Answer:
C. define all variables
Step-by-step explanation:
Equations for word problems will depend on the problem. Not all of the equations will be linear equations. Even if they are, they are not necessarily easily written in any particular form, or easily solved when they are written in that form. The nature of the equations will depend on the problem.
One thing that must be done in any case is define all variables. It is usually a good idea to define the units of the variable(s) as well. Sometimes problems are posed with numbers in incompatible dimensions, or they may ask for an answer in dimensions different from those used in the given information. In order to avoid confusion and to be sure you have the desired answer, you need to make sure the variables and their dimensions are compatible with the solution process.

Find the slope of the tangent line to the graph of each equation at x = 1. y = x3
Answer: the answer is 3
Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3
The slope of the tangent line to the graph of each equation at x = 1. y = 3x will be 3.
What is the slope?A numerical assessment of a line's angle relative to the ground is known as the slope.
The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.
The slope is found by the relation;
[tex]\rm m = \frac{dy}{dx} \\\\ m= \frac{d(3x)}{dx} \\\\ m=3[/tex]
Hence,the slope of the tangent line to the graph of each equation at x = 1. y = 3x will be 3.

The solution of equations system using the Substitution Method
y = 3x & 2y+2x=24 is (3,9)
true
or
false
help mee
Answer:
True
Step-by-step explanation:
[tex] \begin{cases} y = 3x \\\\ 2y + 2x = 24\end{cases} [/tex]
Plugging y = 3x in the equation 2y + 2x = 24, we find:
2(3x) + 2x = 24
6x + 2x = 24
8x = 24
x= 24/8
x = 3
Plugging x = 3 in the equation y = 3x we have:
y = 3*3 = 9
(x, y) = (3, 9)

All of the dimensions of the solid are multiplied by a factor of k=10 how many times greater is the surface area of the new solid? How many times greater is the volume of the new solid?
URGENT PLS PLS PLSPLSOWSOQDNPN
Step-by-step explanation:
The surface area increases by 100
if x y and z are side lengths and it is a rectangle.
Then finding the surface area would normally be 2xy+2yz+2xz
But then increasing each side length by a factor of 10 means multiplying it together
2x(10)y(10)+2y(10)z(10)+2x(10)z(10)
200xy+200yz+200xz and that is 100 times greater than the normal surface area.
Volume:
(x)(y)(z)=normal volume
x(10)y(10)z(10)=increased value
1000xyz=new volume
that is 1000 times greater than the previous volume
Hope that helps :)

Given the following information, find the length of the missing side. Leave your answer as a simplified radical.
Answer:
7√3
Step-by-step explanation:
Given the following information,
Short = 7 = Opposite
Angle of elevation =30 degrees
Required
Long (Adjacent)
Using SOH CAH TOA identity
tan theta = 7/long
tan 30 = 7/long
long = 7/tan30
long= 7/1/√3
long = 7√3
Hence the long is 7√3

Step-by-step explanation:
Amal had a birthday part at the movies. It costs $30 for pizza and $7.50 per friend for the movie tickets. How many friends can Amal have at her party if she has $100?
1) Write an equation that matches this scenario.
2) Define the variable. (What variable are you using and why?)
3) Solve the equation.
Answer:
$100 or y = 7.5x + 30
I used x as it represents the cost of each friend and can be used to solve the total number of friends possible.
She can have 9 friends at her party
Step-by-step explanation:
y = 7.5x + 30
Total Amount + Cost per Friend + Total Cost of Pizza
100 = 7.5x +30
subtract 30 from each side
70 = 7.5x
divide each side by 7.5
9.33 = x

Given the definitions of f(x) and g(x) below, find the value of (g o f) (-3)
f(x)=2x^2+6x+9
g(x)=3x-6
Answer:
21
Step-by-step explanation:
(g o f) (-3) = g ( f(-3) )
First, let's find f(-3):
f(x)=2x²+6x+9
f(-3)=2(-3²)+6(-3)+9
f(-3)=18-18+9
f(-3)=9
Now that we know the value of f(-3), we can sub this into g(f(-3)):
g ( f(-3) ) = g(9)
Find g(9):
g(9)=3x-6
g(9)=3(9)-6
g(9)=27-6
g(9)=21
