This graph shows the solutions to the inequalities y > -1/3x+5 and y<-1/3x-1. Does the system of inequalities have solutions? If so which region contains the solutions?
A. there is no solution
B. there is a solution and its shown by region C.
C. there is a solution and its shown by region B.
D. there is a solution and its shown by region A.
The solution to a system of inequalities is at the point of intersection of the inequalities
The true statement is (a) there is no solution
The inequalities are given as:
[tex]\mathbf{y > -\frac 13x + 5}[/tex]
[tex]\mathbf{y < -\frac 13x - 1}[/tex]
From the given graph, we can see that the lines of the inequalities do not intersect at any point.
This is because both lines are parallel, and they have the same slope.
Since the lines do not intersect, then the system of inequalities do not have a solution.
Hence, the true statement is (a) there is no solution

You are riding a train. Your carry-on bag can weigh no more than 50 pounds. Your bag weighs 38 pounds. Which inequalities represent how much weight you can add to your bag?
w > 50 - 38
50 > W - 38
38 + w< 50
w< 50 - 38
Can you add both a 9-pound laptop and a 5-pound pair of boots to your bag without going over the weight limit?
Yes, the total being added is 4 pounds, which is a solution of the inequality.
No, the total being added is 14 pounds, which is not a solution to the inequality.
Yes, the added weight needs to be less than 38 pounds, and 9 plus 5 is less than 38.
No, the added weight needs to be at least 38 pounds, and 9 plus 5 is less than 38.
Answer:
A. The inequalities are:
[tex]w + 38 \leq 50[/tex]
[tex]38 + w \leq 50[/tex]
[tex]w \leq 50 - 38[/tex]
B. No, the total being added is 14 pounds, which is not a solution to the inequality.
Step-by-step explanation:
Given
[tex]Maximum = 50[/tex]
[tex]Bag = 38[/tex]
Solving (a): Expression that represent the possible additional weight
Represent the additional weight with w
When w is added to the weight of the bag it must not be more than 50;
Not more than means less than or equal to
This is represented by
[tex]w + 38 \leq 50[/tex] or [tex]38 + w \leq 50[/tex]
Make w the subject
[tex]w \leq 50 - 38[/tex]
Solving (b): If 9lb and 5lb is added to the bag, will it go overweight?
First, we need to solve the inequality in (a)
[tex]w \leq 50 - 38[/tex]
[tex]w \leq 12[/tex]
This means that additional weights must not exceed 12 pounds
Adding 9lb and 5lb, we have:
[tex]9 + 5 = 14[/tex]
14 pounds is more than 12 pounds.
Hence: option B answers the question

If you add 42 and 28, you get 70, then you add 49, and you'll get 119. I hope this helps ;)
Answer:
first add 28 and 42 which would be first adding 2 and 8 which is 10 then you carry the one so the you would add 4 +3 because off your 1 thats 7 so now you have 70 so add 70 and 49 and that would be 119 :) hope this helps

Each pound of strawberries sells for $2.50 and each pound of raspberries sells for $3.75. Jack made $225 from selling a total of 65 pounds of strawberries and raspberries. Graphically solve a system of equations in order to determine the number of pounds of strawberries sold, x,x, and the number of pounds of raspberries sold, yy.
Given:
Selling price of each pound of strawberries = $2.50
Selling price of each pound of raspberries = $3.75
Total quantity = 65 pounds
Total sales = $225
To find:
The number of pounds of strawberries sold, and the number of pounds of raspberries sold graphically.
Solution:
Let x be the number of pounds of strawberries and y be the number of pounds of raspberries sold.
According to the question,
Total quantity : [tex]x+y=65[/tex] ...(i)
Total sales : [tex]2.50x+3.75y=225[/tex] ...(ii)
Table of values for equation (i) is
x y
0 65
65 0
Table of values for equation (ii) is
x y
0 60
90 0
Plot these point on coordinate plane and connect them by straight lines as shown in the below graph.
From the graph it is clear that both lines intersect each other at (15,50). So,
[tex]x=15, y=50[/tex]
Therefore, the number of pounds of strawberries sold is 15 and the number of pounds of raspberries sold is 50.
The number of pounds of strawberries sold and the number of pounds of raspberries sold is 15 and 50
The calculation is as follows;here we assume the strawberries be x
and, the raspberries be y
Now
x + y = 65
It can be written as y = 65 - x
2.50x + 3.75y = 225
From the graph we can say that it should be 15 and 50.

Answer:

The value of the inequality equation is x ≥ - 3 1/2
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be A
Now , the value of A is
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
The value of x ≥ - 3 1/2
On simplifying the equation , we get
The value of x ≥ -7/2
Now , converting the number into decimal form , we get
The value of x ≥ -3.5
So , the number x satisfies for all the values that are above -3.5
Therefore , the value of x is greater than all the numbers greater than -3.5
And the graph for x ≥ -3.5 is given below
Hence , The value of the inequality equation is x ≥ - 3 1/2

Answer:
C
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Here diameter = 8 cm , thus r = 8 ÷ 2 = 4 cm , thus
A = π × 4² = 16π cm² → C
Answer:
C
Step-by-step explanation:
The equation of the area of a circle is [tex]\pi r^{2}[/tex].
We already know the diameter is 8, and the radius is half of the diameter, so it would be 4.
[tex]\pi 4^{2}[/tex]. This is our equation now. Now, we need to square 4, and 4x4 is 16.
Since 16[tex]\pi[/tex] and [tex]\pi[/tex]16 are the same, C is the correct answer.
Suppose you have 28 coins that are all dimes and quarters. The total value of the coins is $5.35. Write a system of equations that models this situation and solve the system to find the number of quarters and dimes.
Answer:
1) The system of equations that models this situation is given as follows
0.1·x + 0.25·y = 5.35...(1)
x + y = 28...(2)
2) The number of dimes = 11 dimes
The number of quarters = 17 quarters
Step-by-step explanation:
1) The given parameters are;
The numbers of quarters and dimes = 28
The total value of the coins = $5.25
Let x represent the number of dimes and y represent the number of quarters, and given that a dime = $0.1 and a quarter = $0.25, we have;
The system of equations that models this situation is given as follows
$0.1·x + $0.25·y = $5.35...(1)
x + y = 28...(2)
2) Making y the subject of both equations gives;
From equation (1), we have;
0.1·x + 0.25·y = 5.35
0.25·y = 5.35 - 0.1·x
y = 5.35/0.25 - 0.1/0.25·x = 21.4 - 0.4·x
y = 21.4 - 0.4·x
From equation (2), we have;
x + y = 28
y = 28 - x
Equating both equations to find the common solution, gives;
21.4 - 0.4·x = 28 - x
x - 0.4·x = 28 - 21.4
0.6·x = 6.6
x = 6.6/0.6 = 11
x = 11
The number of dimes = x = 11
y = 28 - x = 28 - 11 = 17
y = 17
The number of quarters = y = 17.
) Complete the equations.
