Answer:

f(x)=0 or 8 I'm honestly not sure which but I know one of these is right

Step-by-step explanation:

subtract x^2-2x from both sides -x^2+8x=0

factor left side of the equation x(-x+8)=0

set factors equal to zero

x=0 or x=-x+8=0

x=0 or x=8

Determine the point that lies on the equation y = -5x - 3.

scZoUnD [109]

Answer:

(4, -23)

Step-by-step explanation:

We are given;

The equation, y = -5x -3

We are needed to determine the point that lies on the equation;

We need to know that for a point to be lying on the equation it must satisfy the equation.
This means when we use the value of x in the equation we should get the exact value of y of the given point;

Therefore, in this case;

Point (4, -23)

Replacing x = 4 in the equation;

y = -5(4) - 3

= -23

Therefore, the point lies on the equation as the point satisfies the equation

Thus, the required point is (4, -23)

Answer:

Step-by-step explanation:

$\bigg( \frac{16}{49} \bigg)^{ - \frac{3}{2} } \\ \\ = \bigg( \frac{49}{16} \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}^{2} }{ {4}^{2} } \bigg)^{ \frac{3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ \frac{2 \times 3}{2} } \\ \\ = \bigg( \frac{ {7}}{ {4} } \bigg)^{ 3} \\ \\ = \frac{343}{64} \\$
