Mathematics
2 answers:
GalinKa [24]3 years ago
7 0

Answer:  A) y = 7x

<u>Step-by-step explanation:</u>

In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates

A) 0 = 7(0)      --->        0 = 0 TRUE

B) 0 = 2 + 3(0) --->       0 = 2 False

C) 0 = Vz(0)    --->        Too many variables so False

D) 0 = 5 - 0    --->         0 = 5 False

Answer:

A, B and D

Step-by-step explanation:

What do you define as proportionality it refers to a relationship; now this relationship is defined as either directly proportional or inversely proportional.

Now take case A; y is directly proportional to X - we say y varies as X varies in a progressive or retrogressive manner .The 7 serves as a constant which comes in handy when ever an equality is been introduced to an item of proportionality.

Also in case B,

As X changes y changes- x is the sole determinant of this y and hence as X increases or decreases y does so likewise.

D ; y decreases as X increases and y increases as X decrease; here the relationship of proportionality is converse . When the graph of D is plotted using any testing values we see that the graph cuts the y axis at 5 and the X axis at 5.

If a rectangle has perimeter of 70 a length of x and a width of x-9, find the value of the length of a rectangle
iren2701 [21]

Answer:

length = 22

width = 13

Step-by-step explanation:

Perimeter of a rectangle is given by the formula

P =2(l+w)

we know the length is x

width is x-9

P =70

Substituting this into the equation

70 = 2(x+x-9)

Combining like terms

70=2(2x-9)

Distributing the 2

70 = 4x-18

Adding 18 to each side

70+18 = 4x-18+18

88 = 4x

Divide by 4

88/4 = 4x/4

22= x

we know the length is x

length = 22

width is x-9

width = 22-9= 13
