Construct the graph of the equation y=kx if it is known that the point B belongs to the graph. The graph of which of these two e
PIT_PIT [208]

Answer:

The graph with B(2,-3) i.e) y=\frac{-3}{2} x goes through the point M(-10,15).

Step-by-step explanation:

Consider M(-10,15) and given that equation is y = kx.

Now, substitute M(-10,15) in the equation

⇒ 15 = k × -10

⇒ k = \frac{15}{-10} = \frac{-3}{2}

⇒ y = \frac{-3}{2} x

Now, check with the given points B(2,-3) and B(3\frac{1}{3} , -2)

1) B(2,-3)

y = \frac{-3}{2} x

⇒(-3) = \frac{-3}{2} × 2

⇒ -3 = -3 ⇒ LHS = RHS

⇒ B(2,-3) is the required point.

2) for b(3\frac{1}{3} , -2)

LHS ≠ RHS.

So,The graph with B(2,-3) i.e) y=\frac{-3}{2} x goes through the point M(-10,15).

A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after
9966 [12]

Answer:

the area after 6 years is  3,473 km^2

Step-by-step explanation:

The computation of the area after 6 years is as follows:

= Area × (1 - decreased percentage)^number of years

= 4,800 km^2 × (1 - 5.25%)^6

= 4,800 km^2 × 0.9475^6

= 3,473 km^2

Hence, the area after 6 years is  3,473 km^2
