Slope of the line passing through points (-6,6) and (4,-7)

castortr0y [4]

The slope of a line is constant because the acceleration is equal to zero.

The slope of a line is always just (y2-y1)/(x2-x1), so in this case:

m=(-7-6)/(4--6)

m=-13/10

m=-1.3

Evaluate i^31 please help

Nadya [2.5K]

ANSWER

${i}^{31} = - i$

EXPLANATION

We want to evaluate

${i}^{31}$

Use indices to rewrite the expression as:

$= {i}^{30} \times i$

We know that

${i}^{2} = - 1$

So we rewrite the expression to obtain;

$= ({ {i}^{2}) }^{15} \times i$

This gives us;

$= {( - 1) }^{15} \times i$

This simplifies to

$= - 1 \times i$

$= - i$

Factor as the product of two binomials x^2-3x-10

cestrela7 [59]

Answer:

(x-5)(x+2)

Step-by-step explanation:

Hello there!

Your expression there has a highest power of $x^{2}$ , so there will be two constants that you need to find.

Your last term is -10, so the constants will have a product of -10. Also your middle term is -3x, so the terms will add up to -3

-5 and 2 fit the mold.

Have a great day!
