Answer:
I can't see the options but the answer is -1,024
Step-by-step explanation:
-4^5= -4 × (-4) × (-4) × (-4) × (-4)= -1,024
The slope is (difference in 'y') divided by (difference in 'x') .
Difference in 'y' = (9 - 4) = 5
Difference in 'x' = (4 - [-1]) = 5
Slope = 5/5 = 1 .
(I don't think we need the pictures at all.)
Answer:
Slope: -1/4; Y-Intercept: 1.5
Step-by-step explanation:
Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.
Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 <em>(note: the y-intercept can also be found when x=0, for example (0,9).</em>
Hope this helped, good luck!
a. The interest earned will be $36.
b. The account balance will be $336.
Step-by-step Explanation:
Step 1:
The initial amount put into the account was $300.
This account has an interest rate of 4% every year. So we must calculate how much 4% of $300 is.
4% of $300 = 
Step 2:
So for every year, the interest of $12 is added into the account. To calculate total interest we multiply this interest amount and the number of years.
So after 3 years 
So account balance after 3 years 
.
So the interest earned is $36 and the account balance is $336 after three years.
