F(x) means the function defined at that x value. It really just means what y value when x is equal to that input. So we can see clearly that A is false. They’re nearly opposite y values. B is also obviously false since the y values aren’t equal. C is the same case, the y values aren’t equal. D is true. When x = -2 for both functions, we can see the y value is the same. They also intercept, so that’s a pretty dead giveaway

A gift box’s rectangular base has a perimeter of 92 centimeters. The length of the base is one more than twice the base’s width.

kozerog [31]

Assume that the length of the rectangle is "l" and that the width is "w".

We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II

Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15

Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31

Based on the above calculations:
length of base = 31 cm
width of base = 15 cm

The selling price of an article is Rs 270. If the article was sold at 10 % discount from the marked price, find the marked price

zloy xaker [14]

Answer:

s. p = 270 Rs

discount = 10%

mp.= ?

Mp = s. p + discount

= 270 + 10/100*270

= 270 + 27

= 297 Rs
