Which equation below is perpendicular to the line y = - 2?
Your answer:
X=-2y+4
Y=-6
X=4
o y - 4 =0(x-2)
Answer:

Fred is 4 times as old as Nathan and is also 27 years older than Nathan. Let f be Fred's age and let n be Nathan's age.
Answer:
The system of equations is
and
Fred's age is 36 years old and Nathan's age is 9 years old
Step-by-step explanation:
Let
f -----> Fred's age
n ----> Nathan's age
we know that
-----> equation A
----> equation B
equate the equations and solve for n
Find the value of f
therefore
Fred's age is 36 years old and Nathan's age is 9 years old

How many candy bars must be sold to make a profit of $700?
Answer:800
Step-by-step explanation:
I'm assuming (P) represents profit
Apply out 700 in the equation
700=1.50n-500
Add 500 to each side
1200=1.50n
Divide each side by 1.50
800=n.
800 bars must be sold
800 candy bars must be sold to make a profit of $700.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, p = 1.50n - 500, assuming no. of candy bars to be n and we had a profit of $700.
∴ No. of candy bars sold to make a profit of $700 is,
700 = 1.50n - 500.
700 + 500 = 1.50n.
1.50n = 1200.
n = 1200/1.50.
n = 800 candy bars.

c. Sophia's friend has saved $118 but is not sure how many songs she can afford if she buys the
membership and some songs. Use the expression in part (b) to write an equation that can be used to
determine how many songs Sophia's friend can buy.
okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total
The half-life of a certain radioactive substance is 45 days. There are 6.2 grams present initially. On what day
will there be less than 1 gram remaining? Day
Answer:
There will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days
Step-by-step explanation:
The given parameters are;
The half life of the radioactive substance = 45 days
The mass of the substance initially present = 6.2 grams
The expression for evaluating the half life is given as follows;
[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]
Where;
N(t) = The amount of the substance left after a given time period = 1 gram
N₀ = The initial amount of the radioactive substance = 6.2 grams
[tex]t_{1/2}[/tex] = The half life of the radioactive substance = 45 days
Substituting the values gives;
[tex]1 = 6.2 \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]
[tex]\dfrac{1}{6.2} = \left (\dfrac{1}{2} \right )^{\dfrac{t}{45}[/tex]
[tex]ln\left (\dfrac{1}{6.2} \right ) = {\dfrac{t}{45} \times ln \left (\dfrac{1}{2} \right )[/tex]
[tex]t = 45 \times \dfrac{ln\left (\dfrac{1}{6.2} \right ) }{ln \left (\dfrac{1}{2} \right )} \approx 118.45 \ days[/tex]
The time that it takes for the mass of the radioactive substance to remain 1 g ≈ 118.45 days
Therefore, there will be less than 1 gram of the radioactive substance remaining by the elapsing of 118 days.
A student solved log4(2x – 12) = 3, as shown.
Answer:
x = -6
Step-by-step explanation:
you want to solve the aswer so you wanna solve for whats in the parenthesis so your new equation should look like this:
8x + 48 = 3
you want to subtract 48 from both sides your new equation should look like this:
8x = -45
now you want to get x by itself and your new equation should be:
x = -6

Car A costs $25.95 to rent and $0.35/km to drive. Car B costs $19.95 to rent and $0.55/km to drive. Let y represent the total cost to rent a car and m represent the number of kilometers a person drives. If you are solving the equation, how many km would you have to drive for the total cost to be the same?
0.35m + 25.95= 0.55m + 19.95
1) 60 kilometers for them to be the same
2) 6 kilometers for them to be the same
3) 12 kilometers for them to be the same
4) 30 kilometers for them to be the same

Triangle ABC measures are as follows; Angle A measures 30 degrees, angle B measures (3x-9) degrees and angle C measures 29 degrees. What is the value of x?
Answer:
x = 43 1/3 degrees
Step-by-step explanation:
sum of interior angles in a triangle = 180 degrees
30 + (3x - 9) + 29 = 180
30 + 29 + (3x - 9) = 180
59 + (3x - 9) = 180
(3x - 9) = 180 - 59
(3x - 9) = 121
3x = 121 + 9
3x = 130
x = 43 1/3
