D: -25/27
-5/6 ÷ 9/10 = 5/6 x 10/9 *when diving fractions, use recipricals.*
-5/6 ÷ 10/9 = - 25/27 *just multiply each numerator and denominator*
Answer:
y = -1/4x-6
Step-by-step explanation:
y=mx+b
Use slope equation m = (y1 - y2) / (x1 - x2)
b is the y intercept : -6
Answer:
its the second one down
Step-by-step explanation:
Answer:I dont know not gonna lie
Step-by-step explanation:
It'd be easier to do #18 if y ou were to break it up:
14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2
14(1+14)
= ---------------- = 7(15) = 105
2
The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.
The final sum is 210 + 14 = 224 (answer)
