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
7/8 × c ⇒ substitute ⇒ turn 8 into a fraction
7 8 56
___ × ___ = _____ = 7
8 1 8
Your answer is 7
Slope intercept form is y = mx + b, where m is the slope and b is the y-intercept.
We are given the values of m and b. Inserting the given values into the equation gives us:
y = -2x + 4
This is the slope-intercept equation of the line. Let me know if you need any clarifications, thanks!
