How does y=2x-2 have infinite number of solutions

2 answers:

5 0

If you think about it this way,

Y and X could mean ANYTHING just as long as they are equal to each other.

For example: let x = 2, so 2x-2 =2
Well...set y=2, and there you have it!

Another one: let x = 3, so 2x-2 = 3
Well....set y = 3.....hopefully you get the idea.

Once again....since there are two variables are in one equation, and that equation is not in a system, ANY two values for X and Y will equal the same, but they HAVE to equal.

Hope this helps. :)

This has infinite solutions because x + x - 2 = 2x - 2

It does not matter what number x is

The perimeter of the rectangle below is 134 units. Find the length of side RS. Write your answer without variables

Eddi Din [679]

Answer:

RS = 30 units

Step-by-step explanation:

Given:

Length (PS) = $4y + 1$

Width (PQ) = $3y + 3$

Perimeter = 134 units

Required:

RS (width)

SOLUTION:

Perimeter of a rectangle = 2(length + width)

Plug in the values into the equation

134 = 2[(4y + 1) + (3y + 3)]

134 = 2[4y + 1 + 3y + 3]

134 = 2[7y + 4]

134 = 14y + 8

Subtract 8 from each side of the equation

134 - 8 = 14y

126 = 14y

Divide both sides by 14.

126/14 = 14y/14

9 = y

y = 9

✍️RS = Width (PQ) = $3y + 3$

Plug in the value of y

RS = tex] 3(9) + 3 [/tex]

RS = tex] 27 + 3 [/tex]

RS = 30

Under certain conditions, the number of bacteria present in a colony is approximated by f(t) = Age 0.023t, where t is in minutes

AleksandrR [38]

Answer:

5 min: 3,029,058
10 min: 3,398,220
60 min: 10,732,234

Step-by-step explanation:

The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).

<h3>5 minutes</h3>

The number of bacteria present after 5 minutes is about ...

f(5) = 2.7×10^6×e^(0.023×5) ≈ 3,029,058

<h3>10 minutes</h3>

The number of bacteria present after 10 minutes is about ...

f(10) = 2.7×10^6×e^(0.023×10) ≈ 3,398,220

<h3>60 minutes</h3>

The number of bacteria present after 60 minutes is about ...

f(60) = 2.7×10^6×e^(0.023×60) ≈ 10,732,234
