Brandon bought a jacket on sale for $36. If the jacket originally cost $60, what was the percentage discount for the cost of the jacket?
Answers
Answer:
40% discount
Step-by-step explanation:
To find this remember the formula [tex]\frac{discount amount}{original price} = \frac{percent discount}{100}[/tex]
To find the discount amount subtract $36 from $60 which is $24.
[tex]\frac{24}{60} = \frac{x}{100}[/tex] next you have to cross multiply
24*100 = 2400 and 60*x = 60x
Now you have the equation 2400 = 60x
Divide both sides by 60 to isolate the variable
x = 40

Is the point (16,20) on line ℓ?
Answers
Answer:
YES
Step-by-step explanation:
Find the equation of the line written as, y = kx. The graph shows a proportional relationship between y and x.
Constant of proportionality/unit rate/slope (k) = rise/run = ⁵/4.
Substitute ⁵/4 in y = kx
We would have:
y = ⁵/4x.
Using the equation of the line, we can know if a given point is on the line by plugging the value of x and y coordinates of the point into the equation. If it makes the equation true, then it is a point on the line. If it doesn't make the equation true, then it isn't a point on the line.
Let's plug in (16, 20) into y = ⁵/4x.
Thus substitute x = 16 and y = 20, we have:
[tex] 20 = \frac{5}{4}(16) [/trex]
[tex] 20 = (5)(4) [/trex]
[tex] 20 = 20 [/trex]
It makes the equation true. Therefore, the point, (16, 20) is a point on line l.

Awnser: Its D uhm yea...
Step-by-step explanation:
The point-slope form of a line is (y-y1)=m(x-x1). Therefore, option C is the correct answer.
Given that, slope (m)=4/5 and the point on line=(-2, 1).
What is the point-slope form of a line formula?A slope is, a numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it (“slope equals rise over run”).
The point-slope form of a line formula is (y-y1)=m(x-x1).
Now, (y-1)=4/5(x+2).
Therefore, option C is the correct answer.
