y = 4x - 6
x = 4y - 6; must solve for y in order to solve for inverse function
x + 6 = 4y
(x + 6)/4 = y
or
(x/4) + (6/4) = y
y = (x/4) + 3/2

Answer:

Step-by-step explanation:
The equation of the line is y = ( 4/3 )x + 2.
What is an equation of a line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).
The general equation of the line is
y = mx + c
The slope of the required line will be the same as the slope of the line parallel to the required line.
m = ( 4 / 3 )
The equation of the line will be written:-
y = mx + c
y = ( 4 / 3 )x + c
-6 = ( 4 / 3 ) x -6 + c
c = 2
y = ( 4/3 )x + 2
Therefore, the equation of the line is y = ( 4/3 )x + 2.

On average, a person’s heart beats about 4.2×107 times per year. There are about 7,600,000,000 people in the world. Use this data to approximate the number of heartbeats for all the people in the world per year. Expressing your answer in scientific notation in the form a×10 b , what are the values of a and b ?
A person heart beats is 4.2 x 10∧7
there are 7,600,000,000= 7.6 x 10∧9
the heartbeats for all the people here on earth= 4.2 x 10∧7 x 7.6 x 10∧9
choosing like terms
4.2 ×7.6×10∧7×10∧9
31.92x10∧(7+9)
31.92×10∧16
a=31.92
b=16
Answer:
[tex]3.192*10^1^7[/tex]
Step-by-step explanation:
To find this value, multiply the two values given:
4.2x10^7 = 4.2 x ( 10 x 10 x 10 x 10 x 10 x 10 x 10) = 42000000
42000000 x 7600000000 = 319200000000000000
Then convert 319200000000000000 into scientific notation:
319200000000000000 = 3.19200000000000000
Cut off all the zeroes and I moved the decimal 17 places to the left, so the exponent will be positive:

The sum of 2 numbers is 54. Their difference is 116. What are the numbers?
Answer:
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.
is y = 3x^2 + 2 a linear
Answer: no
Step-by-step explanation:
an example of a linear equation is x + 1. linear means a straight line. In a linear, the highest exponent on the x opponent is 1. in the equation 3x^2 + 2, the highest exponent on the x opponent is 2 which means this is a quadratic not a linear.
Tavon has a gift card for $170 that loses $4 for each 30-day period it is not used. He has another gift card for $150 that loses $3.50 for each 30-day period it is not
used
a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal
b. What will the value of each card be when they have equal value?
Answer:
37
Step-by-step explanation:
It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Let x represent the number of 30-day periods until the value of the gift cards will be equal.
Tavon has a gift card for $90 that loses $4 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
90 - 4x
He has another gift card for $ 80 that loses $3.50 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
80 - 3.5x
For the amounts left on each card to be the same, the number of periods would be
90 - 4x = 80 - 3.5x
90 - 80 = - 3.5x + 4x
10 = 0.5x
x = 10/0.5
x = 20
The value of each card when they have equal value is
90 - 4 × 20 = 90 - 80
= $10
Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10

Your checking account has a beginning balance of $68.02. You deposited $169.23 into the account. The next week you spent $31.57
for gas and $25 to go out with friends. How much do you have left in the account?
S212.25
S205.68
$237.25
$180.68
Answer:
180.68
Step-by-step explanation:
D) $180.68
At the beginning you have 68.02 plus the 169.23 deposit which makes a new total of 237.25.Then you spend 31.57 so the new equation is (237.25-31.57)
which is 205.68 then you spend another 25 for gas (205.68-25=180.68)
So your answer is $180.68

Answer: wrote it down on paper
Step-by-step explanation:
You are considering hiring a DJ for a birthday party. The price of the DJ is $35 per hour. All customers must
pay a $75 set up fee. The fixed cost is added to the total bill.
Write an equation to determine the total bill, t, for a customer. Use h to represent the number of hours the DJ works.
t = 75h + 35
t = 35 + 75
t = 35h + 75
h = 35t + 75
Answer:
The answer is C
Step-by-step explanation:
t = bill for the customer
h= number of hours Dj worked
1) t = 75h + 35
This is wrong because h represents the number of hours the Dj worked. 75 is how much the customers paid as a setup fee.
2) t = 35 + 75
This is wrong because it's asking you to use "h" and "t" to determine the total. This is just a regular equation.
3) t = 35h + 75
This is right because as it says in the problem "The price of the Dj is $35 per hour" It also says use "h" to represent the number of hours the DJ works.
The "t" is used for the customer bill and 75 represents the setup fee
4) h = 35t + 75
This is wrong because h respresents how many hours the DJ works.
"t" represents the bill for the customer. The "t" would be in the beginning of the equation and the "h" would be behind the amount the DJ got paid per hour.
