A basket holds at most 14 pounds of apples and oranges. There are at least 3
pounds of apples in the basket. This graph shows the system that represents
this scenario, where x is the weight of the apples and y is the weight of the
oranges.
Which point represents a viable solution?
Answer:
D
Step-by-step explanation:
First, there must be at least 3 pounds of apples in the basket. Apples are the first number, so B and D are our options. As it is impossible to have a negative weight of oranges, D is our answer
The point that represents a viable solution is D(4, 3).
What are systems of inequalities?At least two linear inequalities in the same variables make up a system of linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.
The graph shows the system of inequalities:
x + y ≤ 14
x ≥ 3
y ≥ 0
where x is the weight of the apples and y is the weight of the oranges.
We need to find the point that represents a viable solution, which means it should satisfy all three inequalities.
Let's check each option:
A(2, 9):
2 + 9 ≤ 14 (satisfied)
2 < 3 (not satisfied)
9 ≥ 0 (satisfied)
A(2, 9) does not satisfy the second inequality, so it is not a viable solution.
B(3, -2):
3 + (-2) ≤ 14 (satisfied)
3 ≥ 3 (satisfied)
-2 ≥ 0 (not satisfied)
B(3, -2) does not satisfy the third inequality, so it is not a viable solution.
C(1, 14):
1 + 14 ≤ 14 (not satisfied)
1 ≥ 3 (not satisfied)
14 ≥ 0 (satisfied)
C(1, 14) does not satisfy the first inequality, so it is not a viable solution.
D(4, 3):
4 + 3 ≤ 14 (satisfied)
4 ≥ 3 (satisfied)
3 ≥ 0 (satisfied)
D(4, 3) satisfies all three inequalities, so it represents a viable solution.
Therefore, the point that represents a viable solution is D(4, 3).

Answer: 1.23
Step-by-step explanation:
0.3*4.1=
Answer:
It is 1.23
Step-by-step explanation:
When multiplying decimals, multiply it as a whole number, and move the decimal to the left the amount of times it was in the problem.
i.e. .3 times 4.1
.3 has 1 number behind the decimal and 4.1 also has one number behind the answer. This means that you will move the decimal to the left twice in 123.0 to 1.23

A 16-ounce bag of cereal costs about $2.88. What is the unit rade of the cereal?
Answer:
18 cents per ounce
Step-by-step explanation:
The first step is to identify the unit. In this case, you are told you have 16-ounces. Therefore, your unit is an ounce.
To find the price of one ounce, just divide your price of $2.88 by 16.
Unit rate = $2.88 / 16 = 0.18 or 18 cents per ounce.

Which of the following is a point-slope equation for a line with the point
(-2, 4) and a slope of 3?
OA. y- 4 - 3(x+2)
OB. y+2 = 3(x- 4)
OC. y-2 - 3(x- 4)
OD. y- 4 - 3(x- 2)
Answer:
A. y - 4 = 3(x + 2)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line
Plug in the slope and given point:
y - y1 = m(x - x1)
y - 4 = 3(x + 2) is the equation
So, A is the correct answer.
Find the missing values on the diagram below. Assume that each line is evenly divided. I'm pretty confused on the right side of the number line- anyone understand this???
Answer:
A = 72 B = 50% C = 40%
Step-by-step explanation:
Each space on the bottom is worth 10%.
Each space on the bottom is worth 36.
The values of the equations are solved and a = 72 , b = 50 % and c = 40 %
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
On the number line , the values above represents the numbers and the values below represents the percentage pf numbers
So , a = 20 % of the total value of the number line
b = ( 50 - 0 ) % = 50 % of the number line
And , c = 40 % of the number line which is 144
So , 40 % of the total value = 144
Substituting the values in the equation , we get
( 40 /100 ) A = 144
Multiply by 100 on both sides , we get
40A = 14400
Divide by 40 on both sides of the equation , we get
A = 360
So , the total value of the number line is 360
where a = 20 % of the number line
On simplifying the equation , we get
a = ( 20/100 ) 360
a = 20 x 3.6
a = 72
Therefore , a = 72 , b = 50 % and c = 40 %
Hence , the equations are solved
