Answer:
$554.58
Step-by-step explanation:
The interest on the loan can be computed by first determining the future value of the loan in three years as follows:
FV=PV*(1+r)^n
PV is the amount of the loan which is $2,000
r is the interest rate which is 8.5%
n is the number of years which is 3 years
FV=$2000*(1+8.5%)^3=$ 2,554.58
Since the value of the loan in three years is $ 2,554.58 ,the interest on the loan is the difference between the future value and the present value
interest=$ 2,554.58-$2,000.00=$554.58
A quadratic equation has exactly one real number solution. Which is the value of its discriminant?

Determine whether or not the equations represent a direct variation . Sort the equations into the appropiate category.
Answer:
Direct variation: y = 3x, y = (2/7)x, and -0.5x = y
Not direct variation: x = -1, y = 2.2x + 7, and y = 4
Step-by-step explanation:
We know that the equation for direct variation is y = k · x, where you can fill in for k whatever number you want.
So, let’s figure this out by looking at the equations.
Equation 1: y = 3x
We know this is a direct variation equation because it all fits together and the 3 is a substitute for the variable, k.
Equation 2: x = -1
This is not an example of direct variation because:
1) the variable by itself on one side is x, when it is supposed to be y
2) there is only one number, -1, when instead it should say, -1x.
Equation 3: y= (2/7)x
This is an example of direct variation because the 2/7 is filling in for the k, and everything else matched the direct variation equation.
Equation 4: -0.5x = y
Since it doesn’t matter on which side y is, let’s just turn the equation around to make it simpler.
Now we have:
y = -0.5x
This makes sense because we have everything a direct variation equation needs to have plus the -0.5 substituting in for the k.
Equation 5: y = 2.2x + 7
This is also not an example of direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.
Equation 6: y = 4
This is not an example of direct variation because there is no variable x in here! We have a k, but not an x!
Hope this helps! :)
The equations represent Direct variation are y = 3x, y = (2/7)x, and -0.5x = y
The equations represent Not direct variation: x = -1, y = 2.2x + 7, and y = 4
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We know that the equation for direct variation can be written as;
y = kx,
Equation 1; y = 3x
This is a direct variation equation because the 3 is a correct value for the variable, k.
Equation 2: x = -1
This is not an example of direct variation because the variable by itself on one side is x, when it is supposed to be y at that place.
Equation 3: y= (2/7)x
This is direct variation because the 2/7 is filling in for the k.
Equation 4: -0.5x = y
Since it doesn’t matter on which side y is, then just turn the equation around to make it simpler.
Now we have;
y = -0.5x
This is a direct variation equation that needs to have plus the -0.5 substituting in for the k.
Equation 5: y = 2.2x + 7
This is also a direct variation because although it has practically everything that an equation with direct variation has to have, it has that extra 7 there that ruins the equation.
Equation 6: y = 4
This is not an example of direct variation because there is no variable x. We have a k, but not an x!

Graph y=−83x+9.
Identify the x-intercept.
Answer:
x-intercept=-74
Step-by-step explanation:
for x-intercept (y=0)
y=83x+9
0=83x+9
-83x=-0+9
-83x=9
x=9/-83
x=-0.1
Answer:
x = -27/8
Step-by-step explanation:
y = [tex]\frac{8}{3} x + 9[/tex]
to find x intercept let y = 0 then solve for x
0 = [tex]\frac{8}{3} x + 9[/tex]
-9 = [tex]\frac{8}{3} x[/tex]
divide both sides by 3
-9x3 = 8x
-27 = 8x
8x = -27
x = -27/8

Find the Mean for 15 points
Hello there!
Mean is the average of a set of numbers.
To find the mean, we have to add all the numbers and divide by how many there are.
Add: 68 + 55 + 72
Equals: 195
However, we have to find the mean of the 3 rounds in the 4th fight.
Add: 55 + 42 + 40
Equals: 137
Then, we divide it by 3.
Equals: 45.7
Next, add it to 195 since it was of 3 separate fights.
195 + 45.7 = 242.5
Lastly, divide it by 6 since there were 6 numbers in the data set.
Divide: 242.5/6
Equals: 40.42
Therefore, our mean for the 4 fights is 40.42 or 40.
There's another answer that we can get by simply adding up all the numbers and dividing it by 6.
Add: 68 + 55 + 72 + 55 + 42 + 40
Equals: 332
Then, we divide by 6.
Divide: 332/6
Equals: 55.33
So, yeah 55.33 would be the better mean then 40 since 40 makes it seem very low.

