Step-by-step explanation:
x² + 29x - 30
Product = -30
Sum = 29
Factor = 30 * (-1)
x² + 30x - 1x - 30 = x*(x + 30) -1*(x +30)
= (x + 30) (x - 1)
Answer:
(x - 30)(x - 1)

Answer:
Your answer is correct. (x-4)^2 = 3
Step-by-step explanation:
x^2 - 8x + 13 (is not a perfect square so you need to move the 13 to the right by subtraction)
x^2 - 8x + ____ = -13 (In order to get A, divide the second coefficient by 2. That would be -4 in this case. Now we need to square A to find the constant. That would be 16)
(x^2 - 8x + 16) = -13 + 16 (Whatever we do on the left we add on the right, -13+16 = 3)
(x-4)^2 = 3

Your sister helped you get a dream job at a designer clothing store and one of the perks of the job is that you get 15% off all clothing that you buy at their store. During your first month of employment you purchased $235 tax-free (before the discount) worth of clothing from the designer store. You worked 25 hours during that month at $9.50 an hour and they deducted 15% of your total paycheck for deductions. Did you still make money in your first month of employment regardless of how much you spent at their store for designer clothes? How much? Show your work.
Answer:
$197.30 revenue.
Step-by-step explanation:
As long as we realise that 15% = $237.50 total revenue - 15% of that revenue $40.20 and the other 15% was totaled prior and kept to one side as seen as expenditure.
revenue = r clothing purchase = p
r = (25 x 10 -12.50) - (p15% of e235)
r = (250 - 12.50) -( e235- p23.5 +11.73)
r = (237.50) - (expenditure 235- p35.73)
r = 237.50 -(expenditure 199.27)
r= 237.50
e = 199.27
p = 35.73
Answer with out including expenditure your sister revenue was $237.50
The 15% deduction cannot be confused with the deduction from clothes.
If we were to calculate 15% of $237.50 this would be 23.7+ 16.85 =$40.2
A different Salary related 15% contribution payments = $40.20
If these were taken from $237.50
Then $237.50- $40.20 = $197.30 revenue, but we do not have to show expenditure in the total only the workings, which is still owed being $199.27- $40.20 already paid towards.
Extension = This means because $40.20 was deducted then expenditure still to be deducted outside of the question would be e. $199.27 - $40.20 = 159.07 still owed. Saying that the 15% was to pay your sisters contribution to the clothes and not to the state.

Work out the percentage change when a price of £20 is increased to £50.
Answer:
The percentage change from 20 to 50 is 150 %
Step-by-step explanation:
(50 - 20) / 20) * 100 = 150 %
Answer:
150%
Step-by-step explanation:
Let's say the 20 increased by x%. Then, we can write the equation:
20 + x% * 20 = 50
Notice that both terms on the left side have 20, so we can factor this out:
20 * (1 + x%) = 50
Divide both sides by 20:
1 + x% = 50/20 = 2.5
Subtract 1 from both sides:
x% = 1.5
Remember that % simply means "out of 100", so x% = x/100:
x/100 = 1.5
Multiply both sides by 100:
x = 150
Thus, the percent increase is 150%.

Steve completed 9 homework problems in class. The function p(m) relates the time (in minutes) Steve spent on his homework at home to the total number of problems he completed. The input is the number of minutes worked. The output is the number of problems completed.
p(m) = m/6 + 9
Which equation represents the inverse function m(p), which uses problems completed as the input and gives minutes worked as the output?
A. m(p) = 54p + 6
B. m(p) = 6p + 54
C. m(p) = 54p - 6
D. m(p) = 6p - 54
Answer:
D. m(p) = 6p - 54
Step-by-step explanation:
substitute p(m) for y and p for x
then switch x and y
y=x/6 + 9
then switch
x=y/6 + 9
then solve to get the answer
which is y=6x-54
or m(p) = 6p - 54

