Answer:
2x + 5
Step-by-step explanation:
I am assuming you are talking about a linear function. If it is, then the equation would be:
2x + 5.
Hope this helps!
Answer:
[tex]y = 2x + 5[/tex]
Step-by-step explanation:
For this example, I used the slope-intercept form, [tex]y = mx + b[/tex], where m represents the slope and b represents the y-intercept.
In order to find the equation, we must find the slope and y-intercept.
Finding mThe slope can be found with the formula:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex], where the x and y variables represent different x and y values from the given points.
Substituting in values from the points, we get:
[tex]m = \frac{-1 + 9}{-3 + 7}\\\\m = \frac{8}{4}\\\\m = 2[/tex]
Finding bIn order to find the y-intercept, we must substitute the slope back into the original equation:
[tex]y = 2x + b[/tex]
After this, we must also substitute either of the two points. Both will give the correct answer, but (-3, -1) will be used for this example.
[tex]-1 = 2(-3) + b\\-1 = -6 + b\\5 = b[/tex]
Finding the equationAfter this, all that must be done is to substitute the values for b and m back into the original equation.
[tex]y = 2x + 5[/tex]
To check our work, we can substitute in either of the given points. For demonstration purposes, (-7, -9) will be used.
[tex](-9) = 2(-7) + 5\\-9 = -14 + 5\\-9 = -9[/tex]
A company that sells yoga mats estimates its annual profit using the equation below, where x represents the wholesale price in dollars of 1 yoga mat, and P = annual profit in thousands of dollars.
P = 10x? - 280x + 1,600 When the expression on the right side of this equation is factored completely, which best describes the meaning of the factors?
The annual profit is zero at a wholesale price of $80 and zero at a wholesale price of $200.
The annual profit is zero at a wholesale price of $8 and maximized at a wholesale price of $20.
The annual profit is zero at a wholesale price of $80 and maximized at a wholesale price of $200.
The annual profit is zero at a wholesale price of $8 and zero at a wholesale price of $20.
Answer: (d)
Step-by-step explanation:
Given
Annual profit is given by
[tex]P=10x^2-280x+1600[/tex]
When it is factored then,
[tex]\Rightarrow 10x^2-280x+1600=0\\\Rightarrow 10\left( x^2-28x+160\right)=0\\\Rightarrow x^2-20x-8x+160=0\\\Rightarrow x(x-20)-8(x-20)=0\\\Rightarrow (x-8)(x-20)=0\\\Rightarrow x=8,20[/tex]
On factorization, we get that annual profit is zero at a whole prize of $8 and $20.

14 = 7n
help please
Answer:
n = 2
Step-by-step explanation:
divide by 7 on both sides
Answer:
n = 2
Step-by-step explanation:
7n is the same as 7 times value = 14.
You may find the value of n by simply dividing both sides by seven, in order to isolate the variable.
^ 14/7 = 7n/7
^ (simplified) 2 = n or n =2
Therefore:
Your answer is 2 or n's value in this scenario is 2.

Which is the value of this expression when m=3 and n=-5? (6m^-1 n^0)^-3
A:-8
B:-1/8
C:1/8
D:8
Answer:
The answer is C.
Step-by-step explanation:
I would simplify the expression first.
Equation: (6m^-1)^-3
You can get rid of n^0 because that equals 1.
Any expression raised to the power of -1 equals its reciprocal.
Equation: (6/m)^-3
Equation: (m/6)^3
Final Equation: m^3/216
Now, plug in 3.
(3)^3/216.
27/216 = 1/8

Circles A, B, and C overlap. The overlap of circles B and C is labeled x.
Which statements are true about x? Select three options.
x ∈ B ⋃ C
x ∈ B ∩ C
x ∈ A ⋃ C
x ∈ A ∩ C
x ∈ A
Given:
Circles A, B, and C overlap.
The overlap of circles B and C is labeled x.
To find:
The three correct statements about x.
Solution:
It is given that the overlap of circles B and C is labeled x. It means x represent the common elements of B and C.
So, x belongs to the intersection and union of B and C.
[tex]x\in B\cup C[/tex]
[tex]x\in B\cap C[/tex]
Since x is the element of C, therefore it is also the element of A union C.
[tex]x\in A\cup C[/tex]
The overlap of circles B and C is labeled x. It means [tex]x\notin A[/tex]. So,
[tex]x\notin A\cap C[/tex].
Therefore, the correct options are A, B and C.
Answer:
A, B and C.
