Explanation:

If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).

Relations 1 and 3 don't have this issue, so they are functions.

Answer:

x= - 5/2

Step-by-step explanation:

Answer:

x = -5/2

Step-by-step explanation:

4 - (2(-5/2) + 4) = 5

4 - (-5 + 4) = 5

4 - (-1) = 5

4 + 1 = 5

Answer:

Step-by-step explanation:

In the given case, we can conclude The customer received one and one-sixth (1 1/6) of a cake.

The question is asking us to determine how much cake the customer received. The phrase 'dos tercios' translates to 'two-thirds' in English. So, the customer received two-thirds of a cake.

Since the customer also received half of a cake, we can add these two quantities together: two-thirds + one-half.

In order to add these fractions, we need a common denominator. The least common multiple of 2 and 3 is 6. So, we can rewrite two-thirds as four-sixths and one-half as three-sixths. Adding these fractions together gives us seven-sixths (or one and one-sixth).

Therefore, the customer received one and one-sixth (1 1/6) of a cake.

Step-by-step explanation:

Answer:

11 hours

Step-by-step explanation:

First, you need to subtract 16.27 from 80.95 to get how many kilograms of dough he had prepared in that amount of time. 80.95-16.27=64.68. Then you would divide 64.68 by 5.88 to find the total amount of hours he worked. 64.68/5.88=11 hours of work.

Answer:    The slope is 1/8

Step-by-step explanation:

Full equation = ( y = 1/8x-1/8)

Answer:

i. 4x² + 96x + 512

ii. 1,092 m²

Step-by-step explanation:

i. [ 36 + 2 (x - 2) ] × [ 20 + 2 (x - 2) ]

= (36 + 2x - 4) (20 + 2x - 4)

= (32 + 2x) ( 16 + 2x)

= 512 + 64x + 32x + 4x²

= 4x² + 96x + 512.

---------------------------------------------------------------------

ii. If x = 5

then 4x² + 96x  + 512

= 4 × 25 + 96 × 5+ 512

= 100 + 480 + 512   (Simple calculation)

= 1,092 m²

Answer:

81/256

Step-by-step explanation:

3/4*3/4*3/4*3/4

first multiply the numerators (3) together, which equals 81

then multiply the denominators (4) together, which equals 256

81/256 can't be simplified further

Answer:

[tex]\frac{3^4}{4^4} =\frac{81}{256}[/tex]

Reasoning:

According to exponent law:

[tex](\frac{a}{b} )^{x} =(\frac{a^x}{b^x} )[/tex]

Now apply this to your problem.

The answer and solution is in the picture

An equation is formed of two equal expressions. The equation that can represent the amount of solution in a small bottle is x=y/8.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the bubble solution in the small bottle be represented by x, while the amount of solution in the big bottle is represented by y. Since the sum of the solution of 8 small bottles is equal to a big bottle. Therefore, the equation can be written as,

The amount of solution in the big bottle) = (Amount of solution in a small bottle)×8

y = 8x

x = y/8

Hence, the equation that can represent the amount of solution in a small bottle is x=y/8.

XY = 16 ft

Step-by-step explanation:

The mid segment DE is half the sum of the parallel bases, that is

[tex]\frac{XY+WZ}{2}[/tex] = 20 ( multiply both sides by 2 to clear the fraction )

XY + WZ = 40

XY + [tex]\frac{3}{2}[/tex] XY = 40 ( multiply through by 2 to clear the fraction )

2XY + 3XY = 80

5XY = 80 ( divide both sides by 5 )

XY = 16

Answer:

2 and 3

Step-by-step explanation:

to be similar, there must have been the same scaling factor applied for length and width.

when going from 2 to 3 the width changes from 5 to 7, that is a changing factor of 7/5 = 1.4

and the length changes by the same factor :

6.5 × 7/5 = 1.3 × 7 = 9.1

Answer:

  16

Step-by-step explanation:

Your weight is (roughly) proportional to the inverse of the square of the distance you are from the center of the earth. If that distance is reduced to 1/4 its previous value, then your weight will be multiplied by the factor ...

  1/(1/4)² = 16

You would weigh 16 times as much.