Mean x¯¯¯ 55.333333333333

It's A, 1/5^9.
Ya take the two exponents, and subtract them. Now ya have 5^-9/5.
Since we can't have a negative exponent, we put it on the bottom.
So we get the answer 1/5^9. Hope this helps!
Answer:
1/5^9
Step-by-step explanation:
5^-6 goes down and become 5^6
then 5^3 is times 5^6, when multiplying two same bases their power has to be added not multiplied. so 6 plus 3 is 9. the nine is the power.
the final answer is 1/5^9 or the first choice

What is the equation of the line that has a slope of 3 and passes through the point (1, –2)?
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute (1, - 2) into the partial equation
- 2 = 3 + c ⇒ c = - 2 - 3 = - 5
y = 3x - 5 ← equation of line

A line plot named A. Yes. There are 16 bolts that have lengths greater than 1 inch, which is just enough. B. Yes. There are 18 bolts that have lengths greater than 1 inch, which is more than enough. C. No. There are only 3 bolts with lengths greater than 1 inch, which is not enough. D. No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough
Answer:
D No. as there are only 12 bolts longer than 1inch.
Mr. Slivka needs 16 bolts of greater than 1 measure, and there are only 12.
Step-by-step explanation:
We cannot include 1 inch data as this is not over 1 inch like the 1inch 2/8 and 1inch 4/8 etc. the greater measures of over 1 inch count to 12.
We know they are greater as they do not have a negative sign next to the added fraction of 1 2/8 or 1 4/8.

The figure shows two rectangles. In order to get the two areas, we should be able to find the area of each and add them together.
The formula of the area of the rectangle = L * W
First rectangle [tex]= 25 * 8[/tex] = 200
Second rectangle = 25 * 35 = 875
Adding them together would yield 1075 sq ft.

A level differentiation question. Mainly stuck on the 4-x/x part. Help would be appreciated.
Answer:
see explanation
Step-by-step explanation:
Differentiate [tex]\frac{4-x}{x}[/tex] using the quotient rule, given
y = [tex]\frac{f(x)}{g(x)}[/tex] , then
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{g(x)f'(x)-f(x)g'(x)}{g(x)^2}[/tex]
Here f(x) = 4 - x ⇒ f'(x) = - 1
g(x) = x ⇒ g'(x) = 1 , thus
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{-x-(4-x)}{x^2}[/tex] = [tex]\frac{-x-4+x}{x^2}[/tex] = - [tex]\frac{4}{x^2}[/tex]
-----------------------------------------
Given
y = 3x² + [tex]\frac{4-x}{x}[/tex], then
[tex]\frac{dy}{dx}[/tex] = 6x - [tex]\frac{4}{x^2}[/tex] ← evaluate for x = 2
[tex]\frac{dy}{dx}[/tex] = 6(2) - [tex]\frac{4}{4}[/tex] = 12 - 1 = 11 ← as required
Let me know if you require assistance on (b) and (c)

。☆✼★ ━━━━━━━━━━━━━━ ☾
Answer:
It is x > -5
Step-by-step explanation:
Equation: -3x + 8 < 23
First, we have to move the constant to the other side. By moving it to the other side, the sign also changes becoming -3x < 23 - 8.
Now we simplify: 23 - 8 becomes 15
New equation: -3x < 15
Finally, we want the X by itself, and to do that, we must divide -3 to both sides. Keep in mind that when we multiply or divide, the sign '<' also changes.
[tex]\frac{-3x}{-3}[/tex]<[tex]\frac{15}{-3}[/tex] = x > -5

Robert has a collection of nickles, dimes, and quarters. The total value of the coins is $8.50. He has 3 times as many nickles as dimes, and 10 more quarters than dimes. How many of each coin does he have.
Answer:
As we know:
A nickle is worth 5 cents.
A dime is worth 10 cents.
A quarter is worth 25 cents.
Here is what Robert had:
Number of nickles (a)
Number of dimes (b)
Number of quarters (c)
Here is assumption:
5a + 10b + 25c = 850
a = 3b
c = b + 10
=> 5(3b) + 10b + 25(b + 10) = 850
=> 50b + 250 = 850
=> 50b = 600
=> b = 600/50 = 12
=> a = 3b = 3 x 12 = 36
=> c = b + 10 = 12 + 10 = 22
=> Number of nickles: 36
=> Number of dimes: 12
=> Number of quarters: 22
Hope this helps!
