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
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.

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.

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.

work out the value of x. 3x? x?
Answer:
x = 67.5
Step-by-step explanation:
Exterior angles always add up to 360 degrees. We have a defined right angle which takes 90 off of our 360, giving us 270 degrees. If we have x as an individual angle and also as x 3 times, then x is appearing 4 times. To find x, we divide our 270 degrees by 4 to get 67.5 . We can check this using a reversive property by multiplying 67.5 by 4 and then adding 90.
360 - 90 = 270
270 / 4 = 67.5
67.5 = x

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans. She took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. Approximately how much more in interest over the life of the loan does Nellie have to pay? a. $68,510.16 b. $53,696.16 c. $32,206.32 d. $14,814.00
Using simple interest, it is found that she has to pay $24,300 more in interest.
The amount of money after t years, in simple interest, is given by:
[tex]A(t) = P(1 + kt)[/tex]
In which:
P is the principal.k is the interest rate, as a decimal.t is the time, in years.In this problem:
Loan of $45,000, thus [tex]P = 45000[/tex].6 years, thus [tex]t = 6[/tex].The amount with 15% interest is:
Here, [tex]k = 0.15[/tex]
[tex]A(6) = 45000[1 + 0.15(6)] = 85,500[/tex]
The amount with 6% interest is:
Here [tex]k = 0.06[/tex].
[tex]A(6) = 45000[1 + 0.06(6)] = 61,200[/tex]
The difference is:
85,500 - 61,200 = 24,300
She has to pay $24,300 more in interest.

The answer is D or $14,814.00
Step-by-step explanation:
This is more than simple interest, this is something to do with amortization
this is a monthly payment calculator for a car loan
[tex]A=p\cdot\frac{\left(r\left(r+1\right)^{n}\right)}{\left(\left(1+r\right)^{n}-1\right)}\\[/tex]
This isn't exactly what we are looking for since we aren't looking for monthly payments but this can still help.
So our variables are [tex]p=45,000[/tex], where p is for principle
r is the loan rate in monthly terms or divide the interest by 12 which is [tex]r=0.0125[/tex] for when 15% is interest and [tex]r=0.0005[/tex] when 6% is interest.
and n is years times 12 or monthly periods involved so [tex]n=72[/tex]
so our equation is [tex]45000\cdot\frac{\left(0.00125\left(0.00125+1\right)^{72}\right)}{\left(\left(1+0.00125\right)^{72}-1\right)}[/tex]
which is equal to 951.53
This number is our monthly payment
so for the full cost is [tex]951.53*12*6[/tex]
that equals 68510.16
now for when interest is equal to 6%
[tex]45000\cdot\frac{\left(0.0005\left(0.0005+1\right)^{72}\right)}{\left(\left(1+0.0005\right)^{72}-1\right)}[/tex]
this is equal to [tex]745.78*12*6[/tex]
so for the full cost is
so the extra interest is equal to the larger number minus the smaller one
[tex]68510.16-53696.16[/tex]
which equals
14,814.00 exactly

Answer: is this what your looking for
Step-by-step explanation:
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:
[tex]3.192*10^1^7[/tex]

Answer:
y = 3
Step-by-step explanation:
If the line needs to be parallel to the x axis, it must be Horizontal. The formula for lines like this is y= mx+c with m being the gradient. With a horizontal line, the gradient is 0 and therefore we get y=c.
To find c, we need to find the y intersect which is where the line passes through the y axis. Since it is horizontal and passes through the dot, we can find that c = 3 as the dot is at 3 on the vertical axis.
From this, we can see that the equation is y = 3.
Answer:
3
Step-by-step explanation:
the x-axis is horizontal and the numbers above and below it are 4 and 2 and the dot was right on the line so it was 3
