Find the sum of the first 15 numbers in a sequence that has a1 = 6 and d=4 answers a-62 b-42 c-158 d-510

the correct answer is D. 510

Step-by-step explanation:

158 IS WRONG!

the answer is (-4,-4)

hope this ! : d

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
