Answer:
( √15 + 8)/7
Step-by-step explanation:
TanA = -√15
.we are to find tan(A-π/4).
In trigonometry
Tan(A-B) = TanA - TanB/1+ tanAtanB
Hence:
tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4
Substitute tan A value into the formula
tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4
tan(A-π/4) = -√15-1/1-√15
Rationalize
-√15-1/1-√15 × 1+√15/1+√15
= -√15-√225-1-√15/(1-√225)
= -2√15-15-1/1-15
= -2√15 -16/(-14)
= -2(√15+8)/-14
= √15 + 8/7
Hence the required value is ( √15 + 8)/7
Answer:
1.1
Step-by-step explanation:
slope = (-4-7)/(-6-4)= -11/-10 = 1.1
I think is c I'm sorry if is wrong
Answer: X = 34
Step-by-step explanation:
Let's solve your equation step-by-step.
x+30=2x−4
Step 1: Subtract 2x from both sides.
x+30−2x=2x−4−2x
−x+30=−4
Step 2: Subtract 30 from both sides.
−x+30−30=−4−30
−x=−34
Step 3: Divide both sides by -1.
−x
−1
=
−34
−1
