Drag and drop the appropriate number, symbol, or variable to each box.

Answers

Answer:

y = -2x + 7

Step-by-step explanation:

you can use y–y1=m(x–x1) but I just plug straight into y=mx+b and solve from their (much simpler)so plugging the numbers in y=mx+b it will become 1 = -2(3) + bsimplify so 1 = -6 +b or b – 6 = 1add six to both sides to get b=7slope or m is -2 and b or y-intercept is 7y= -2x+7

The density of gold is 19.3 grams per cubic centimeter. Rachel determines that the density of a coin is 18.7 grams per cubic centimeter. Based on this evidence, she concludes that the coin is not gold or at least not entirely gold. Is this an example of inductive or deductive reasoning?​

Answers

Answer:

The reasoning is  a deductive.

  The reason is because the pattern of  thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the  gold ) are used to support the conclusion.

Step-by-step explanation:

Gnerally the reasoning is  a deductive.

  The reason is because the pattern of  thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the  conclusion.

Laura works in a furniture store. She earns $160 a week plus 6% of all sales over $2,000. One week in January, Laura’s total sales were $9,400. What were Laura’s earnings for that week?

Answers

$9,400 * 0.06 = $564

$564 + $160 = $724.00

Laura’s earnings for that week were $724.00.

Answer:  $604.00

Step-by-step explanation:

The other answers are paying commission on the whole amount of sales. The question says she earns 6% commission on all sales over $2,000. This would mean she earns commission on $7,400 ($9,400 - $2,000).

$7,400 X 0.06 = $444.00 in commission.

$444.00 + $160 (weekly pay) = $604.00 total earned

Sally is making a scale drawing of her apartment.
• She drew a line measuring 1 1/2 inches to represent the 12-foot width of her living room.
• The length of her living room is 18 feet.

How long a line should Sally draw to represent the length of her living room?

A. 2 inches
B. 2 1/4 inches
C. 2 1/2 inches
D. 3 inches ​

Answers

The answer is B
We know that 1 1/2 is 12 foot
So we divide it by 2 so we know every 6 feet how long is it so we will get 0.75 for each 6 feet.
Now we divide 18ft by 3. We will have three sixs
Now multiple 0.75 by 3 = 2.25 which means the answer is B

What trait do animals and protists have in common? A. both animals and protists are sometimes made up of many cells B. both animals and protists have cells with a nucleus C. neither animals nor protists can make their own food

(Pls answer I’ll mark brainliest

Answers

The answer would be : b

Protozoa are protists that resemble animals. Single-celled eukaryotes called protozoa have several characteristics in common with animals, both animals and protists have cells with a nucleus, hence option B is correct.

What is eukaryotes?

Eukaryota is a varied domain of creatures whose cells have a nucleus, and its members are referred to as eukaryotes. Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures.

They, along with the two categories of prokaryotes, the bacteria and the archaea, make up a significant group of living organism.

A eukaryotic organism that isn't an animal, a plant, or a fungus is considered a protist. Protists do not constitute a natural group, or clade, despite the likelihood that they have a common ancestor with other eukaryotes.

Therefore, option B is correct.

Triangle FUN, with vertices F(−2, 4), U(0, −5), and N(−3, −8) was dilated to form triangle PET with vertices P(−1.6, 3.2), E(0, −4), and T(−2.4, −6.4).Which scale factor was used? A. 1.25

B. −1

C. 2/3

D. 0.8


Suppose these statements about two triangles are
true:∠G=∠S,∠R=∠,and ∠M=∠N. Which statement is correct? Select all that apply.


A.The sides are congruent.


B.The sides are proportional.


C. ΔGRM is similar to ΔNST

D. ΔMGR is similar to ΔNST

Answers

Answer:

For first question answer is D.0.8

For second question answer is D.ΔMGR is similar to ΔNST.

Step-by-step explanation:

Here triangle FUN is dilated to get triangle PET

So, let's take F and P.

F(-2,4) and P(-1.6, 3.2)

Let's find the scale factor by dividing the coordinates.

Scale factor =[tex]\frac{-1.6}{-2} =0.8[/tex]

Using y coordinates of the same points

Scale factor =[tex]\frac{3.2}{4} =0.8[/tex]

So, scale factor is 0.8

Now, for the second problem

<G= <S

<R= <T

<M=<N

So, the corresponding angles are congruent when two triangles similar.

So, we can say ΔMGR is similar to ΔNST.

Miss Bloom's 5 $45.30 on art supplies if she turns 7% tax how much total money did she spend​

Answers

Answer:

l

Step-by-step explanation:

Answer:

Miss Bloom spent $48.47 in total

Step-by-step explanation:

turn 7% into a decimal --> 0.07

multiply the cost of art supplies by the tax % (in decimal form)

45.30(0.07) = 3.171

add 3.171 to the original cost of art supplies

45.30 + 3.171 = 48.471

round to the nearest hundreths place (since money typically only has 2 decimal places)

48.471 --> 48.47

therefore, miss bloom spent $48.47 in total

Step-by-step explanation:

each line equals 180

where H is at, has a 100 above it.

that equals one angle, which is 100. That line has 2 angles at equal 100 since they are one opposite sides of each other.

you subtract 180-100= 80. That's where you get ur 80 angle from. Hope this helps, I'm bad at explaining stuff
