C. 20%
Step-by-step explanation:
50*2=100
40*2=80
100-80=20
A percentage is a number or ratio that represents a fraction of 100.
The percentage decrease in the cost of the pair of pants is 20%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50/100 = 1/2
10% = 10/100 = 1/10
25% = 25/100 = 1/4
20% = 20/100 = 1/5
We have,
The initial cost of pair of pants = $50
The final cost of pair of pants after reduced = $40
The percentage decrease in the cost of pair of pants:
= [( Initial cost - Final cost ) / Initial cost] x 100
= [(50 - 40) / 50] x 100
= (10/50) x 100
= 20%
Thus,
The percentage decrease in the cost of the pair of pants is 20%.

I need help finding the slope, the y-intercept and the equation?
Answer:
y is (0,-2) thats all i know sorry
Step-by-step explanation:
The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.
What is Equation of line?
The equation of line with slope 'm' and y - intercept at point 'b' is given as;
⇒ y = mx + b
Given that;
The points on the graph are (0, 2) and (- 2, 0).
Now,
Since, The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope 'm' is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Thus, The slope of the line with the points (0 , 2) and (-2, 0) is;
m = (0 - 2) / (- 2 - 0)
m = - 2/- 2
m = 1
So, The equation of line passing through the points (0 , 2) and (-2, 0) with slope 1 is defined as;
y - y₁ = m (x - x₁)
y - 2 = 1 (x - 0)
y - 2 = x
y = x + 2
Now, Compare with the equation y = mx + b, we get;
The y - intercept = 2
Thus, The equation of line will be;
⇒ y = x + 2
And, The y - intercept will be 2.

What is the solution to -2(8x-4) is less than 2x+5?
Answer:
=−16x+8 for -2(8x-4)
Step-by-step explanation:
What is the solution to -2(8x-4)= -8x
What is the solution to 2x+5= 7x
so that means -2(8x-4) is less than 2x+5.
Answer: x > 1/6
Step-by-step explanation:
-2(8x - 4) < 2x + 5
Distribute:
-16x + 8 < 2x + 5
Subtract 2x from both sides:
-18x + 8 < 5
Subtract 8 from both sides:
-18x < -3
Divide both sides by -18:
x > 3/18 BUT this simplifies to:
x > 1/6
The reason the inequality flipped is because you divided both sides by a negative number.
The inequality ONLY flips when you divide or multiply both sides by a NEGATIVE number.
