Answer:
None of the expressions is simplified to 41.
Step-by-step explanation:
You have to follow the P.E.M.D.A.S., this is:
P:Parentheses first.
E:Exponent next.
M:Multiplication.
D:Division.
(Multiplication and Division is whichever come first, from left to right)
A: Addition.
S: Subtraction.
(Addition and Subtraction is whichever come first, from left to right).
<u><em>We are going to analyze every option:</em></u>
1. 10+ 2.4 - 1
First we have to solve the multiplication:
Now we have to solve the addition and subtraction from left to right:
This is not a correct answer.
2. 10+2.(4-1)
We have to solve the parentheses first:
Now the multiplication and then the addition.
This is not a correct answer.
3. (10+23).4-1
We have to solve the parentheses first:
Now the multiplication and then the subtraction:
This is not a correct option.
4.
We have to solve the parentheses first, in the parenthesis first we have to solve: and then do the multiplication.
Now we have to solve the addition and subtraction from left to right:
This expression is not a correct option.
Then none of the expressions is simplified to 41.
Answer:
B, D
Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
- 2x -4y < 12 . . . . choice B
- x +7 > -1 . . . . . . .choice D
