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.

[MA]:

-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)

Krys walked 1 1/2 hours longer than Glen.

Step-by-step explanation:

Glen walked 3 miles

3 x 1/4 = 3/4

Krys walked 9 miles

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.

Answer:

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".

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)

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.

The amount of food her dog eat per day would be; 0.33 pound.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that  Debbie’s dog eats 21/5 pounds of dog food every 14 days.  Debbie’s dog eats the same amount of food each day.

Therefore,

21/5 pounds of dog food = 14 day

one day = 14 / (21/5 ) pounds of dog food

One day = 14 x 5/ 21

= 10/3

Therefore, the amount of food her dog eat per day would be; 0.33 pound.
