Jax solved an equation and justified his steps as shown below. What reason would justify step 2?
3x + 5 > 2 Step 1: Given
3x > -3 Step 2: ?
x> -1 Step 3: Division Property of Equality
a. Combine Like Terms
b. Division Property of Equality
c. Subtraction Property of Equality
d. Multiplication Property of Equality
Step 2 can be justified using the Multiplication Property of Equality. This property states that if we multiply or divide both sides of an inequality by the same number, the inequality will still hold true.
Explanation:Step 2 can be justified using the Multiplication Property of Equality. This property states that if we multiply or divide both sides of an inequality by the same number, the inequality will still hold true.
In this case, Jax divided both sides of the inequality by 3. This is a valid step because dividing both sides of the inequality by a positive number does not change the inequality. So, by dividing both sides by 3, Jax found that x > -1.

The graph shows the cost for renting a post hole digger from a local hardware store. Determine the rate of change or cost per day.
A) $60 per day
B) $30 per day
C) $90 per day
D) $15 per day
The given graph shows the cost for renting a post hole digger from a local hardware store. We have to determine the rate of change or cost per day.
Let us consider any two points.
Let us consider (1,30) and (2,60)
We have to determine the rate of change which is basically termed as "slope".
Rate of change is expressed as a ratio between a change in one variable relative to a corresponding change in another variable.
Therefore, rate of change or cost per day =
Change in y [tex] \div [/tex] Change in x
= [tex] \frac{60-30}{2-1} [/tex]
= 30
Therefore, the rate of change or cost per day is $30 per day.
Find the greatest common factor : 32a^3b^2, 44ab^3 and 40a^2b
Find the greatest common factor : 25^2q^3, 15p^2q^2 and 35pq^4
Answer:
Part A. 4ab
Part B. 5pq²
Step-by-step explanation:
Part A). In this part the given expressions are 32a³b², 44ab³, 40a²b
We have to find the greatest common factor of these expressions.
Factors of 32a³b² = 2×2×2×2×2×a×a×a×b×b
Factors of 44ab³ = 2×2×11×a×b×b×b
Factors of 40a²b = 2×2×2×5×a×a×b
So for the the greatest common factor we will choose the common factors (bold letters) of three expressions
GCF = 2×2×a×b = 4ab
Part B). The given expressions are 25p²q³, 15p²q² and [tex]35pq^{4}[/tex]
Factors of 25p²q³ = 5×5×p×p×q×q×q
Factors of 15p²q² = 3×5×p×p×q×q
Factors of [tex]35pq^{4}[/tex] = 5×7×p×q×q×q×q
Therefore greatest common factor will be = 5pq²

A job applicant estimates that his chance of passing a qualifying examination is 2/3, and his chance of being appointed if he does pass is 1/4. What is the probability that he will receive the job?
Hence, the probability that he will receive job is:
1/6
Step-by-step explanation:It is given that:
chance of passing a qualifying examination is 2/3=P
and chance of being appointed if he does pass is 1/4=P'
Now, we are asked to find the probability that he will receive the job.
We are asked to find the probability that he will receive the job.
The probability is calculated as:
Probability that he qualify exam×Probability that he is being appointed.
=P×P'
=(2/3)×(1/4)
=1/6

If a force of 60 N is exerted on a 15 kg object, calculate the acceleration that the object undergoes. ________ m/s2 4 900 0.25 40
Answer: The correct option is
(A) 4 m/s.
Step-by-step explanation: We are given that a force of 60 N is exerted on a 15 kg object.
We are to calculate the acceleration that the object undergoes.
From Newton's second law of motion, we have
[tex]F=ma,[/tex] where m is the mass of the object, a is the acceleration and F is the force exerted.
For the given object, we have
F = 60 N and m = 15 kg.
So, we get
[tex]F=ma\\\\\Rightarrow 60=15\times a\\\\\Rightarrow a=\dfrac{60}{15}\\\\\Rightarrow a=4.[/tex]
Thus, the required acceleration that the object undergoes is 4 m/sec.
Option (A) is CORRECT.

Which term describes what a manufacturer spends for goods or services?
a)cost
b)price
c)markup
Pleas help. Willl fan and medal!!
The term describing what a manufacturer spends for goods or services is cost. Cost is the expenses incurred by the manufacturer as a result of his business or undertaking. There are two types of cost of a manufacturer. The cost of goods sold and the operating expenses. The cost of goods sold are those cost incurred directly as a result of manufacturing. The operating expenses are those other expenses not indirectly involved with the manufacture of goods or services.

PLS HELP QUICKLY :V) Anna brings her granddaughter to a photo studio to take spring pictures. For the picture, they have a choice of a background scene, a toy prop, and an outfit. The studio has 12 different background scene, 36 toy props, and 15 outfits to choose from.
How many possible outcomes of a background scene, a toy prop, and an outfit does Anna have?
To calculate the total number of possible outcomes for the photo shoot, you multiply the number of background scenes (12), toy props (36), and outfits (15), which results in 6,480 possible combinations.
The question posed involves determining the number of possible combinations of a background scene, a toy prop, and an outfit in a photo studio with a set number of each option available. To find the total number of possible outcomes, one should multiply the number of choices for each category together. In this case, Anna has 12 different background scenes, 36 toy props, and 15 outfits to choose from.
Therefore, the calculation is as follows:
Number of background scenes: 12
Number of toy props: 36
Number of outfits: 15
By multiplying these numbers, we determine the total number of possible outcomes:
12 (backgrounds) times 36 (props) times 15 (outfits) = 6,480 possible outcomes.
A platform has a volume of 135 cubic feet, but the concrete Joey wants to buy is sold by the cubic yard.
The number of cubic yards of concrete does Joey need to buy is 5 cubic yards.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Given that, a platform has a volume of 135 cubic feet.
One cubic yard is equal to 27 cubic feet.
Now, number of cubic yards
= 135/27
= 5 cubic yards
Therefore, the number of cubic yards of concrete does Joey need to buy is 5 cubic yards.

Two parallel lines are _____ coplanar.
never
sometimes
always
Two lines that lie in parallel planes are _____ parallel.
sometimes
always
never
Please explain the answers, I want to understand this better.
Answer:
1. always
2. sometimes
Step-by-step explanation:
Two lines are coplanar if they lie in the same plane or in parallel planes. There is ALWAYS a plane which contains two parallel lines (see first attached image for details).
Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes [tex]\alpha[/tex] and [tex]\beta[/tex] are parallel. Consider pair of lines [tex]a[/tex] and [tex]a_1[/tex] - they are parallel, but if you consider the pair of lines [tex]a[/tex] and [tex]b_1[/tex], you can see they are not parallel.
Answer:
always
sometimes
Step-by-step explanation:
By definition parallel lines are lines in a plane which do not meet, that means, they have to be coplanar. Coplanar means they are included in the same plane. Then, two parallel lines are always coplanar (imagine two parallel lines in a 3d space, there is always a plane that can contain them).
Two lines that lie in parallel planes are sometimes parallel. As stated before, if there is a third plane which contains the two lines, they can be parallel or cannot, but if there is no plane which contains them, they are not parallel.