If you have to check whether a number is a solution of a given equation, just plug that number in the equation and see if you get something true or false.
For example, the first option claims that -2 and 6 are solutions to the equation.
Let's check it! If we substitute [tex]x=-2[/tex] in the equation we get
[tex]3(-2)^2-34(-2)-24 = 12+68-24=56 \neq 0[/tex]
So, -2 isn't a solution to this equation. Let's check 6:
[tex]3(6)^2-34(6)-24 = 108-204-24=-120 \neq 0[/tex]
So, 6 isn't a solution either.
Keep going like this and you'll find the correct set of solutions.
Answer:
{ - [tex]\frac{2}{3}[/tex], 12 }
Step-by-step explanation:
We can solve the equation by factoring it
3x² - 34x - 24 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 24 = - 72 and sum = - 34
The factors are - 36 and + 2
Use these factors to split the x- term
3x² - 36x + 2x - 24 = 0 ( factor the first/second and third/fourth terms )
3x(x - 12) + 2(x - 12) = 0 ← factor out (x - 12) from each term
(x - 12)(3x + 2) = 0
Equate each factor to zero and solve for x
x - 12 = 0 ⇒ x = 12
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]
Thus the solution set is { - [tex]\frac{2}{3}[/tex], 12 }

The Statements have been categorized and explanation given.
Step-by-step explanation:
The following statements are true
[tex]5a\²b - 6ab^3c + 3a^5[/tex] is a fifth degree polynomial.
The degree of a polynomial is the highest power in the polynomial, therefore, [tex]5a\²b - 6ab^3c + 3a^5[/tex] is a fifth degree polynomial.[tex]5a\²b - 6ab^3c + 3a^5[/tex] contains three terms.
This is true. The terms are: [tex]5a\²b, - 6ab^3c, 3a^5[/tex][tex]12x -10x^5 - 7 + 3x^4[/tex] is equivalent to [tex]-10x^5 + 3x^4 + 12x -7[/tex]
The second polynomial is a basic rearrangement of the first polynomial, therefore the statement is true.[tex]12x - 10x^5 - 7 + 3x^4[/tex] has a leading term of [tex]-10x^5.[/tex]
The leading term is the term containing the highest power. The highest power is 5 and the term containing it is [tex]-10x^5.[/tex]FALSE
[tex]2b-6ab^3c + 3a^5[/tex] has a leading term of 5.
The leading term of this polynomial is [tex]3a^5[/tex]
Please help. 3. What is the approximate perimeter of △ABC?
15 units is wrong btw, I already tried that.
The perimeter of a triangle is the sum of the lengths of all the sides of a triangle. The perimeter of the given triangle ABC is 14.2 units.
Distance between two points x and y can be calculated using the formula : √(x²+y²)
∴ Length of AB =[tex]\sqrt{(3-(-1))^{2}+(4-1)^{2} }[/tex]= [tex]\sqrt{4^{2} +3^{2} }[/tex] = 5
Length of BC = [tex]\sqrt{((-1)-(-2))^{2}+(1-5)^{2} }[/tex] = [tex]\sqrt{1^{2}+(-4)^2 }[/tex] = √17
Length of AC = [tex]\sqrt{(3-(-2))^{2}+(4-5)^{2} }[/tex] = [tex]\sqrt{5^{2}+(-1)^2 }[/tex] = √26
Perimeter of triangle ABC = Length of AB +Length of BC + Length of AC
= 5 + √17 +√26
= 5 + 4.123 + 5.099
= 14.222
≅ 14.2
Therefore, the approximate perimeter of ΔABC is 14.2 units.

For each inequality, write all one-digit integers that satisfy it.
k>0
Final answer:
To find all one-digit integers satisfying the inequality k > 0, we list every positive one-digit integer from 1 to 9, as these are the numbers that are greater than zero and meet the conditions of the inequality.
Explanation:
The question asks to identify all one-digit integers that satisfy the inequality k > 0. This inequality means that k must be greater than 0. Since we are only considering one-digit integers, we need to list all the numbers from 1 to 9, as these are the positive one-digit integers.
1
2
3
4
5
6
7
8
9
Each of these numbers is greater than 0 and thus satisfies the inequality k > 0. Numbers that are zero or negative do not meet the requirement of the inequality.
