A bank loaned out $15,000, part of it at the rate of 7% per year and the rest at 17% per year. If the interest received in one year totaled $2000, how much was loaned at 7%?
How much of the $15,000 did the bank loan out at 7%?

Answers

9514 1404 393

Answer:

$5,500

Step-by-step explanation:

Let x represent the quantity loaned at 7%. Then the amount loaned at 17% is (15000-x), and the total interest is ...

0.07x +0.17(15000 -x) = 2000

-0.10x = -550 . . . . . . . . . collect terms, subtract 2550

x = -550/-0.10 = 5500 . . . . divide by the coefficient of x

The bank loaned $5,500 at 7%.

Answers

Answer:

Function that fits the points [tex](0,5),\,(2,-13)[/tex] is given by [tex]x+9y=45[/tex]

Step-by-step explanation:

Let [tex](x_1,y_1)=(0,5),\,(x_2,y_2)=(2,-13)[/tex]

Slope of a line joining points [tex](x_1,y_1),\,(x_2,y_2)[/tex] is given by [tex]m=\frac{x_2-x_1}{y_2-y_1}[/tex]

Which of the following represents a coefficient from the expression given?

5x - 21 + x2

Answers

Answer:

1 or 5

Step-by-step explanation:

A coefficient is "a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4xy)".

So, in this case, the coefficient of 5x would be 5.

The coefficient of x^2 would be 1.
