Answer:
x=5
Explanation;
y=4 is a horizontal line, and we know this because all we have is the y intercept; 4 (the y-intercept is the point on the line that intercepts the y axis) There is also no x value. This is the equation for a horizontal line:
y=b
B is the y-intercept.
A line perpendicular to a horizontal line would be a vertical line. This is the equation for a vertical line:
x=d
D is the x-intercept (the point on the line that intercepts the x axis)
So to answer the question, we just need to plug the x value of the point (5,2) into x=d.
(5,2)-> 5 is the x coordinate
Therefore, x=5
I hope this helps! Please comment if you have any questions.
Answer:
Rs 19.20
Step-by-step explanation:
Buying price = Rs 20
Profit = 20% = 0.20 × 20 = Rs 4
Selling price = buying price + profit = Rs 20 + Rs 4 = Rs 24
He wants to make a 25% profit.
Let's say he should buy the pen at Rs 'a' in order to make that amount of profit.
∴ a + 
= 24
1.25a = 24
a = 
So he should buy the pen at Rs 19.20
Answer:
19.25
Step-by-step explanation:
To find the area of a triangle, multiply the base by the height, and then divide by 2.
Equation of a horizontal line passing through point (-3, 8) is y = 8.
