describe how you can tell by lookin at a graph of a function which variable is the input variable and which is the output variable
Answers
Answer:
The output variable will be on the y-axis, the input variable will be on the x-axis.
Step-by-step explanation:
To create a function, we must an equation in the form of
[tex]Y(x) = kx + b[/tex]
The x-axis of a graph will be what we change in the function. We will get a certain value ([tex]Y(x)[/tex]) that changes when the right side of the function changes. This means that the input of the function will be [tex]x[/tex].
The y-axis of a graph will be what the x-axis makes. In this case, it's [tex]Y(x)[/tex]. This is the output of the graph after given the input. This means the output is [tex]Y(x)[/tex].

1. How do you identify the terms in an expression? 2. How do you determine the coefficient of a term if you don’t see a number in the term?
Answers
A term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A term in an expression is a set of constant or numerical values, variables, and exponents. Each term of an expression is differentiated from others by a mathematical operation. For example, in the expression 2x²+6x-5, 2x², 6x, and -5 all three are terms and it is differentiated from others by the '+' and '-' operators.
The coefficient of a term is the numerical value present in the term. Let's understand this with the similar example above.
In term 2x², 2 is the coefficient.
In term 6x, 6 is the coefficient.
Hence, a term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.

As LCM ie least common multiple of denominators 10 & 4 = 20
So, multiplying numerator & denominator of [tex]1 / 10[/tex] with 2, we get
[tex]( 1 X 2 ) / ( 10 X 2 ) = 2 / 20[/tex]
Similarly, multiplying numerator & denominator of [tex]1 / 4[/tex] with 5, we get

How do i solve this for g(-3)?
Answers
Answer: g(-3) is 9 .
Step-by-step explanation:
So there are two functions and the first function says that to get the solution x has to be greater than 4 and -3 which is the input is not greater than 4 so you can't use that function to solve for g(-3).
using the second function , it says that x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)
g(x) = -2x + 3 Input -3 and solve
g(-3) = -2(-3) + 3
g(-3) = 6 + 3
g(-3) = 9

Answers
Answer:
B is the right answer.
Step-by-step explanation:
56 + 0.08x = 164
0.08x = 164 - 56
0.08x = 108
0.08x/0.08 = 108/0.08
x = 1,350
To confirm that:
56 + 0.08x
56 + 0.08(1,350)
56 + 108
= 164
164 is the answer.
And your starting fee for five lines is $56, you would start with $56
What I would do is take $164 - $56 to get $108, then proceed to divide that by 0.08 to get 1350, and that would be my x variable
And the equation would be $56 + 0.08x =$164
Meaning the Answer Would Be:
B. 56 + 0.08x = 164, x = 1350

preform the indicated opperation 5 1/6 - -2 2/3
Answers
Answer:
7 5/6
Step-by-step explanation:
Since you're a subtracting a negative, ti cancels each other out and ends up in addition. So it's 5 1/6+2 2/3. And to add fractions the denominators must be the same.
Thus, you multiple 2/3 * 2= 4/6. So 5+2=7.
And 1/6+4/6=5/6.
Therefore the answers is 7 5/6.

midpoint of AB with A(-3, 5) and B(1, 7).
Answers
Answer:
(- 1, 6 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
Here (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(1, 7) , thus
midpoint = [ [tex]\frac{1}{2}[/tex] (- 3 + 1 ), [tex]\frac{1}{2}[/tex] (5 + 7) ] = (- 1, 6 )

sarah is drawing a parallelogram abcd on a coordinate plane. the parallelogram has the coordinates A(-7,5) B(6,5) and D(-9,-2). which of the following coordinates should sarah use for point c?
A. (6,-3)
B. (4,-5)
C. (4,-2)
D. (6,3)
Answers
Answer:
(4,-2)
Step-by-step explanation:
Okay, I figured out the answer...
You need to use the [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex] formula.
We know that AB is parallel to CD....(so whatever answer ad is, then cd will have that same answer).
We also know that AD is parallel to BC...(so whatever answer ad is, then bc will be the same).
So we need to find AB, CD, AD, BC. We have to do CD and BC later because we don't have the c.
Find AB: [tex]\frac{5-5}{6-(-7)}[/tex]= [tex]\frac{0}{13}[/tex]= 0
Find AD: [tex]\frac{-2-5}{-9-(-7)}[/tex] = [tex]\frac{-7}{-2}[/tex]
So now that we have the basic ones, we know that AB is parallel to CD. Therefore CD should have the same slope of 0/13 or 0. SO we need to find numbers that combine with the x and y of AB. When they do combine, they should give a fraction of 0/13.
Find CD: [tex]\frac{-2+2}{-9-4}[/tex] ( we already had the -2...what number adds to -2 to make it zero?...positive 2.....Then, we already had -9 from the D coordinates. So what # adds/subs to -9 to make it 13 or -13...well 4 does. Remember to put the correct signs (-+) in the equation. Our answer is 4,-2). If we had to use positive two, then we take the opposite for our answer. We used -4, so we take the opposite for our answer. Then later on, you can plug in (4,-2) into BC to see if you were to get the slope of -7/-2. which you do.

Find the value of (x) 2x + 2(-3x-5)=26
Answers
Answer:
x = -9
Step-by-step explanation:
Solve for x:
2 (-3 x - 5) + 2 x = 26
2 (-3 x - 5) = -6 x - 10:
2 x + -6 x - 10 = 26
2 x - 6 x = -4 x:
-4 x - 10 = 26
Add 10 to both sides:
(10 - 10) - 4 x = 10 + 26
10 - 10 = 0:
-4 x = 26 + 10
26 + 10 = 36:
-4 x = 36
Divide both sides of -4 x = 36 by -4:
(-4 x)/(-4) = 36/(-4)
(-4)/(-4) = 1:
x = 36/(-4)
The gcd of 36 and -4 is 4, so 36/(-4) = (4×9)/(4 (-1)) = 4/4×9/(-1) = 9/(-1):
x = 9/(-1)
Multiply numerator and denominator of 9/(-1) by -1:
Answer: x = -9

Perimeter = 2* (length + width) so
2(10w + w) = 1540
22w = 1540.
B. 22w = 1540
w = 1540 / 22
w = 70 feet.
