Answer:
The inequality which represents the graph is y ≤ -2x + 1 ⇒ A
Step-by-step explanation:
To solve the question you must know some facts about inequalities
- If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line
- If the sign of inequality is > or <, then it represents graphically by a dashed line
- If the sign of inequality is > or ≥, then the area of the solutions should be over the line
- If the sign of inequality is < or ≤, then the area of the solutions should be below the line
Let us study the graph and find the correct answer
∵ The line represented the inequality is solid
∴ The sign of inequality is ≥ or ≤
→ That means the answer is A or B
∵ The shaded area is the area of the solutions of the inequality
∵ The shaded area is below the line
∴ The sign of inequality must be ≤
→ That means the correct answer is A
∴ The inequality which represents the graph is y ≤ -2x + 1
Answer:
$966
Step-by-step explanation:
6/7 = 828/x
Write a proportion.
6x = 7(828) Use cross products.
6x = 5796 Multiply.
x = 966 Divide both sides by 6.

11.25 - 2.75 = 8.50
174 - 72 = 102
102 / 8.50 = 12
They bought 12 tickets
Answer:
12
Step-by-step explanation:
sqrt(144)
What number times itself equals 144
12*12 = 144
-12*-12 =144
Given your choices, your solution is 12
Answer:
The option that no represent a linear function is 
Step-by-step explanation:
we know that
The graph of a linear function is a straight line
The equation of a linear function in slope intercept form is equal to
where
m is the slope
b is the y-intercept
<u><em>Verify each case</em></u>
option 1) we have
This option represent a linear function
where
m=3
b=-2
option 2) we have
This option represent a linear function
where
m=1
b=0
This option represent a linear direct variation function
option 3) we have
This option not represent a linear function
This option represent a exponential function
option 4) we have
This option represent a linear function
where
m=3
b=0
This option represent a linear direct variation function
