On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite

Answer:

b = -a

Step-by-step explanation:

Since a and b are equally distant to zero but in opposite directions, a and b are opposites, or additive inverses.

The sum of additive inverses is zero.

a + b = 0

b = -a

Dylan and his children went into a grocery store and where they sell peaches for $1 each and mangos for $0.50 each. Dylan has $1
mafiozo [28]

Answer:

8 mangoes

Step-by-step explanation:

1) lets create 2 systems of inequalities

where m=# of mangoes

            p=# of peaches

so m+p≥15 and 1m+0.5p≤15

lets substitute "13" in  the m+p inequality to see how many mangoes dylan can buy:

m+(13)≥15

subtract "13" from both sides:

m≥2

now we substitute "13" in the other inequality:

m+0.5(13)≤15

m+6.5≤15

subtract 6.5 from both sides:

m≤8.5

m≥2 and m≤8.5

seeing our restriction, we can buy 8 mangoes (since we can't have 1/2 a mango)

hope this helps!

What is the least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number?
Mrrafil [7]

The least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number is 2018

<h3>What is an Expression ?</h3>

An expression is a mathematical statement consisting of variables , constant and mathematical operators.

The expression given is

(x+1)(x+2)(x+3)(x+4)+2019

To find the minimum value

(x+1)(x+2) = ( x² +3x +2) = ( x +5/2)² - 9/4

(x+3)(x+4) =  (x² +7x +12) = ( x +5/2)² -1/4

(x+1)(x+2)(x+3)(x+4) = (  x +5/2)⁴ - 5/2 ( x +5/2)² +9/16

Considering ( x +5/2)²  = y

(x+1)(x+2)(x+3)(x+4) = y² - 5/2y + 9/16

(x+1)(x+2)(x+3)(x+4) = ( y - 5/4)² - 1

(x+1)(x+2)(x+3)(x+4) = (  ( x +5/2)² -5/4)² - 1

The minimum value when x is a real number is -1

( x +5/2)² -5/4) = 0

-1 +2019 = 2018

x has two possible real solution

and the least possible value of (x+1)(x+2)(x+3)(x+4)+2019 where x is a real number is 2018.
