So for 4, first thing you need is slope. Choose 2 points. I am choosing (8,2) and (6,3) So, then its the second y term subtracted by the first y term over(Or divided by) the second x term subtracted by the first x term.
3-2/6-8 or 1/-2 or -.5 (negative 0.5)
Now, time to find the yintercept(yint). So, choose one of the points, Im choosing (8,2), and put it into slope intercept, but leave yint as b.
(2)=-.5(8)+b
simplify
2= -4+b
subtract -4
b=6
So, your answer is y= -0.5x+6
I will right number 6 in anoher answer
Answer:
1. 10n
2. 3x^2z^2
3. 2(9n^3 - 3n^2 + 3n - 1)
4. (Put the same thing)
5. There are no common factors so it is completely factored out.
Step-by-step explanation:
For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.
For 2, same thing, you have to find the gcf for the numbers and the variables.
3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".
4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.
Answer:
Part A:
The y-intercept is 3.25. This shows the point where the line intersects with the y-axis.
Part B:
The slope was found using the points (1,5) and (5,12). 5 -1 = 4, which is the run. 12- 5 = 7, which is the rise. 7 ÷ 4 = 1.75. This is the slope.
Input b and m;
y = 1.75x + 3.25
Now, input x;
y = 1.75(13) + 3.25
y = 22.75 + 3.25
y = 26
After 13 months of practice, the team can expect to win 26 matches.
Answer:
220/260 and 221/260
Step-by-step explanation:
multiply 11/13 by 20/20 and 17/20 by 13/13
Answer:
$89,472.58
Step-by-step explanation:
P = $82100
r = 4.3% = 4.3/100 = 0.043
T = 2 years
V = P × e^rt
V = 82100 × e^(0.043 × 2)
V = 82100 × e^(0.086)
V = 82100 × 1.0898
V = 89,472.58
The interest after 2 years is $89,472.58
