Answer:
Graph A.
Step-by-step explanation:
Given the inequality: 
Since the sign is "less than or equal to", the line cannot be dotted. Therefore, Options C and D are incorrect.
Since the sign is a "less than" sign, the required region must be below the line. Therefore, the graph which shows the given inequality is Graph A.
Answer:
10.37
Step-by-step explanation:
find the area of the whole rectangle which is 30 then find the area of the circle which is 19.63 then subtract 30-19.63
Answer:
All real numbers greater than or equal to -1 and less than or equal to 2
Step-by-step explanation:
Let
A_1 ------> the area of rectangle
A_2 ----> the area of triangle
we know that

<em>Find out the area of rectangle</em>

<em>Find out the area of triangle</em>

substitute

Simplify

<em>First case (positive value)</em>




<em>Second case (negative value)</em>

Multiply by -1 both sides




therefore
The solution for x is the interval -----> [-1,2]
All real numbers greater than or equal to -1 and less than or equal to 2
Answer:
10
Step-by-step explanation:
Leave the 5 , change division to multiplication and turn the fraction upside down.
5 ×
= 5 × 2 = 10
There are 13 white marbles in the bag.
Step-by-step explanation:
Given,
Total number of marbles = 24
Let,
x represent the number of white marbles.
y represent the number of yellow marbles.
According to given statement;
x+y=24 Eqn 1
x = 2y-9 Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 3

Putting y=11 in Eqn 2

There are 13 white marbles in the bag.
