[tex]=5x(2x-y)+4y(2x-y)\\=10x^2-5xy+8xy-4y^2\\=10x^2+3xy-4y^2[/tex]
The simplified form of (5x + 4y)(2x - y) is [tex]10x^2+3xy-4y^2[/tex]
d. (3x + 7)(3x – 7)
Using the formula: [tex](a+b)(a-b) = a^2-b^2[/tex]
[tex]= (3x)^2-(7)^2\\= 9x^2-49[/tex]
The simplified form of (3x + 7)(3x – 7) is [tex]9x^2-49[/tex]
e. (t + 2) – (4t +9) – t
[tex]=t+2-4t-9-t\\=t-4t-t+2-9\\= -4t-7[/tex]
The simplified form of (t + 2) – (4t +9) – t is [tex]-4t-7[/tex]
Hence,
a. The simplified form of 6(x + 7)(x + 2) is [tex]6x^2+54x+84[/tex]
b. The simplified form is: [tex]4y^2-20y+25[/tex]
c. The simplified form of (5x + 4y)(2x - y) is [tex]10x^2+3xy-4y^2[/tex]
d. The simplified form of (3x + 7)(3x – 7) is [tex]9x^2-49[/tex]
e. The simplified form of (t + 2) – (4t +9) – t is [tex]-4t-7[/tex]

3 / 24
Answer:
C. The bagels at Store B are $0.04 more expensive than the bagels at Store A.
Step-by-step explanation:
Find the unit rates of both stores by dividing the price by the number of bagels:
Store A:
2.05/5
= 0.41
Store B:
1.35/3
= 0.45
Store B's bagels are $0.04 more than Store A's, so C is the correct answer.
