Answer:
r = 7
Step-by-step explanation:
In a direct proportionality,
y = rx
Substitute a pair of values for x and y
77 = r × 11
Divide each side by 11
r = 77/11 = 7
slope = (25-4)/(30-10)
slope = 21/20
slope =21/20
using point slope form
y-y1 = m(x-x1)
y-4 = 21/20 (x-10)
y = 21/20x -21/2 +4
y = 21/20 x -21/2 +8/2
y = 21/20x -13/2
let x=40
y = 21/20 (40) -13/2
y = 42-13/2
y = 35.5 games
If we round the slope to 1
slope =1
using point slope form
y-y1 = m(x-x1)
y-4 = 1 (x-10)
y = 1x -10 +4
y = x -6
let x=40
y = 40-6
y = 34 games
Answer:
40°
Step-by-step explanation:
(Linear pair angles)
Answer:
No solution
Step-by-step explanation:
The question is 4(3x-5)=12x-24
so we do the step:12x-20=12x-24
No solution.
