Betty's grade in science class is affected by the number of missing assignments. The table below shows the science grade percent

Angelina_Jolie [31]

Hi!

$y=-5x+95$

<em>Plug in </em> $15$ for $x$

$y=-5(15)+95$

<em>Multiply </em> $-5$ <em>and </em> $15$

$y=-75+95$

<em>Add </em> $-75$ <em>and </em> $95$

$y =15$

-------------------------------------------------------------------------------------------------------------

Betty's percentage is 15%.

The rate of change is the amount it changes for every missing assignment, therefore it would be -5.

A bank loaned out $19,500, part of it at the rate of 11% annual interest, and the rest at 7% annual interest. The total interest

Morgarella [4.7K]

The amount loaned at the interest rate of 11% is $3000.

The amount loaned at the interest rate of 7% is $16,500

<h3>What are the linear equations that represent the question?
a + b = 19500 equation 1</h3>

0.11a + 0.07b = 1485 equation 2

Where:

a = amount loaned at the interest rate of 11%

b = = amount loaned at the interest rate of 7%

<h3>How much was loaned at 11% and 7%</h3>

In order to determine how much was loaned at 7%, take the following steps:

Multiply equation 1 by 0.11:

.11a + 0.11b = 2145 equation 3

Subtract equation 2 from equation 3:

0.04b = 660

Divide both sides by 0.04:

b = 16,500

Subtract 16,500 from 19,500 :

19,500 - 16,500 = $3000

Using the graph to the right, write the ratio in simplest form. BD/AD

Romashka [77]

Answer:

$\frac{BD}{AD} = \frac{5}{7}$

Step-by-step explanation:

Coordinate of B = 1

Coordinate of D = 6

Coordinate of A = -1

BD = |1 - 6| = 5 units

AD = |-1 - 6| = |-7| = 7 units

$\frac{BD}{AD}$

Plug in the values

$\frac{BD}{AD} = \frac{5}{7}$
