Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

        x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..

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).
