For the amount he owes Lisa it would be -12, for Kelly it would be -18 and for how much David owes him +20 or just 20, since they are GIVING him the money. So, David owes the most money, since he owes $20.

Ruben bought 6 new books for his collection. This increased his collection by 12%. How many books did he have before his purchas
Norma-Jean [14]

Answer:  The required number of books that Ruben had before purchases is 50.

Step-by-step explanation:  Given that Ruben bought 6 new books for his collection that increased his collection by 12%.

We are to find the number of books that Ruben had before purchases.

Let x denotes the number of books that Ruben had before purchases.

Then, according to the given information, we have

x+6=x+12\%\times x\\\\\\\Rightarrow 6=\dfrac{12}{100}x\\\\\\\Rightarrow 6=\dfrac{3x}{25}\\\\\\\Rightarrow 3x=150\\\\\Rightarrow x=\dfrac{150}{3}\\\\\Rightarrow x=50.

Thus, the required number of books that Ruben had before purchases is 50.

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)
Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}

(5,3) (4,-3)

x_1   y_1    \\x_2  y_2\\\\

\frac{3 - (-3)}{4-5} =\frac{-6}{-1}  = 6

slope = 6

as for y-intercept use this method in the attachment

A total of $10,000 is invested in two mutual funds. The first account yields 5% and the second account yields 6%. How much was i
Aleks [24]

Answer:

$2,500 was invested in the first account while $7,500 was invested in the second account

Step-by-step explanation:

Here in this question, we want to find the amount which was invested in each of the accounts, given their individual interest rates and the total amount that was accorded as interest from the two investments

Now, since we do not know the amount invested , we shall be representing them with variables.

Let the amount invested in the first account be $x and the amount invested in the second account be $y

Since the total amount invested is $10,000, this means that the summation of both gives $10,000

Mathematically;

x + y = 10,000 ••••••(i)

now for the $x, we have an interest rate of 5%

This mathematically translates to an interest value of 5/100 * x = 5x/100

For the $y, we have an interest rate of 6% and this mathematically translates to a value of 6/100 * y= 6y/100

The addition of both interests, gives 575

Thus mathematically;

5x/100 + 6y/100 = 575

Multiplying through by 100, we have

5x + 6y = 57500 •••••••••(ii)

From 1, we can have x = 10,000-y

let’s substitute this into equation ii

5(10,000-y) + 6y = 57500

50,000-5y + 6y = 57500

50,000 + y = 57500

y = 57500-50,000

y = 7,500

Recall;

x = 10,000-y

so we have;

x = 10,000-7500 = 2,500
