Answer:
F) y = 7/6 x - 7
Step-by-step explanation:
7x - 6y = 42
making y the subject of formula
7x - 6y = 42
-6y = 42 - 7x
y = - +
( remember - and - gives a positive ( +) )
-42/6 = - 7
therefore the answer is :
y = - 7 +
the answer is
<u>F) y = 7/6 x - 7</u>
Answer:
17900
Step-by-step explanation:
First term a = -19
common difference d = -15-(-19) = 4
number of terms, n = 100
sum of first 100 terms,
n/2(2a+(n-1)d)
= 100/2(2×(-19)+(100-1)4)
= 50×(-38+99×4)
= 50×358
= 17900
