Answer:

The standard form of y = 3 x + 1 is         -3x + y = 1 .

The standard form of y  = 4x - 7 is         -4x + y = -7.

Step-by-step explanation:

Here the given equation are:

y = 3 x + 1

and y  = 4x - 7

The above equations are of the form:  y = m x + C

Now, the STANDARD FORM of the equation is Ax + By  = C

<u>Consider equation 1: </u>

y = 3 x + 1

or, y - 3x  = 1

or. -3x + y = 1

⇒ The equation  -3x + y = 1  is in STANDARD FORM.

<u>Consider equation 2: </u>

y = 4 x - 7

or, y - 4x  = -7

or. -4x + y = -7

⇒ The equation -4x + y = -7 is in STANDARD FORM.

Count the number of positive integers less than 100 that do not contain any perfect square factors greater than 1.

Possible perfect squares are the squares of integers 2-9.
In fact, only squares of primes need be considered, since for example, 6^2=36 actually contains factors 2^2 and 3^2.
Tabulate the number (in [ ])of integers containing factors of 
2^2=4: 4,8,12,16,...96 [24]
3^2=9: 9,18,....99  [11] 
5^2=25: 25,50,75  [3]
7^2=49:  49,98 [2]

So the total number of integers from 1 to 99
N=24+11+3+2=40
=>
Number of positive square-free integers below 100 = 99-40 = 59

Answer with Equation. Lisa has a certain amount of money. She spent $90 and has 3/4 left. what was her original price?
andriy [413]
I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90

What numbers add to 2 and multiply to -56
marta [7]

The numbers are irrational, so they can't be exactly written down
using only digits.

In exact form, they are

     1 + √57
and
     1 - √57 .

In rounded form, they are

     8.54983
and
    -6.54983 .
