Answer:

4

Step-by-step explanation:

they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x

M/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2
m=22.5

6) A demand curve for a product is the number of items the consumer will buy at different prices. At a price of $2 a store can s

ExtremeBDS [4]

Given :

When price is $2 dollars he sells 2400 units .

When price is $8 dollars he sells 600 units .

To Find :

If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.

Solution :

Two points are given :

$(x_1,y_1)=(2,2400)$

$(x_2,y_2)=(8,600)$

Now , slope is given by :

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300$

Now , the equation of line containing these two points and slope -300 is :

$(y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000$

Therefore , equation for the demand curve is $y = -300x +3000$ .

Hence , this is the required solution .

elena-s [515]

Answer:

$1.4*10^7$

Step-by-step explanation:

we have

$14,000,000$

Remember that

$14,000,000=1.4(10,000,000)$

and

$10,000,000=1*10^7=10^7$

substitute

$14,000,000=1.4*10^7$
