Mathematics

Answer:

Step-by-step explanation:

Sum = -5

Product = 2*(-3) = -6

Factors = -6 , 1   {-6 + 1 = -5  & -6 *1 = -6}

2m² - 5m -3 = 0

2m² - 6m + m -3 = 0

2m(m - 3) + (m -3) = 0

(m -3)(2m + 1) = 0

m - 3 =  0    or 2m + 1 = 0

    m = 3      or 2m = -1

                          m = -1/2

Ans: m = 3 , (-1/2)

Dora is thinking of a number between 500 and 600
wariber [46]

9514 1404 393

Answer:

  500 ÷ 8 = 62 r 4, for example

Step-by-step explanation:

In order to have a remainder of 4, the divisor must be greater than 4, so could be any of 5, 6, 7, 8, 9.

The corresponding numbers could be any of ...

  504 +5n . . . 0 ≤ n ≤ 19

  502 +6n . . . 0 ≤ n ≤ 16

  501 +7n . . . 0 ≤ n ≤ 14

  500 +8n . . . 0 ≤ n ≤ 12

  508 +9n . . . 0 ≤ n ≤ 10

__

For example, with the divisor being 6, and n=13, the number could be ...

  580 = 6·96 + 4

Help quick please. Order the numbers from least to greatest.
Anastasy [175]

Answer:

-2\frac{1}{4}

Step-by-step explanation:

Mod of any number represents the absolute value of the number.

Therefore, |-2\frac{1}{4}|=2\frac{1}{4} = 2.25

-2\frac{1}{4}=-2.25

|1\frac{1}{4}|=1.25

\frac{3}{4}=0.75

|-1\frac{3}{4}|=1\frac{3}{4}=1.75

-1\frac{1}{4}=-1.25

Now we can arrange these numbers in ascending order.

-2.25 < -1.25 < 0.75 < 1.25 < 1.75 < 2.25

Therefore, -2\frac{1}{4}
