Answer:
The graph is attached down
Step-by-step explanation:
The form of the linear inequality is y < b + m x, where
m is the slope of the lineb is the y-intercept, the point of intersection between the line and the y-axis (0, b)The solution of the inequality is the area under the lineTo find which graph represents the inequality y < -1 + 2x
→ Find the y-intercept (the value of y at x = 0)
∴ b = -1
∴ The y-intercept is (0, -1)
From the given graphs we have two graphs that the line intersected the y-axis at (0, -1)
2nd graph in the 1st row
2nd graph in the 2nd row
∵ The sign of inequality is <
∴ The shaded area must be under the line
∴ The 2nd graph in the 1st row is our answer
The graph which represents the inequality y < -1 + 2x is attached down

Answers
Hey there!
Sorry if I answered your question too late, but here is the answer!
Step-by-step explanation:
Toby will require $2,000 for expenses for one year of college. He plans to enroll for 2 semesters per year, so Toby has to divide $2,000 by 2 to find the expenses for each semester. He can set up the division as $2,000 ÷ 2 or 2 ⟌2,000.
Answer: He will need $1,000 for each semester.

cara is making a beaded necklace for a gift. she wants to spend more than $25 because she doesn´t want to seem like a cheap friend but no more than $60 because she isn´t that good of a friend either.the bead store charges $3 for large beads and $2 for small beads.if she buys 5 large beads, how many small beads can she buy to stay within her budget.
Answers
Answer:
5 small beads!
Step-by-step explanation:
Hey there!
If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.
Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!
I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!

Hint - Find the constant of proportionality first (y/x=k).
Answers
Answer:
Time in hours (x) ==> distance in miles (y)
1 ==> 610
2 ==> 1,220
2.5 ==> 1,525
Note: constant of proportionality is same all through = 610
Step-by-step explanation:
Constant of proportionality = [tex] \frac{y}{x} = \frac{915}{1.5} = 610 [/tex]
To get the y-values (miles) for each given x-value (hours), multiply each x-value by the constant of proportionality, 610. Constant of proportionality is same all through.
Thus,
Time in hours (x) ==> distance in miles (y)
1 ==> 1*610 = 610
2 ==> 2*610 = 1,220
2.5 ==> 2.5*610 = 1,525
Subtract.

Container R holds a solution that is 20% alcohol and Container S holds a solution that is 60% alcohol. How many liters of solution from each container should be used to create 2 liters of solution that is 50% alcohol?
*make two equations*
Answers
Answer:
The number of liters for container R = x = 0.5 liters
The number of liters for container S = y = 1.5 liters.
Step-by-step explanation:
Let the number of liters of container R = x
Let the number of liters of container S = y
We are told in the question : that
Container R holds a solution that is 20% alcohol
= 20% × x = 0.20x
Container S holds a solution that is 60% alcohol.
= 60% × y = 0.60y
How many liters of solution from each container should be used to create 2 liters of solution that is 50% alcohol?
Hence;
x + y = 2 ....... Equation 1
x = 2 - y
0.20x + 0.60y = 2 × 50%
0.20x + 0.60y = 1........ Equation 2
Substitute
2-y for x in Equation 3
0.20(2 - y) + 0.60y = 1
0.40 - 0.20y + 0.60y = 1
Collect like terms
0.40y = 1 - 0.40
0.40y = 0.60
y = 0.60/0.40
y = 1.5 liters
Note that :
x = 2 - y
x = 2 - 1.5
x = 0.5 liters
Therefore,
the number of liters for container R = x = 0.5 liters
the number of liters for container S = y = 1.5 liters.

What is the perimeter of a hexagon with a side length of 31cm?
Answers
Answer:
186cm im pretty sure
Step-by-step explanation:
Answer:
The perimeter is 186 centimeters.
Step-by-step explanation:
The perimeter is the combination of all the side lengths of a figure. So, to figure this one out, it would be:
31 + 31 + 31 + 31 + 31 + 31
Or in simpler terms:
31 times 6.
All you need to do is multiply, and the answer comes out to 186cm

Round 733,712 to the nearest thousand

Answers
Answer:
734,000
Step-by-step explanation:
The thousands digit is the fourth digit from the right (1000) so we start by underlining that digit.
733,712
Look at the digit to the right of the underlined digit. If the number is 5 or more, add one to the underlined digit. Since 7 is 5 or more, we add one to the underlined digit.
All of the digits behind the underlined digits turn to zeros to hold the place values.
