What are you confused by?
x-intercept(s): (1/2, 0) or (0.5, 0)
y-intercept(s): (0, −2)
The product of the slopes of the perpendicular lines must equal -1. Let the unknown slope be m.
(5/4)m = -1
m = -(4/5)
The required equation is of the form:
y = -(4/5)x + b
Plugging in the coordinates of the given point, we get:
5 = -(16/5) + b
b = 8 1/5.
The required equation is therefore:
y = -(4/5)x + 8 1/5
Answer: 0
Step-by-step explanation:
2(2x-4)=4(x-2) - Start off by diong distributive property on both sides
4x-8=4x-8 - Add 8 to both sides toget rid of it
4x=4x - Divide both sides by 4
0 = 0 - The 2 equations are equal therefore the answer is 0
Hope this helps!
Answer:
40 cents.
Step-by-step explanation:
If he has enough money to buy 6 markers ate $3 for 6 then he must have 30/6 * 3
= $15.
So 30 pencils cost 15 - 3 = $12.
Each pencil costs 12/30
= $0.4
= 40 cents.
