Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
Can you clarify or add a picture?
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
Answer:
Step-by-step explanation:
first, we find the slope
slope = (y2 - y1) / (x2 - x1)
(8,2)....x1 = 8 and y1 = 2
(7,1)....x2 = 7 and y2 = 1
now we sub
slope = (1 - 2) / (7 - 8) = -1/-1 = 1
y = mx + b
slope(m) = 1
use either of ur points...I will use (8,2)...x = 8 and y = 2
now we sub and find b, the y intercept
2 = 1(8) + b
2 = 8 + b
2 - 8 = b
-6 = b
so ur equation is : y = 1x - 6....or just y = x - 6 <===
