Answer:

(5,9) and (5,3)

Step-by-step explanation:

Because the point is (5,6), and the question tells you to plot two points that are three units away from (5,6) but share the same X coordinate.

The X coordinate is 5. And 6 is the Y coordinate, if we do 6-3=2. 6+3=9.

jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take

Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.

A sum of scalar multiples of two vectors (such as au + bv, where a and b are scalars) is called a linear conbination of the vect

belka [17]

Answer:

-4u -5v

Step-by-step explanation:

Let the sum be ...

<3, -27> = a<3, 3> +b<-3, 3>

This resolves to two equations

3 = 3a -3b

-27 = 3a +3b

Adding these together, we get

-24 = 6a

a = -4

Substituting into the second equation gives ...

-27 = 3(-4) +3b

-15 = 3b

-5 = b

The desired linear combination is ...

<3, -27> = -4<3, 3> -5<-3, 3> = -4u -5v

What are the solutions to the equation (x – 6)(x + 8) = 0?

Trava [24]

we know that

When a product of two or more terms equals zero, then at least one of the terms must be zero

we have

$(x-6)(x+8)=0$

We shall solve each term separately

First solution

$(x-6)=0$

Adds $6$ both sides

$(x-6)+6=0+6$

$x=6$

Second solution

$(x+8)=0$

Subtract $8$ both sides

$(x+8)-8=0-8$

$x=-8$

therefore

<u>the answer is</u>

The solutions are

$x=6$

$x=-8$

Which expression is equivalent to (x^4/3 x^2/3) ^1/3

zvonat [6]

Answer:

$x^{\tfrac 23}$

Step by step explanation:

$\left(x^{\tfrac 43} \cdot x^{\tfrac 23} \right)^{\tfrac 13}\\\\\\=\left(x^{\tfrac 43 + \tfrac 23} \right)^{\tfrac 13}\\\\\\=\left(x^{\tfrac 63} \right)^{\tfrac 13}\\\\\\=\left(x^2 \right)^{\tfrac 13}\\\\\\=x^{\tfrac 23}$
