Answer:

The answer is D

Step-by-step explanation:

- x - equals positive so it would be -8+4r

Answer:

D

Step-by-step explanation:

Honestly I can't giv a detailed explanation, apologies. Negatives multiplied result in positives. Since -4 is negative and -r is also negative, expanded form should be +4r. Also the answer is r=6 in case you need it.

Answer:

$397.85

Step-by-step explanation:

First you need to find Zoey's hourly rate.

Divide 87.20 by 4 and you get 21.8.

Now you just need to time $21.8 by and hours she does.

21.8 x 18.25 = 397.85

Answer: [tex]-x^2-3x+46/x^2+4x-32[/tex]

Step-by-step explanation:

Answer:

  [tex]\dfrac{-x^2-3x+46}{x^2+4x-32}[/tex]

Step-by-step explanation:

You want the simplified form of the rational expression difference ...

  [tex]\dfrac{6}{x^2+4x-32}-\dfrac{x-5}{x-4}[/tex]

Both terms can be expressed using the same denominator, then summed.

  [tex]\dfrac{6}{x^2+4x-32}-\dfrac{x-5}{x-4}=\dfrac{6}{(x-4)(x+8)}-\dfrac{(x-5)(x+8)}{(x-4)(x+8)}\\\\\\=\dfrac{6-(x-5)(x+8)}{(x-4)(x+8)}=\dfrac{6-(x^2+3x-40)}{(x-4)(x+8)}=\boxed{\dfrac{-x^2-3x+46}{x^2+4x-32}}[/tex]

Additional comment

The process is fundamentally identical to finding the difference of numerical fractions. The least common denominator is found by considering factors of the denominators, just as it would be if they were pure numbers.

Answer:

A.

1. no, y = 5 + 3w

B.

no, e = h + 2

Step-by-step explanation:

Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.

Clara's arrangement :

Testing if relationship is proportional :

5 = 3k

[tex] k = \frac{5}{3}[/tex]

Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]

Hector's arrangement :

The number of yellow flowers surpasses the number of white flowers by a constant value of 2.

Hence, the relationship can be modeled thus ;

Therefore, the relationship is not proportional.

Answer:

  1/(x -2)

Step-by-step explanation:

You want the simplified form of the rational expression ...

  [tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8}[/tex]

We simplify this by combining terms over a common denominator, then cancelling any common factors from numerator and denominator.

  [tex]\dfrac{1}{x-4}-\dfrac{2}{x^2-6x+8} = \dfrac{(x-2)}{(x-4)(x-2)}-\dfrac{2}{(x-4)(x-2)}\\\\\\=\dfrac{(x-2)-2}{(x-4)(x-2)}=\dfrac{x-4}{(x-4)(x-2)}=\boxed{\dfrac{1}{x-2}}[/tex]

Note that the domain still excludes x=4, in addition to the obvious exclusion of x=2.

The best statement of the angle-angle similarity theorem is (a) When the preimage of a triangle is a dilation of the image, the triangles are similar.

The angle-angle similarity theorem is used in similar triangles; especially when a triangle is dilated (i.e. resized) to form another triangle

When triangles are dilated, the corresponding angles in both triangles (i.e. the image and the pre-image) are always equal

Hence, the best statement of the angle-angle similarity theorem is (a)

Answer:

1/24

Step-by-step explanation:

chance of rolling 4 - 1/6

Chance of pulling a heart - 13/52, or 1/4

To find P(roll a 4, and pull a heart) you must multiply the 2 answers to find your final answer. So, 1/4 x 1/6 = 1/24

-5 (3 x + 1)

The explanation:

Simplify:

(5 x - 20) + (10 - 15)

Grouping like terms, 5 x - 20 x - 15 + 10 = (5 x - 20 x) + (10 - 15):

(5 x - 20 x) + (10 - 15)

5 x - 20 x = -15 x:

- 15 x + (10 - 15)

10 - 15  = -5:

-5 - 15 x

Factor: -5 out of -15 x - 5:

Answer: -5 (3 x + 1)

Answer:

680 Miles

Step-by-step explanation:

You divide 14 into 476 so you can get the answer for one gallon of gas is however many miles. In this case 1g=34ml. Then you multiply 34 and 20 and you get 680 miles.

53 + 47 = 100

53 + 47 = 100

53 + 47 = 100

53 + 47 = 100

53 + 47 = 100

53 + 47 = 100
