Answer:
The equation can be used to determine the amount of money S(t) that her savings account has after t years is 
Step-by-step explanation:
A student invests $500 in a savings account
Principal = $500
Rate of interest = 4% = 0.04
We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years
Formula : 
Where A is the amount after t years =S(t)
t = time
r = rate of interest in decimals =0.04
P = Principal=500
Substitute the value in the formula :
So, 
Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is
Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
The answer is c. because the domain is the first number of each set of points
If he runs 6 mph for 1.5 hours, he will run a total of 9 miles
For b) you already have two possibilities, since you have the intercepts.
<span>(20358, 0) and (0,15834) are two possible points, although not very likely. </span>
<span>Solve for y: y= (-7/9)x + 15834 </span>
<span>Any multiple of 9 will give whole number answers. </span>
<span>Let x= 9 </span>
<span>Then y= (-7/9)(9)+ 15834 </span>
<span>Y= 15827 </span>
<span>If you want more reasonable answers, let x= 9000 </span>
<span>Then y= (-7/9)(9000)+ 15834 </span>
<span>Y= 8834 </span>
