Answer:
-7
Step-by-step explanation:
let the first term be a
thus, a=56
common difference d= U2-U1 = 49-56= -7
Answer:
B : The width of the interval would increase
Step-by-step explanation:
Answer:
y = x + 1
Step-by-step explanation:
Since slope is 1, then the equation will be formatted as y = x+b, since m is 1. Now we need to solve for b, since we're given a coordinate that is on the line, replace x and y for these two points to solve for b.
y = x + b (subsitute)
-1 = -2 + b (add 2 to both sides)
1 = b
So your final equation is y = x + 1.

Answer/Step-by-step explanation:
Given that RP ⟂ QS, <RPS is a right angle.
Therefore, m<RPS = 90°
Since RP bisects <SRQ, therefore m<PRS = ½ of m<SRQ.
Therefore:
m<PRS = ½*104°
m<PRS = 52°
m<S + m<RPS + m<PRS = 180° (sum of ∆)
m<S + 90° + 52° = 180° (substitution)
m<S + 142 = 180°
Subtract 142 from each side
m<S = 180° - 142°
m<S = 38°
