Answer:
- (x - 4)(x - 11)
Step-by-step explanation:
Given
- x² + 15x - 44 ← factor out - 1 from each term
= - 1 (x² - 15x + 44) ← factor the quadratic
Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)
The factors are - 4 and - 11 , since
- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus
x² - 15x + 44 = (x - 4)(x - 11) and
- x² + 15x - 44 = - (x - 4)(x - 11)

Answer:
[tex]b = 8[/tex]
Step-by-step explanation:
First, cross multiply across the equal sign. Note that what you do to one side, you do to the other:
[tex](b+10)(2b-7)(\frac{8}{b+10}) = (\frac{4}{2b -7})(b+10)(2b-7)\\ \\(2b -7)(8) = (4)(b+10)[/tex]
Next, distribute 8 and 4 to their corresponding parenthesis:
[tex]8(2b -7) = 16b - 56\\4(b + 10) = 4b + 40[/tex]
[tex]16b - 56 = 4b + 40[/tex]
Next, isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 56 and subtract 4b from both sides:
[tex]16b (-4b) - 56 (+56) = 4b (-4b) + 40 (+56)\\16b - 4b = 40 + 56\\12b = 96[/tex]
Isolate the variable, b. Divide 12 from both sides:
[tex]12b = 96\\\frac{12b}{12} = \frac{96}{12} \\b = \frac{96}{12} \\b = 8[/tex]
[tex]b = 8[/tex] is your answer.

Write each of the following numbers as a power with a rational exponent:
2[tex]2\sqrt32[/tex]
Answer:
2^(7/2)
Step-by-step explanation:
Here, we want to write 2√32 as a power with a rational exponent.
That would be 2 * √32
= 2 * 32^1/2
= 2 * 2^5(1/2)
= 2 * 2^5/2
According to law of indices, this becomes the following;
2^(1 + 5/2)
= 2^(7/2)

Step-by-step explanation:
2x -10 = 3x +6 -4x +8
3x=24
x=8
Answer:
x = 8 (d)
Step-by-step explanation:
Expand
2x - 10 = 3x + 6 - 4x + 8
Collect like terms
2x - 3x + 4x = 6 + 8 + 10
3x = 24
Divide both sides by 3 to make x on its own
x = 8
What is the equation of the line that passes through the point (6,6) and has a slope of 5/3
Answer:
The answer is
[tex] \huge y = \frac{5}{3} x - 4[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)\\[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (6,6) and slope 5/3
We have
[tex]y - 6 = \frac{5}{3} (x - 6) \\ y - 6 = \frac{5}{3} x - 10 \\ y = \frac{5}{3} x - 10 + 6 \\ [/tex]
We have the final answer as
[tex]y = \frac{5}{3} x - 4 \\ [/tex]

Below, you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year. (Let t = 12 represent 2012.) 2012 Value Rate $48,000 $2200 decrease per year
Answer:
[tex]y = 48000 - 2200x[/tex] --- equation
[tex]y = 37000[/tex] --- value at 5th year
Step-by-step explanation:
Given
[tex]Value = \$48000[/tex]
[tex]Rate = \$2200[/tex] decrease
Required
Determine the linear equation
Determine the value at the 5th year
Represent years with x.
If the rate in 1 year is 2200,
in x years, it'll be 2200x (decrement)
So, the value (y) at x years is.
[tex]y = 48000 - 2200x[/tex]
The value at the 5th year is when x = 5.
So, we have:
[tex]y = 48000 - 2200 * 5[/tex]
[tex]y = 48000 - 11000[/tex]
[tex]y = 37000[/tex]

Do the graphs of all rational functions have at least one asymptote or hole? Explain why or why not
A. No, a function may have neither asymptotes nor holes.
B. Yes, the function will have both a vertical asymptote and hole for any values that cause the denominator to be equal to zero.
C. Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
D. Yes, the function will have either a horizontal asymptote or hole for any values that cause the denominator to be equal to zero.
Answer:
C. Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
Step-by-step explanation:
We want to see if all rational functions always have at least one asymptote or hole.
The answer is C:
" Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero"
A rational function is something like:
[tex]f(x) = \frac{q(x)}{p(x)}[/tex]
Where q(x) and p(x) are polynomials.
The asymptotes or holes happen when the denominator is equal to zero and the numerator don't.
Now, in the cases where the numerator and denominator become zero for the same value of x, it means that we can factorize the polynomials and remove the common factor. So there we do not have a hole nor asymptote.
Now, because the denominator becomes equal to zero, this means that we are dividing by a reallly small value, then the quotient will tend to infinity or negative infinity, this means that we will have a vertical asymptote.
Then the correct option is C:
Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero

-t^2 + 12t = 32
Answer:
t = 8, t = 4
Step-by-step explanation:
-t² + 12t = 32
-t² + 12t - 32 = 0 (Subtracted 32 on both sides.)
t² - 12t + 32 = 0 (Divided by -1 on both sides.)
(t - 8)(t - 4) = 0 (Factor.)
t - 8 = 0 t - 4 = 0
t = 8 t = 4

Answer:
The pack of 12 pencils for 298 is better as it has a lower unit price.
Step-by-step explanation:
To be able to find the answer, you have to calculate the unit price for each brand by dividing the price of the pack by the number of pencils in the pack.
-298/12=24.83
-499/18=27.72
According to this, the answer is that the pack of 12 pencils for 298 is better as it has a lower unit price.

A restaurant owner was experimenting with the taste of her homestyle lemon
drink. She started with 60 litres of water. She removed 15 litres of the water and
replaced it with 15 litres of pure lemon juice.
After thoroughly stirring the new mixture, she discovered that it was too
“lemony”. So she removed 10 litres of the new mixture and replaced it with 10
litres of water. She thoroughly stirred the mixture and concluded that the new
mixture was just right.
Determine the ratio of pure lemon juice to water in the final 60 litre mixture.
Answer:
Lemon juice / water = 12,5 / 47,5 or 26,31 %
Step-by-step explanation:
First step:
We got 60 liters. of water and we replace 15 liters. of water and add 15 liters of lemon juice, then our mixture is:
60 lts. of mixture ⇒ with 45 lts. is water and 15 lts. is lemon juice
The proportion of the mixture
each liter of the mixture is 0,75 lts. of water and 0,25 of lemon juice
2 step
Removing 10 lts. of mixture implies
10 lts of mixture means 7,5 lts. of water and 2,5 lts. of lemon juice
then we have
50 lts. of mixture with (45 - 7,5 = 37,5 lts.) of water and (15 - 2,5 = 12,5 ) lts. of lemon juice
third step
Addind 10 lts. of water:
60 lts. of mixture with ( 37,5 + 10 = 47,5) lts. of water and 12,5 lts. of lemon juice
Final mixture is
60 lts. of mixture with 47,5 lts. of water and 12,5 lts. of lemon juice
Proportion
Lemon juice / water = 12,5 / 47,5 or 26,32 %
