Find the slope of the line

Dima020 [189]

Answer:

Slope = $-\frac{3}{14}$

Step-by-step explanation:

We know that:

X₁ = -3

Y₁ = 5

X₂ = 11

Y₂ = 2

And the formula of the slope is:

Slope = $\frac{y_2 - y_1}{x_2 - x_1}$

Therefore:

Slope = $\frac{2-5}{11-(-3)}$

Slope = $-\frac{3}{14}$

Hope this helps!

Twice the difference of a number and 16 is the same as three times a number less than 18

Maksim231197 [3]

Answer:

Step-by-step explanation:

Let x be the "number."

"twice the difference of a number and 16" can be written as:

2(x-16)

"is the same as three times a number less than 18" can be written as:

= 3(x<18)

I wonder if this was meant to say "is the same as three times a number less 18," instead of "less than 18." If so, we would have:

=3(x-18)

1. Using the sentence as written: 2(x-16) = 3(x<18)

2. Using the sentence as amended: 2(x-16) = =3(x-18)

Going with this interpretation:

2(x-16) = 3(x-18)

2x - 32 = 3x - 54

x = 22

Simplify the expression 5+6i/4+6i A) 56-6i/-20 B) -16-6i/-20 C)56-6i/52 D) -16-6i/52

IRISSAK [1]

Answer:

$The\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.$

Option (C) is correct .

Step-by-step explanation:

As the expression given in the question as follows.

$= \frac{5 + 6i}{4 + 6i}$

Now rationalize the expression.

$= \frac{5 + 6i\times 4 - 6i}{4 + 6i\times 4 - 6i}$

Using the formula

a² - b² = (a - b) (a + b)

Using in the above

$= \frac{5 + 6i\times 4 - 6i}{(4)^{2} - (6i)^{2}}$

$= \frac{5\times 4-5\times 6i+6i\times 4-36\ i^{2}}{16 - 36(i)^{2}}$

As i² = -1

$= \frac{20-30i+24i+36}{16 + 36}$

$= \frac{56-6i}{52}$

$Therefore\ the\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.$

Option (C) is correct .
