mai is solving the equation (x-5)=0, she writes that the solutions are x=5 and x=-5. Han looks at her work and disagrees. he says that only x=5 is a solution. who do you agree with? explain your reasoning.
Answer:
Hey there, im assuming the parenthesis are absolute Value
Han is correct!
Step-by-step explanation:
|x-5|=0
possible solution are the opposite of -5, which is 5
|5-5|=0 (true)
If it was -5,
|-5-5|≠0, it equals 10

What is the sum of 1/2 + 1/4?
Answer:
3/4
Step-by-step explanation:
have a great day :D
please PLEASE PLEASE
14, 21
Step-by-step explanation:
Let the two consecutive multiples be 7n and 7(n+1).
Now, it is given that:
(7n)² + [7(n+1)]² = 637
Simplifying,
49n² + (7n+7)² = 637
49n² + 49n² + 2(7n)(7) + 49 = 637
(as (x+y)² = x² + y² + 2xy)
98n² + 98n + 49 = 637
98n² + 98n - 588 = 0
Dividing by 98 to further simplify,
n² + n - 6 = 0
Factorising, we get
n² + 3n - 2n - 6 = 0
n(n+3) - 2(n+3) = 0
(n+3)(n-2) = 0
Therefore we get n = -3 or n = +2.
Hence, we get the consecutive multiples as 14 and 21.
Feel free to ask if you didn't understand any part.
Hope this helps! :D

Answer: 3.8
Step-by-step explanation:first, you need to figure out what side you’re looking for. Side AC is opposite of the angle you’re given. They also give you length of side AB which is 4. That is the hypotenuse (side directly across from right angle). So, you have the hypotenuse, and need the find the opposite side measure. Which option uses opposite and hypotenuse? That’s Sin. So, you would do: sin70 = ? / 4.
sin (of given angle)= opposite / hypotenuse.
Sin (70 degrees) = ? / 4
Then you solve for “?”
Type sin70 into your calculator, then multiply both sides by 4 to get “?” by itself. You should get 3.758770483, which rounds to 3.8

inscribed angle theorem
diagonals of a rhombus are perpendicular.
formed by a tangent and a chord is half the measure of the intercepted arc.
Answer:
B : inscribed angle theorem
Step-by-step explanation:
The missing reason in step 5 is; Inscribed angle theorem.
Inscribed angle theoremWithin the context of circle geometry, an inscribed angle is the angle formed in the interior of a circle as a result of the intersection of two chords on the circumference of the circle.
Put differently, an inscribed angle is defined by two chords of the circle sharing an endpoint.
Ultimately, since the chords LM and MN intersect on the circumference, with LM being the diameter of the circle, then the measure of angle LMN is 90°.

which of the following is a function
Answer:
This question is incomplete since you did not provide the options needed. Anyway, I will give you an explanation that will be useful for you to understand this.
Step-by-step explanation:
Understanding what a function is will allow you to have more clarity when solving the functions exercises and you will be prepared to understand more concepts that surround functions such as domain, image, relative extremes, their representation on the axes, etc.
A function is a relationship between two variables, one independent (x) and the other dependent (y) and for each value of x there corresponds ONE SINGLE VALUE OF y.
For example :
f(x) = 3x2 + 1
A. 118 degrees
B. 180 degrees
C. 64 degrees
D. 62 degrees

Answer:
11
Step-by-step explanation:
Change 2 3/4 to a mixed number.
11/4
Then multiply
11/4 • 4
Get rid of common denominators. Which are the 4s.
So you're left with 11.
Or you could just turn 4 into 4/1.
Which would be 44/4.
Which simplifies to 11.

A hose fills a 10,000-gallon swimming pool at a rate of 10 gallons per minute. what is the domain and range?
Answer:
Domain: 0 minutes to time it takes to fill. Range: 0 to a 10,000 gallons
Step-by-step explanation:
The domain will be from 0 minutes to time it takes to fill i.e., 1000 and range will be from 0 to 10000 gallons.
It is given that a hose fills 10000 gallon swimming pool at rate of 10 gallons per minute.
We have to find the domain and range.
What do you mean by domain and range ?
The domain is the set of all values for which the function is defined and the range of the function is the set of all values that function takes.
As per the question ;
Capacity of swimming pool = 10000 gallons
Rate of filling = 10 gallons per minute
So ;
Time taken in filling the swimming pool will be ;
= 10000 / 10
= 1000 minutes
So ;
The domain will be from 0 to 1000 minutes i.e., time taken to fill the swimming pool.
Whereas ;
The range will be from 0 to 10000 gallons i.e., amount of swimming pool filled.
Thus , the domain will be from 0 minutes to time it takes to fill i.e., 1000 and range will be from 0 to 10000 gallons.
