Hi there!

$\large\boxed{-18a^{3}c^{3}}$

To solve, keep in mind the following property:

xᵃ · xᵇ = xᵃ⁺ᵇ

We are given:

-3a⁷ (6)c⁷a⁻⁴c⁻⁴

Combine like exponent bases using the property above:

-3(6)a⁷⁻⁴c⁷⁻⁴

Simplify:

-18a³c³

What's the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8)? ANSWERS: A)

zavuch27 [327]

Answer:

B) y = x + 2

Step-by-step explanation:

Coordinates of point C = $(x_1,y_1)=(6,-12)$

Coordinates of point D= $(x_2,y_2)=(10,-8)$

To find the equation of segment CD

Formula : $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute the values in the formula :

$y-12=\frac{-8+12}{10-6}(x-6)$

y-12=x-6

y=x+6

When two lines are perpendicular to each other the product of their slopes is -1

Let the slope of perpendicular line be x

So, -1 \times x = -1

So, x =1

General equation : y = mx+c

So, Option B has slope = 1

So,the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8) is y = x + 2

Tom has 28 milk chocolates and emily has 24 dark chocolates they have to divide these chocolates into small packets that each ha

Nutka1998 [239]

28+24=52
So we make a sum of what's going to equal 52 in small packets.
I found 4x13=52. 13 would be the number of packets......
BUT!! Since it MUST be equal dark and milk and we have 28 and 26,
you would have to eliminate 1 pack because all 4 would be milk chocolate.
So that is only 12 packets.
4 per pack so that would be 2 dark and 2 milk per packet.
