<h2>
Find slope-intercept structure </h2>
- y=
- m=2/3, b=-8/3
- therefore the slope will be 2/3
To find y-intercept
- let x=0
- 2(0)-3y=8
- -3y=8
- y=-3/8
To find x-intercept
Answer:
7) 1/4, 1/2, 5/8, 3/4, 7/8. This is in the right order.
Answer:
B
Step-by-step explanation:
Answer:
d) 303 8/9
Step-by-step explanation:
4th term = ar^3 and 5th = ar^4 where a = first term and r = common ratio.
So ar^4 / ar^3
= r = 45/-15 = -3.
Working back,:
The first term a = ar^3/ r^3
= -15 / (-3)^3
= -15/-27
= 5/9
Sum of n terms = a * (r^n - 1)/(r-1)
= 5/9 * ((-3)^7 - 1 ) / (-3 -1)
= 303 8/9
