Answer:
a + b = 30
ab = 144
b/a = 24/6 -> 4/1 -> 4
(a+b)^2 -> a^2 + 2ab + b^2 = (24+6)^2 -> 24^2 + 2*144 + 6^2 -> 900

Which function has a domain of all real numbers?
A. y = -2(3x)^1/6
B. y = (x +2)1/4
C.y = (2x)^1/3-7
D.y= -x^1/2+5
Answer:
c - (2x)^1/3-7
Step-by-step explanation:
plato
The function [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.
Thus, option (D) is correct.
As, Domain is the input value of the function.
In the function [tex]y= -x^{1/2}+5[/tex] .
The square root is defined for all non-negative real numbers (including zero).
When we subtract this square root from 5, the resulting function has a domain of all real numbers.
In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.
The function can be evaluated for any real number x, making its domain all real numbers.
Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.

what is he slope of the line and y-intercept PLS HELP ME
Answer:
Slope: 0, y-intercept: -1
Step-by-step explanation:
If a line is completely horizontal, the slope is 0. The equation of this line is:
y = 0x - 1 = -1
The slope is 0 and the y-intercept is -1 because that is the y-coordinate this line intercepts with.

Step-by-step explanation:
you dont really need work because its really just substitution.
Write an equation in Slope intercept form of the line that passes through the given points (-3,4) (1,4)
The equation for the line that passes through the point A ( -3 , 4 ) and
B ( 1 , 4 ) is y = 4
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the first point be A ( x₁ , y₁ ) = A ( -3 , 4 )
Let the second point be B ( x₂ , y₂ ) = B ( 1 , 4 )
Now ,
The equation for the line is given by
y - y₁ = m ( x - x₁ )
To find the slope of the line ,
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values , we get
m = ( 4 - 4 ) / 1 - ( - 3 )
m = 0
So , the slope of the line is 0
Now ,
The equation of line will be
y - 4 = 0 ( x - ( -3 ) )
y - 4 = 0
Adding 4 on both sides , we get
y = 4
So , the equation of the line is y = 4

Answer: 7
Step-by-step explanation:
Answer:
30 galllons per minute
Step-by-step explanation:
Ronnie charges his customers a flat fee of $25 to fix a computer. Then, he charges $30 for each hour he spends working on the computer. If his first job cost $175, how many hours did he spend working?
Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
Answer:
7.5
Step-by-step explanation:
Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:
Hours Dollars
0 25 = 25 + 0(20)=25
1 25+20 = 25 + 1(20)=45
2 25+20+20 = 25 +2 (20)=65
3 25+20+20+20 = 25 +3 (20)=85
4 25+20+20+20+20 = 25 +4 (20)=105
5 25+20+20+20+20+20 = 25 +5 (20)=125
......
n 25+n(20)=175
To find how many hours he worked for $175 we solve the equation using inverse operations:
25+n(20)=175
25-25+n(20)=175-25
n(20)=150
n= 7.5 hours

Which of the following representations of ADAL would allow someone to construct a triangle NOT congruent to ADAL?
pls help just telling me how to do it will help to
Answer:
The Pythagorean Theorem can be used to find the length of the legs and hypotenuse of a triangle. While the distance of a vertical or horizontal line can be counted easily, a diagonal line cannot be determined the same way. A diagonal line, such as the line between the two points shown on the graph, is the hypotenuse of an imaginary right triangle. If you draw the legs of the triangle by drawing straight lines through the points on the graph until the lines meet at a point, you can count the distance of the legs and plug those values into the Pythagorean Theorem.
Step-by-step explanation:
In this case, the meeting point of straight lines drawn through the points is
(-3, -4)
and the distances of the legs of the right triangle are 8 and 6. The theorem is
a² + b² = c²
so 8² + 6² = c² to 64 + 36 = c² to 100 = c² and [tex]\sqrt 100 = \sqrt c^{2}[/tex]
so 10 = c
The distance of the line (hypotenuse) is 10.

b.) >-40
c.) x<-40
d.)<-20

Answer:
The answer would be C, hope i helped
Step-by-step explanation:
First you have to get x by itself. So you do 90-90= 0 and 30-90= -60 which gets:
90 - 3/2x < 30 to -3/2x < -60
Then, you do -3/2 - (-3/2)= 0 and do the same to -60. -60 - (-3/2) = -58.5
which makes it look like
X = -58.5
-58.5 is a smaller number than -40 which means, when you fill it in for x it works
-58.5 ≤ -40
