Step-by-step explanation:

y = ax + b \\ y =  - 4 \\ x = 2 \\  a =  \frac{3}{5}  \\  - 4 =  \frac{6}{5}  + b \\ b =  - 4 -  \frac{6}{5}  \\ b =  - 4 - 1.2 =  - 5.2 \\ y = 0.6 x - 5.2

tiny-mole [99]

Answer: The campers will be 40\ miles from their car after 12 hours.

Step-by-step explanation:

<h3> The missing graph is attached.</h3>

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" the y-intercept.

We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:

m=\frac{y_2-y_1}{x_2-x_1}

Choosing the points (0,4) and (2,10), we get:

m=\frac{4-10}{0-2}=3

We can susbstitute the point (0,4) and the slope into y=mx+b and solve for "b":

4=3(0)+b\\\\b=4

Then, the equation of this line is:

y=3x+4

Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:

d=3h+4

Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute h=12 into the equation and evaluate. Then we get:

d=3(12)+4\\\\d=40

Chaney deposits $1435.73 into a savings account that pays a simple annual interest rate of 1.32%. How much interest will she ear
Aneli [31]

Answer:

Interest Chaney earns after 3 years is  $56.85

Step-by-step explanation:

Given:

Amount deposited = $1435.73

Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132

To find: Interest after 3 years

We know that the formula to calculate the interest amount is

Simple interest (S.I.) = \frac{Prt}{100}

where,

P is the initial amount deposited

r is the rate of simple interest in percentage

t is the time in years for which interest is to be calculated

Substituting the known values in the formula, we get

S.I = \frac{1435.73 x 1.32 x 3}{100}

    = 56.85

Hence the interest Chaney earns after 3 years is  $56.85
