I can’t help you with the first one because I can’t see the choice. I can help you with the second.
For the second one, you can have two ways of doing this:

-225 - (225 x 20% or 0.20)
-225 x (100% - 20%)

However you do it, your answer should be..
*calculating intensifies*
180. So your answer should be $180 for part B.

For part C, they want to know the cost of the coat PLUS the boots during the sale.

So you can do either this:

(225 + 130) x 80% *cuz 100% - 20% is 80%. Don’t ask where the 100% came from cuz I learned this months ago and my brain hates me so-*

Or this: (225 x 80%) + (130 x 80%)

Either way, your answer would have come out to..
*more calculating intensifies*

284. Yeah. Your answer would be $284.

And if you get it wrong, iz my fault :) not urs

state which basic Property of addition or multiplication justifies truth of the mathematical expressions 0+7y+2=7y+2

dlinn [17]

The given equation is:

0 + 7y + 2 = 7y + 2

This equation is showing that addition of 0 leaves the expression unchanged. 0 is known as the Additive Identity this means if we add or subtract 0 from any expression, number or equation the result won't be changed.

Therefore, the equation satisfied the property of Additive Identity of Real Numbers.

Bacteria triples every hour. How much bacteria will there be after two days if they started with 13,000 bacteria.

timofeeve [1]

13,000 • 3 = 1 hour = 39,000
Now we take the one hours worth 39,000 • 48 (hours in two days) = 1,872,000
Hope this helps!

Help please 1. Describe the transformations necessary to transform the graph of

natta225 [31]

Here are all the steps, and what they do:

STEP 1: HORIZONTAL TRANSLATION

We transform

$x^2\mapsto (x-1)^2$

The general transformation is

$f(x)\mapsto f(x+k)$

These transformations translate the graph horizontally, k units to the left if k>0, k units to the right if k<0.

In this case, k = -1, so we translate the original graph 1 unit to the right.

STEP 2: VERTICAL STRETCH

We transform

$(x-1)^2\mapsto 3(x-1)^2$

The general transformation is

$f(x)\mapsto kf(x)$

These transformations stretch the graph vertically. The graph expands if |k|>1, while it shrinks if 0<|k|<1. If k is negative, we also reflect the graph with respect to the x axis.

In this case, k = 3, so we stretch the graph vertically by a factor 3.

STEP 3: VERTICAL TRANSLATION

We transform

$3(x-1)^2\mapsto 3(x-1)^2+4$
