Answer:
a) 9a(x - 3b) - 4(x - 3b) = (9a - 4)(x - 3b)
b) 5a(2b - 3) - 4(2b - 3) = (5a - 4)(2b - 3)
c) x(2h - k) + 3y(k - 2h)
= x(2h - k) - 3y(2h - k)
= (x - 3y)(2h - k)
Step-by-step explanation:
Answer:
a) (9a-4)(x-3b)
b) (5a-4)(2b-3)
c) (x-3y)(2h-k)
Step-by-step explanation:
9a(x – 3b ) - 4 (x – 3b) = (9a-4)(x-3b)
Since both 9a and -4 are multiplied by (x-3b), they can be put in a bracket too.
5a(2b – 3 ) - 4 (2b – 3) = (5a-4)(2b-3)
Since both 5a and -4 are multiplied by (2b-3), they can be put in a bracket too.
x( 2h-k )+ 3y ( k – 2h ) = x(2h-k) - 3y (-k + 2h)
We can multiply + 3y ( k – 2h ) by (-1) to switch up the arithmetic operations.
x(2h-k) - 3y (-k + 2h) = x(2h-k) -3y(2h-k)
Since both x and -3y are multiplied by (2h-k), they can be put in a bracket too.
x(2h-k) -3y(2h-k) = (x-3y)(2h-k)

A 9 feet tall dragon ice sculpture is melting at a rate of 1.75 feet per hour. Write a linear function that represents this scenario.
Answer:
[tex]y = 9 - 1.75x[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Height = 9ft[/tex]
[tex]Rate = 1.75ft[/tex] per hour
Required:
Determine the linear function
Let y represent the function and x represent the number of hours
The function can be represented with:
[tex]y = Initial\ Height- Rate * x[/tex]
We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.
So, we have:
[tex]y = 9 - 1.75 * x[/tex]
[tex]y = 9 - 1.75x[/tex]

2 The point C ( − 3 , − 1 ) C(−3, −1) is rotated 18 0 ∘ 180 ∘ clockwise about the origin. What are the coordinates of the resulting point, C ′ C ′ ? A (3, 1)(3, 1) B (−3, 1)(−3, 1) C (3, −1)(3, −1) D (−1, −3)(−1, −3)
Answer:
A (3, 1)Step-by-step explanation:
If we have the coordinate (x,y), if this coordinate is rotated by 180 degrees clockwise, the resulting coordinate will be expressed as (-x, -y) i.e the original coordinate axis are both negated.
Given the coordinate C(-3, -1), if this coordinate is rotated clockwise about the origin, the coordinate of the resulting point will be at C' (-(-3), -(-1))
C' (-(-3), -(-1))
C' = (3, 1)
Hence option A is correct

After a 25% discount, the price of a t-shirt was $12. What was the price before the discount?
Answer:
0.75
Step-by-step explanation:
0.75 x 16 = 12
Many of you guys think it's 16 and you are some way correct but you guys forget to multiply it by 0.75
PLZ give me good reviews :)
The price before the discount was $16.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, the price of the -shirt is $12 after a 25% discount.
Since a 25% discount was given, only 75% of the actual amount was paid.
Therefore, it follows;
75% = $12
1% = $ (12/75)
100% = $(12/75) × 100
100% = $16
Hence, the price before the discount was $16.

find all real values of $t$ that satisfy the equation $t^2 = 324$. the answer is 18.
Answer:
the real values that satisfy the equation are:
[tex]t=18,\:t=-18[/tex]
Step-by-step explanation:
Given the equation
$t² = 324$
Let us solve the equation

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
[tex]t=\sqrt{324},\:t=-\sqrt{324}[/tex]
as

Last year, Amy opened an investment account with $6800. At the end of the year, the amount in the account had increased by 23.5%. How much is this increase in dollars? How much money was in her account at the end of last year?
Answer:
-The increase in dollars is $1598
-The amount in her account at the end of last year was $8398.
Step-by-step explanation:
To find the increase, you have to multiply the initial amount for the percentage increase:
6800*23.5%=1598
Now, to find the amount in her account at the end of last year, you have to add the initial amount plus the increase in dollars:
6800+1598=8398
According to this, the amount in her account at the end of last year was $8398.

Answer:
Butthead has $2.3345564757548586e+217 more money than Little Jimmy. Step-by-step explanation:
Since we need to find the difference, subtract the larger number by the smaller number. In this case, Butthead’s money minus Little Jimmy’s money. The two SUPER BIG numbers can be converted to:
2.3345564757548586e + 217 − 3.8472920439976386e + 74
This equals: 2.3345564757548586e+217
