the answer is root 5 /3 hope this helps
Answer:
b is the correct answer.
Step-by-step explanation:
Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.

Answer:
17/23
Step-by-step explanation:
To find the slope of a line given 2 points, we use the formula
m = (y2-y1)/ (x2-x1)
= (66-15)/(90-21)
= 51/69
Divide the top and bottom by 3 to simplify the fraction
= 17/23
Answer:
Step-by-step explanation:
hello :
note :
for all x in ℝ : 1) sin(x+2kπ) = sinx ...k in Z 2) sin(-x) = -sinx
in this exercice :
sin(-4π-x)= sin(-x) = -sinx because : -4π = 2(-2)π (form : 2kπ when : k=-2)
