Answer:

Step-by-step explanation:

Factor the numerator(x+7)(x-5). Then factor the denominator(x+7)(x-3). The x+7 in the top and bottom cancel. So you are left with x-5 in the numerator and x-3 in the denominator.

Answer:

On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).

This answer almost coincide with option C. I suppose there was a mistype.

Step-by-step explanation:

The system of equations is formed by:

–x + 2y = 6

4x + y = 3

In the picture attached, the solution set is shown.

The first equation goes through (0, 3) and (2, 4), as can be checked by:

–(0) + 2(3) = 6

–(2) + 2(4) = 6

The second goes through (0, 3) and (0.75, 0), as can be checked by:

4(0) + (3) = 3

4(0.75) + (0) = 3

What is the difference between decimal and binary numbering systems give examples of when you would use each?
vaieri [72.5K]

The difference between decimal and binary system are-

  • The base-10 system, often known as the decimal system, is the oldest and most widely used system of numbers.
  • The binary number system, often known as base 2, is used by computers.
<h3>What is decimal system?</h3>

Our daily use of numbers is based on a decimal number system, which uses 10 digits. A number system in mathematics is thought of as the use of digits or symbols to represent numbers.

  • The binary number system, the decimal number system, the octal number system, and the hexadecimal number system are the four primary varieties of the number system.
  • Given that it was challenging to multiply & divide big numbers by hand in earlier civilizations, this decimal system system is sometimes called as the Hindu-Arabic and Arabic number system.
<h3>What is binary system?</h3>

The base-2 number system is the binary system. That implies that it solely use the digits 0 and 1. The 1 one location is moved to its left into the 2s place when adding one to one, and a 0 is placed in the ones place, yielding the number 10. In such a base-10 system, 10 thus = 10. 10 = 2 in the base-2 system.

  • The place values in a base-2 system begin with ones and progress to twos, fours, then eights as one move to its left.
  • This is due to the base-2 system's foundation in powers of two.
  • A bit is the term for each binary digit.

Therefore, a binary number system only employs two different digits(0 and 1), whereas decimal number system includes ten different digits (ranging from 0 to 9).

Andrei [34K]
Since both is equal to p(a), you can set them as equal to each other:

15 = 2a - 3
18 = 2a
9 = a
