What is the value of y when x= 2y <br> 4x-3=0.4-2y

erastova [34]

If you are factoring then the answer is 1/7 x (14z-97) but if your simplifying then it’s 2z- 97/7

A rectangle has vertices (8, 6), (4, 6), (8, −4), and (4, −4). What are the coordinates after dilating from the origin by a scal

Mama L [17]

Answer: (12,9), (6,9), (12,-6) and (6,-6)

Step-by-step explanation:

Given: The coordinates of the original rectangle are (8, 6), (4, 6), (8, −4), and (4, −4). We know that the coordinates of the image after dilation from the origin by a scale factor of k is given by:_

$(xy)\rightarrow(kx,ky)$

Then, the coordinates of the image after dilation from the origin by a scale factor of 1.5 are given by:_

(8, 6)→ $(8\times1.5,6\times1.5)=(12,9)$

(4, 6)→ $(4\times1.5,6\times1.5)=(6,9)$

(8, −4) → $(8\times1.5,-4\times1.5)=(12,-6)$

(4, −4)→ $(4\times1.5,-4\times1.5)=(6,-6)$

Hence, the coordinates of the image after dilation from the origin by a scale factor of 1.5 are (12,9), (6,9), (12,-6) and (6,-6).

Ava borrowed some money from her friend in order to help buy a new video game system. Ava agreed to pay back her friend $2 per w

nydimaria [60]

We know that Ava is paying $2 dollars per week so if L is the money that she owes and t is the number of weeks, and I is the initial debt so we can write an equation like:

$L=I-2t$

Now we can replace the info we have to find the value of I so:

$10=I-2(5)$

and we solve for I

$\begin{gathered} I=10+10 \\ I=20 \end{gathered}$

So the final equation will be:

$L=20-2t$

(x-9)(x+9) find the product

klio [65]

Method 1.

Use $(a-b)(a+b)=a^2-b^2$

$(x-9)(x+9)=x^2-9^2=x^2-81$

Method 2.

Use distributive property: (a + b)(c + d) = ac + ad + bc + bd

$(x-9)(x+9)=(x)(x)+(x)(9)+(-9)(x)+(-9)(9)=x^2+9x-9x-81=x^2-81$

The result of dividing 107 by 10^-3 is?10-4. 102.5. 1010. 104.

lora16 [44]

The result of diving 107 by 10⁻³ is (E) 107,000.

<h3>What do we mean by division?</h3>

The division is one of the four basic operations of arithmetic, which are the methods by which numbers are combined to form new numbers.
Addition, subtraction, and multiplication are the other operations.
At the most basic level, the division of two natural numbers is the process of calculating the number of times one number is contained within another.
For example, if 20 apples are distributed evenly among four people, each receives five apples (see picture).

So, we know that 10⁻³ is 0.001.

Now, 107/0.001 = 107,000.

Therefore, the result of diving 107 by 10⁻³ is (E) 107,000.
