Answer:
angle j = 90
angle k = 29
angle L = 61
Step-by-step explanation:
180 = 90 + (4x-19) + (5x+1)
90 = 9x - 18
108 = 9x
x = 12
The two equations graphs intersect and the points where they are touching are belonging to both graphs therefore solutions for both equations.
(2) points (x,y) are
(-1,0) (-1)^2. +0^2=1; 1=1 ✔️
0=-1+1; 0=0✔️
(0, 1). (0)^2. +1^2=1; 1=1 ✔️
1=0+1; 1=1 ✔️
With 'random sampling' every item in the population has an equal probability of being selected.
Question 5:
x/3=6
x=3(6)
x=18
Question 4:
2.3k=4.83
k=4.83/2.3
k=2.1
Question 6:
y=3/4-1/2
y=1/4
Question 2:
8r=24
r=3
