Deniz seviyesinden aşağıya inildikçe yer altındaki sıcaklık her 200 metrede 1 derece artmaktadır. Yer altındaki araştırma yapmak isteyen jeoloji mühendisi Ekrem bey 3 km derinliğe indiğinde sıcaklık 8 derece olarak ölçülüyor. Buna göre, Deniz seviyesindeki sıcaklık kaç derecedir. A) -5 B) -6 C) -7 D) -10

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

x:       y:  

-1         4

0         4

1         6

2         18

3         20  

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
