The points (2,-2) and (-4,13) line on the graph of a linear function of x. Which point also lies on the graph of this function?
Tcecarenko [31]

Answer:

(0, 3) lies on the line joining (2, -2) and (-4, 13).

Step-by-step explanation:

The equation of the line joining the points (2, -2) and (-4, 13) is:

\frac{y+2}{13+2} =\frac{x-2}{-4-2}

\frac{y+2}{15} =\frac{x-2}{-6}

\frac{y+2}{5} =\frac{x-2}{-2}

-2(y + 2) = 5(x - 2)

-2y - 4 = 5x - 10

5x + 2y - 6 = 0

When we substitute x = 0 and y = 3,

5(0) + 2(3) = 0 + 6 = 6

So, (0, 3) lies on the line joining (2, -2) and (-4, 13).

When the exponent blank is applied to a nonzero base, the result is always 1
boyakko [2]

Answer:

zero (0)

when the exponent 0 is applied to a nonzero base, the result is always 1

Step-by-step explanation:

Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:

a^{0} =1 whit a=0

Let's check this property using an example:

We know that a quantity over itself is always 1:  \frac{2}{2} =1

We also know that a base without exponent is always raised to the power 1: 2=2^{1}

Now, according to the division power rule \frac{a^{m} }{a^{n}} =a^{m-n}, so \frac{2}{2} =\frac{2^{1} }{2^{1} } =2^{1-1} =2^{0} =1
