If x = -2, which inequality is true?
Answer
F
2x + 6 6
H
-5 + 3x > 1
J
3 – x < 10
Answer:
J
Step-by-step explanation:
If I remember correctly then its J
Answer:
Definitely J.
Step-by-step explanation:
plug in -2 into the where the x is.
so the equation is 3 - -2<10
it becomes 3 +2<10 because the minus and negative signs cancel each other out, making the equation true.
To show -1 + (-6) on the number line, which directions would you move? *
5 points
right one unit, then left 6 units
Answer:
you would move left once, then left again 6 times. so 7 times to the left.
Step-by-step explanation:
You're moving left because you're working with negative numbers, so -1 would be the first step, and then just move 6 times more to the left. When you work with positives you do the same but to the right.
You will have to move left by 6 units.
What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a number line.
The given expression is -
-1 + (-6)
on solving, we get -
- 1 - 6
- 7
You will have to move left by 6 units.
Therefore, you will have to move left by 6 units.

A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
Answer:
a)1 cup of flour
b)67.5 minutes
Step-by-step explanation:
a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?
From the above question, we know that:
27 dinner rolls = 3 cups of flour
9 dinner rolls = x
Cross Multiply
27 rolls × x = 9 rolls × 3 cups
x = 9 rolls × 3 cups/27 rolls
x = 1 cup of flour
Hence, 1 cup of flour is needed to make 9 dinner rolls
b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?
From the above question:
4 km = 18 minutes
15km = x
Cross Multiply
4km × x = 15km × 18 minutes
x = 15km × 18minutes/4km
x = 67.5 minutes
Hence, in a 15km race , it would take her 67.5 minutes to complete her race.

The quadrilateral TOMA on a coordinate plane has the following characteristics.
TA can be represented by the equation y = 4x where −1 ≤ x ≤ 0.
OM can be represented by the equation y = 4x − 16 where 3 ≤ x ≤ 5.
Describe the quadrilateral.
Answer:
trapezoid
Step-by-step explanation:
y = 4x slope = 4
y' = 4x -16 slope = 4
TA // OM
TA: -1 ≤ x ≤ 0 (limited value)
OM: 3 ≤ x ≤ 5
TA and OM limited in different range, their length is not equal
The shape is a trapezoid
Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
Answer:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Step-by-step explanation:
We want to find the equation of the line that is parallel to:
[tex]\displaystyle y=-\frac{2}{3}x[/tex]
And passes through (-3,5).
First, we need to determine the slope of our new line.
Remember that parallel lines have the same slope.
Since the slope of our original line is -2/3, this means that the slope of our new line must also be -2/3.
Now, we can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-3, 5) be (x₁, y₁). By substitution:
[tex]\displaystyle y-(5)=-\frac{2}{3}(x-(-3))[/tex]
Simplify:
[tex]\displaystyle y-5=-\frac{2}{3}(x+3)[/tex]
Distribute:
[tex]\displaystyle y-5=-\frac{2}{3}x-2[/tex]
Add 5 to both sides. So, our equation is:
[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]
Answer:
[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]
Step-by-step explanation:
5 = –⅔[–3] + b
2
[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.

Which number is a factor of 10, but not a multiple of 2
Answer:
Five is as 2 x5=10, but it doest come in the table of 2
Step-by-step explanation:
Peaches are being sold for $2 per pound.The customer created a model to represent the total cost of peaches bought. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?
The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Answer:
B - The values of both x and y will be real numbers greater than or equal to 0.
The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.
Calculations and Parameters:Given that peaches are being sold for $2 per lb.
If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:
y = $2*x
Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Answer:
A). Scale factor = [tex]\frac{1}{4}[/tex]
B). Length of the unknown side = 2.75 feet
Step-by-step explanation:
Part A
Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,
Scale factor = [tex]\frac{\text{Side length of the image}}{\text{Side length of the preimage}}[/tex]
= [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]
= [tex]\frac{4}{16}[/tex]
= [tex]\frac{1}{4}[/tex]
Part B
Scale factor = [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]
[tex]\frac{1}{4}=\frac{\text{Side length of the smaller rectangle}}{11}[/tex]
Therefore, side length of the unknown side = [tex]\frac{11}{4}[/tex] = 2.75 feet

Jada and Noah wanted to find the total volume of a cube and a rectangular prism. They know that the prisms volume is 20 cubic units, and they know that the cube has side lengths of 10 units. Jada says the total volume is 27,000 cubic units. Noah says it is 1,020 cubic units. Do you agree with either of them?
Answer:
Noah answer is the correct answer
Step-by-step explanation:
The solution to the above question is given as:
Total Volume = Volume of the prism + Volume of the cube
Volume of the prism = 20 cubic units
Volume of a cube = (Side length)³
= 10³ = 1000 cubic units
Hence: The total volume =
20 cubic units + 1000 cubic units
= 1,020 cubic units
Therefore, I agree with Noah's answer.

Question: Determine The Value Of X.

Answer:
x = 78
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so the sum of angles is ...
x° +x° +24° = 180°
2x +24 = 180 . . . . . collect terms
x + 12 = 90 . . . . . . . divide by 2
x = 90 -12 . . . . . . . . subtract 12
x = 78

Additional comment
The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.

At a state fair, each person pays $8 for admission plus $2 for each ride. While at the fair, Elizabeth goes on 6 rides. Which expression can be used to find the total amount Elizabeth spends?
Answer:
The expression is given as:
Total amount = 8 + 2x
Total amount = $20
Step-by-step explanation:
Let the number of rides Elizabeth goes on be represented by x
The expression used to find the total amount =
$8 + $2 × x
= 8 +2x
Elizabeth goes on 6 rides
Total amount =
8 + 2 × 6
= 8 + 12
= $20
