So
a be first term and d be common difference
- a+a+2d+a+4d+a+6d+a+9d=17
- 5a+21d=17--(1)
And
- a+d+a+3d+a+5d+a+7d+a+9d=15
- 5a+25d=15--(2)
Eq(1)-Eq(2)
Put in second one
- 5a+25d=15
- a+5d=3
- a+5/2=15
- a=15-5/2
- a=25/2
Answer:
Step-by-step explanation:
c. (18.5-17)/.9= 1.66666666667= 1.6667
d. .7107
e. .2185
f. 0.675=(x-17)/.9 x= 17.6075
Hello there!
The answer is B.
-----------------------------------------------------------------------------------------------------
Explanation and Work:We first must identify if the line goes through the origin or not.
The origin is (0, 0)
The line does go through the origin. This means that there is no y-intercept
The specific equation we would you use would be:
y = kx
K is the constant
We find this by finding the slope.
Slope is found by:
y2 = 2
y1 = 0
x2 = 7
x1 = 0
Now, let's plug in these numbers.
So, now let's plug he slope into our formula.
y =
So, our answer would be B.
I hope I helped!
