PLEASE HELP ASAP Hi! Please help me guys!!! This is difficult for me.. :c ~Why might a solution to an inequality not be reasonable? Give an example or a counterexample. Thanks! (I'll give brainly!!)
Answer:
When the solution is negative
Step-by-step explanation:
One example, let's say you are buying pens and each pen cost 3 dollars and you cannot spend more than 15 dollars, how many pens can you buy?
The inequality would be 3x < 15, so any negative solution is not reasonable because you cannot buy negative pens. The same goes for most real-world problems dealing with time, money, or distance.

Is 13 a rational number? And why
Answer: A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero if you’re working with a number with a long line of different decimals, then your number is irrational! If you’re working with an integer or a number with terminal or repeating decimals (like 1.333333), then your number is rational! and 13 is a rational number since it can be written as a fraction as well like 13/1

How many integers satisfy the inequality (x 2 – 4)(x 2 – 10) < 0?
Answer:
2 integers (2 and -2)Step-by-step explanation:
Given the inequality (x²– 4)(x² – 10) < 0, we are to find the number of integers that satisfies the inequality
From (x²– 4)(x² – 10) < 0, (x²– 4)< 0 and (x² – 10) < 0
For (x²– 4)< 0;
x²<4
take the square root of both sides;
√x²<√4
x < ±2
x<2 and x<-2
Similarly for (x²– 10)< 0;
x²<10
take the square root of both sides;
√x²<±√10
x < ±√10
x<√10 and x<-√10
Note that √10 is not an integer but an irrational number. An integer should be a negative or positive whole number. Therefore the amount of integers that satisfies the equation is 2 i.e 2 and -2

B - 2

Please help me with this, I'm struggling. In the figure, P||Q. Find m<1.
Answer:
y = 58 x= 122
Step-by-step explanation:
y = 180-90-38+6
x=180-y
Answer:
x = 52º
y = 134º
Step-by-step explanation:
x = 90-38
x = 52º
------------------------------
x + y - 6 = 180º
52 + y - 6 = 180º
y = 180 + 6 - 52
y = 134º

A car travels at a constant speed of 30.0 m/s for 0.8 hr. Find the total distance traveled in km
Answer:
0.8 hr = 0.8*3600 seconds = 2880 seconds
d = 30*2880 meters = 8640 meters
d = 8.64 km
Step-by-step explanation:
hope this helps
The total distance traveled in km is 86.4 km
From the question,
We are to determine the total distance traveled in km.
First, we will determine the distance traveled in m.
Distance traveled can be calculated using the formula
Distance = Speed × Time
From the given information,
Speed = 30.0 m/s
Time = 0.8 hr = 0.8 × 60 × 60 s
Time = 2880 s
Putting the parameters into the formula, we get
Distance = 30.0 × 2880
Distance = 86400 m
Now, we will convert from meters (m) to kilometers (km)
NOTE: 1000 m = 1km
If 1000 m = 1km
Then,
86400 m will be [tex]\frac{86400}{1000}[/tex] km
[tex]\frac{86400}{1000} =[/tex] 86.4 km
Hence, the total distance traveled in km is 86.4 km

Use a number line to add the following: 14 + (-11)
Add.
Adding a negative number is the same as subtracting a positive number.
14 + (-11) = 14 - 11
We start at the point 14 on a number line.
Since we are subtracting, we are going to left -11 units on the number line.
We will land on the point "3"

someone help a-a+b; use a=6 and b=4
Answer:
4
If A=6 then you would have to plug that in for a which would become 6-6 which equals 0.Then you would have to plug in 4 for b so you would do 0+4= your answer of 4.
what are congruent angles written as?
Answer:
Congruent angles are two or more angles that have the same measure. In simple words, they have the same number of degrees. It's important to note that the length of the angles' edges or the direction of the angles has no effect on their congruency. As long as their measure is equal, the angles are considered congruent.
Step-by-step explanation:
hope this helps!
Answer:
Look at the attachment below: that is the congruence symbol.
Suppose you want to write Angle A is congruent to Angle B, then you would write it like this :
∠A ≅ ∠B
Or if you want to write Angle F is congruent to Angle Y, then you would write it like this:
∠F≅∠Y
