Answer:
<em> x = -3</em>
Step-by-step explanation:
A line has equation: y = ax + b
This line has slope a = 1
This line passes (4, 1)
=> 1 = 4 + b
=> b = -3
=> The equation of this line : y = x - 3
This line passes another point (x, -6)
=> -6 = x - 3
=> x = -6 + 3
=> x = -3
Answer:
A percent is a ratio of the parts to the whole
Step-by-step explanation:
If you had 30/100, 30% as a percentage, 30 would be the parts and 100 would be the whole
Answer:
A) 0.15
B) 0.36
Step-by-step explanation:
First Box consist 1 red pills and 19 blue pills
second box consist 6 red pills and 14 blue pills
Third box consist 2 red pills and 18 blue pills
a) Prob ( randomly chosen pill is red) 
b)Prob ( 1 reds and 10 blue pilss) =
First let us find the slope between the two points.
Slope = Change in y / Change in x.
(3, 6) and (8, 4) compares to (x₁, y₁) and (x₂, y₂)
Slope = (y₂ - y₁) / (x₂ - x₁) = (4 - 6) / (8 - 3) = -2/5
Slope m = -2/5= -0.4
Using y = mx + c, using point (3, 6)
y = -0.4x + c
6 = -0.4*3 + c
6 = -1.2 + c
6 + 1.2 = c
7.2 = c
c = 7.2
Equation = : y = -0.4x +c
y = -0.4x + 7.2
y = -4/10 + 72/10
10y = -4x + 72
5y = -2x + 36
Equation =: 5y = -2x + 36
