Answer:
4
Step-by-step explanation:
to solve | a | - | b | + | c | we need to plug in the given values
a = -8
b = -5
c = 1
the | | bars mean absolute value which is the exact value a number is away from 0 on a number line. an absolute value has to be positive, not a negative, as you cant be negative spaces away from something. plugging in the values into the equation we have:
| -8 | - | -5 | + | 1 |
the absolute value of -8 is 8, as -8 is 8 units away from 0 on a number line
like wise with -5, the absolute value of -5 is 5, as -5 is 5 units away from 0 on a number line
1 is the absolute value of 1 as its 1 unit away from 0 on a number line
the new expression looks like the following:
8 - 5 + 1
now we just add/subtract
8 -5 = 3
3 + 1 = 4
the solution to this expression is 4
(3,1)
(3 + 7)1 = 10
In this situation, just plug in the values until one works.
B is the correct answer y=x^2
Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).
