Answer:
3x-12=y
which equals to
1/y=1/(3x-12)
Now,multiply both sides by x
x/y=x/(3x-12)
8x/2y=4x/y=4x/(3x-12)

John's bank account had $1,320 at the end of November. In December, he bought $645 worth of
groceries and spent $225 on his mom's birthday present. Luckily, he earned $350 mowing lawns and $50
for good grades. How much money does John have at the end of December?
Answer:
850 but im not sure lol
Step-by-step explanation:
645 + 225 = 870
1,320 - 870 = 450
450 + 350 = 800
800 + 50 = 850

Answer:
x = 2 and y = 1
Step-by-step explanation:
Given equations are :
2x-y=3 ...(1)
3x+y=7 ...(2)
Add equation (1) and (2) as follows :
2x-y + 3x+y = 3 + 7
2x + 3x = 10
5x = 10
x = 2
Put the value of x in equation (1)
2(2)-y=3
4-y = 3
y = 4-3
y = 1
Hence, the solution of the given equations are (2,1).

Tiffany has crayons that she is going to melt down into a block. If each crayon has a diameter of .25 inches and a height of 3 inches, how many will she have to melt down to fill her block mold that has a volume of 6 in?? Don't include the tip of the crayon. Round your answer to the nearest whole number.
Answer:
40
Step-by-step explanation:
The volume of a cylinder is = to [tex]\pi[/tex][tex]r^{2}[/tex]h, so plug in the values and you get that each crayon has a volume of about 0.15 inches. 6/0.15 = 40. :)
£560 is divided between Kate, Nima & Roshana so that Kate gets twice as much as Nima, and Nima gets three times as much as Roshana. How much does Nima get?
Answer:
£168
Step-by-step explanation:
Amount to be shared = 560
Roshana's share = x
Nima's share = 3x
Kate's share = 2 * 3x = 6x
X + 3x + 6x = 560
10x = 560
x = 560 / 10
x = 56
Nima's share = 3x
Nima's share = 3* 56 = £168

Let f(x)=e^x and g(x)=x+6. What is the domain and range of (GoF) (x)?
Answer:
Domain: Al real values
Range: All real numbers
Step-by-step explanation:
Let f(x)=e^x and g(x)=x+6. What is the domain and range of (GoF) (x)?
Given the functions'
f(x)=e^x and g(x)=x+6.
gof(x) = g(f(x))
g(f(x)) = g(e^x)
Substitute x with e^x in g(x) as shown:
g(f(x)) = e^x + 6
The domain s the input value of x for which the function exists. Accordinf to the expression, x exists on all real values. Since x exists on all real values, hence the output f(x) also exists on all real values

If A pizza shop sells pizzas that are 10 inches (in diameter) or larger. A 10-inch cheese pizza costs $8. Each additional inch costs $1.50, and each additional topping costs $0.75.
could someone answer these?
To graph the equations (sorry i dont have a camera), use the up/down line and on the 6 put a dot, then move one space to the right, and four squares down to place your next dot. This is for y = -4x+6. To graph y = 4x - 2, go back to the up/down line, to the -2 part, and put a dot. then go to the right once, and up four times to place your next dot. when the lines connect, you should be able to find your point, at (1, 2)

Question 1
Rationalise the denominator.
9
√7-2
Answer:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6[/tex]
Step-by-step explanation:
Rationalizing the Denominator
Rationalizing the denominator means to get rid of any radicals in the denominator.
We use the conjugate of the denominator to rationalize. The conjugate of a binomial is obtained by changing the sign that is between the two terms while keeping the same order of the terms. For example, the conjugate of
[tex]\sqrt{7}-2[/tex] is [tex]\sqrt{7}+2[/tex].
We need to use the algebraic identity:
[tex](a-b)(a+b)=a^2-b^2[/tex]
Let's rationalize
[tex]\displaystyle \frac{9}{\sqrt{7}-2}[/tex]
Multiply numerator and denominator by the conjugate of the denominator:
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9}{\sqrt{7}-2}\cdot\frac{\sqrt{7}+2}{\sqrt{7}+2}[/tex]
Operate in the numerator and apply the identity in the denominator
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9(\sqrt{7}+2)}{(\sqrt{7}-2)(\sqrt{7}+2)}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{(\sqrt{7})^2-2^2}[/tex]
[tex]\displaystyle \frac{9}{\sqrt{7}-2}=\frac{9\sqrt{7}+18}{7-4}=\frac{9\sqrt{7}+18}{3}[/tex]
Dividing:
[tex]\boxed{\displaystyle \frac{9}{\sqrt{7}-2}=3\sqrt{7}+6}[/tex]

Find the value of each variable in the parallelogram.
Answer:
m = 35, n = 110
Step-by-step explanation:
Opposite angles are congruent , then
2m = 70 ( divide both sides by 2 )
m = 35
Consecutive angles are supplementary, that is sum to 180° , so
70 + n = 180 ( subtract 70 from both sides )
n = 110

Toy Universe is manufacturing a new toy and deciding on a price that will result in a maximum profit. The graph below represents profit (P) generated y each price of a toy (x).
**Graph is attached below (sorry the picture is bad quality)**
Part A: If the company wants to make a maximum profit, what should the price of a new toy be?
Part B: What is the minimum price of a toy that will produce profit for the company? Explain your answer.
Part C: Estimate the value of P(10) and explain what the value means in the problem and how this may be possible.
Part D: If the company wants to make a profit of $137, for how much should the toy be sold.
Part E:Find the domain that will only result in a profit for the company and find its corresponding range of profit.
Part F: The company owner believes that selling the toy at a higher price will result in a greater profit . Explain to the owner how selling the toy at a higher price will affect the profit.
Answer:
A: $6
B: $2.01
C: $0
D: $4.50 or $7.50
E: 0 ≤ x ≥ 10
F: The more expensive you make the toy then that will mean that less people will want to buy it for its high price.
