The range of which function includes -4?
y= Vx-5
Y=Vx+5
Y= NX + 5
Y= NX+5
[tex]option \: a \: is \: the \: right \: answer \\ y = \sqrt{x} - 5 \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment[/tex]
The range of function y=√x+5 is -4.
What is Domain and Range?A function's range refers to all of the potential values for y.
The formula for determining a function's range is y = f (x). If every x value corresponds to only one y value, the relation is only a function.
As, we know that the Domain is the input values and Range is the output values.
Now, we have range is -4.
First, -4 = √x - 5
-4 + 5 = √x
√x = 1
x = ±1
Second, -4 = √x+ 5
-4 -5 = √x
√x = -9
x = 81
Third, -4 = √(x + 5)
16 = x+ 5
x = 11
Fourth, -4 = √(x -5)
16 = x - 5
x = 21
So, the range of function y=√x+5 is -4.

Step-by-step explanation:
Since these angles are supplementary (meaning they have a sum of 180 degrees) we get 3a + 2a + 4a = 180° which simplifies to 9a = 180 and then a = 20°
Answer:
a = 20
Step-by-step explanation:
The angles form a straight line, which is 180 degrees
3a + 2a + 4a = 180
Combine like terms
9a = 180
Divide by 9
9a/9 =180/9
a = 20

Solve the following equation. Show all work.
4x² - 5 = 76
Answer:
[tex]x_{1} =-\frac{9}{2} \\x_{2} = \frac{9}{2}[/tex]
Step-by-step explanation:
[tex]4x^2 = 76 + 5\\4x^2 = 81\\x^2 = \frac{81}{4}\\ x = |\frac{9}{2}|[/tex]
Answer:
X = 9/2
Step-by-step explanation:
4x² - 5 = 76
4x² = 76 + 5
4x² = 81
4x² = 9²
(2x)² = 9²
2x = 9
X = 9/2
Sara is moving into a new apartment. The Resort complex charges a $600 security
deposit and costs $950 a month for rent. The Uptown Suites Duplex charges a $300
security deposit and costs $1100 a month for rent. After how many months would the
apartments cost the same amount? Which apartment would you recommend Sara move
to if she plans on staying for 6 months? Please show work.
Answer:
The rent is the same when 2 months have passed.
If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.
Step-by-step explanation:
Sara has two options, the resort complex and the uptown suites duplex, which can be represented by functions where "c" is the cost and "t" is the number of months Sara lives on each apartment.
The Resort complex:
[tex]c_{resort}(t) = 600 + 950*t[/tex]
The Uptown Suites Duplex:
[tex]c_{uptown}(t) = 300 + 1100*t[/tex]
To find the number of months she has to live in them in a way that they have the same cost, we need to find the value of t that makes both equations equal, this is done below:
[tex]600 + 950*t = 300 + 1100*t\\1100t - 950t = 600 - 300\\150t = 300\\t = \frac{300}{150} = 2\\[/tex]
The rent is the same when 2 months have passed.
If she intends to live in them for 6 months, the cost of each are:
[tex]c_{resort}(t) = 600 + 950*6 = 6300[/tex]
[tex]c_{uptown}(t) = 300 + 1100*6 = 6900[/tex]
If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.

The graph of f(x) = ax^2 opens upward and is narrower than the graph of g(x) = x^2 . Which of the following could be the value of a?
A. -0.5
B. 6
C. 0.25
D. -2
Answer:
Option C.
Step-by-step explanation:
The given functions are
[tex]f(x)=ax^2[/tex]
[tex]g(x)=x^2[/tex]
It is given that the graph of [tex]f(x)=ax^2[/tex] opens upward and is narrower than the graph of [tex]g(x)=x^2[/tex].
Graph of [tex]f(x)=ax^2[/tex] opens upward, it means coefficient of [tex]x^2[/tex] must be positive.
Graph of [tex]f(x)=ax^2[/tex] is narrower than the graph of [tex]g(x)=x^2[/tex], it means coefficient of [tex]x^2[/tex] must lies between 0 to 1, i.e., [tex]0<|a|<1[/tex].
From the given options, only 0.25 is a positive number whose absolute value lies in between 0 to 1.
Therefore, the correct option is C.
Following are the solution to the graph function:
Given:
Graph function:
[tex]\to f(x)=ax^2\\\\\to g(x)=x^2\\\\[/tex]
Solution:
It is assumed that its graph of [tex]f(x)=ax^2[/tex] is narrower more expands upwards than the graph of [tex]g(x)=x^2[/tex].The graph of [tex]f(x)= ax^2[/tex] expands upward, suggesting that the [tex]g(x)=x^2[/tex] coefficient must be positive.Since the graph of [tex]f(x)=ax^2[/tex] is thinner than that of the graph of [tex]g(x)=x^2[/tex], it implies that the coefficient of [tex]x^2[/tex] has to be between 0 to 1, i.e. [tex]0<|a| <1.[/tex] .Only 0.25 is a positive number with just an absolute value between 0 and 1 among the available alternatives.Therefore, the final answer is "Option C".

The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people who got B's?
Answer:
16 students got an A
Step-by-step explanation:
Set up an equation to compare the ratio to the scores:
[tex]\frac{2}{5} = \frac{x}{40}[/tex]
Cross multiply:
80 = 5x
Divide each side by 5:
x = 16
Now, check if [tex]\frac{16}{40} = \frac{2}{5}[/tex]
16/8 = 2
40/8 = 5
The ratios are the same! Therefore, 16 students got an A!
Hope this helps! Feel free to contact me if you have any questions :)
