Answer:
Step-by-step explanation:
Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. The absolute value of 2 + 7 is 5.
Has two solutions x = a and x = -a because both numbers are at the distance a from 0. ... An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.
Answer:
x=21
Step-by-step explanation:
well, geez - just do the math!
3/7 * 49 = 21
Answer:
The sum of a number, which I have named 'n', and 7 can be written as the expression:
n+7
remember the word 'is' in a written problem indicates where you'll most likely use an =,≥,≤ sign. Since they say that it is 'no more than' we know that n+7 is less than or equal to the given number, so we use '≤'.
n+7≤ 1
Step-by-step explanation:
Are you asking the equation or the answer
X2 + 2x + 10 =0
Can also be written as 2x +2x + 10 =0
4x + 10 =0
4x = -10
x= -10/4
x= -5/2
