Answer:
y = 2.5x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the gradient or slope and b is the y-intercept.
To find the gradient/slope (m), we need to do change in y ÷ change in x.
- Pick two co-ordinates on the line; (0, 5) and (-2, 0)
- Subtract the y co-ordinates; 5 - 0 = 5
- Subtract the x-co-ordinates; 0 - -2 = 2
- Finally, divide 5 by 2; 5 ÷ 2 = 5/2 or 2.5
Now we have y = 2.5x + b. The y-intercept is simply where the line crosses the y axis (it crosses at 0,5). This means the equation of the line is y = 2.5x + 5.
Hope this helps!
Answer:
recursive rule for the given sequence:
for n > 2
Step-by-step explanation:
Given the sequence:
7, 6, 13, 19, 32, ......
then;
First term
= 7
Second term 
=6
third term 
= 13 and so on..
You can see that:
similarly for:
and so on..
The recursive rule for this sequence is:
for n > 2

Answer:
I would say A because the real answer is 23.477
Step-by-step explanation:
Answer:
x=8, y=10. (8, 10).
Step-by-step explanation:
-8x+7y=6
3x-2y=4
--------------
2(-8x+7y)=2(6)
7(3x-2y)=7(4)
-----------------------
-16x+14y=12
21x-14y=28
-------------------
5x=40
x=40/5
x=8
3(8)-2y=4
24-2y=4
2y=24-4
2y=20
y=20/2
y=10
