2x + y = 5

Put the coordinates of the points to the equation and check it:

A. 5 - not make sense

B. (1, 2) - x = 1, y = 2

2(1) + 2 = 2 + 2 = 4 ≠ 5 NOT

C. (2, -1) - x = 2, y = -1

2(2) + (-1) = 4 - 1 = 2 ≠ 5 NOT

D. (3, -1) - x = 3, y = -1

2(3) + (-1) = 6 - 1 = 5 YES

<h3>Answer: D. (3, -1).</h3>

1. Now consider equations of the form , where a, b, and c are all positive integers and . (a) Create an equation of this form th

tino4ka555 [31]

a) To create an equation

X+X =7

so what's X over here is

7² = x²

X=3.5

b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.

Explaining the equation:

√5 +√6 = √11

5 +6 = 11

√11 =11

√= 11 ÷ 11

√= 1

So if root is 1 then -1 is -√

this is the answer propably

Snowcat [4.5K]

Answer:

multiplier and multiplicand
factors

Step-by-step explanation:

Different words are used in different contexts. When two numbers are multiplied, one can be identified as the multiplier, and the other the multiplicand.

When two or more numbers or expressions are multiplied, they are often generically referred to as factors. The term factors can also be used to mean prime factors, as when we seek to express a product in terms of its factors.
