What is the value of x in the equation 3x – y = 18, when y = 27?
To find the value of x in the equation 3x - y = 18 when y = 27, substitute 27 for y and solve the resulting equation. The value of x is found to be 15.
The student has asked for the value of x in the equation 3x - y = 18, given that y = 27. To solve for x, we simply substitute 27 for y in the equation and solve for x:
3x - 27 = 18
3x = 18 + 27 (Add 27 to both sides)
3x = 45
x = 45 / 3 (Divide both sides by 3)
x = 15
The value of x is 15 when y = 27.

This is the term in a polynomial without a variable
A term in a polynomial without a variable is known as a constant. It is the term that does not change its value.
Explanation:The term in a polynomial without a variable is often referred to as the constant term. In a polynomial expression, variables are raised to various powers and multiplied by coefficients. However, the constant term is a unique element within the polynomial because it does not involve any variables. It is a number on its own and typically represents the y-intercept of the polynomial graph when plotted on a Cartesian plane.
For example, in the polynomial expression "[tex]3x^2 + 5x - 7,"[/tex] the constant term is "-7." This term contributes a fixed value to the overall expression, regardless of the value of the variable "x." It's a crucial component in polynomial mathematics, as it affects the position of the polynomial graph on the vertical axis. Understanding the constant term is essential for polynomial evaluation, graphing, and solving equations involving these expressions. In essence, the constant term is the base value around which the polynomial varies as the variable changes.

A recipe for lemon cranberry pound cake calls for 80 milliliters of lemon juice and 240 milliliters of plain yogurt. How many liters of lemon juice and yogurt are needed to make 11 cakes?
Answer: 3 liters 520 milliliters
Step-by-step explanation:
Total liquid amount:
80 ml + 240 ml = 320 milliliters
Total amount for 11 cakes:
320 milliliters × 11 = 3,520 milliliters
Total amount for 11 cakes conversion:
3,520 milliliters ÷ 1,000 = 3 remainder 520 = 3 liters 520 milliliters

Answer:
The correct option is (C) Exponential growth.
Step-by-step explanation:
The simplest exponential function is: f(x) = [tex]a^{x}[/tex], a>0, a≠1
If the x is positive then graph of exponential is increasing and if the x is negative then graph of exponential is decreasing.
In given function [tex]f(x)=\frac{1}{2}\times(3)^x[/tex]

A board is leaning against a vertical wall, The board makes a 62 degree angle with the ground and touches the wall at a point that is 45 in, above the ground. What is the length of the board, rounded to the nearest inch?
Answer:
Option C. 51 in.
Step-by-step explanation:
In the given right angle triangle height is given as 45 in. above the ground.
Length of the board is making an angle of 62°with the ground.
Therefore by sine rule
sin 62° = height / hypotenuse
sin 62° = 45/h
0.8829 = 45/h
h = 45/0.8829 = 50.96 ≈ 51 in.
Therefore option C. 51 in. is the answer.
In Emily's physics class, she had to solve the equation 9 = 12at2 + ut for u. Each step of her work is shown below.
Use the drop-down menus to explain each step.
Answer:
[tex]u=(9-\frac{1}{2}at^{2})/t[/tex]
Step-by-step explanation:
we have
[tex]9=\frac{1}{2}at^{2}+ut[/tex]
Solve for u
That means-------> isolate the variable u
step 1
Subtract [tex]\frac{1}{2}at^{2}[/tex] both sides
[tex]9-\frac{1}{2}at^{2}=ut[/tex]
step 2
Divide by [tex]t[/tex] both sides
[tex]u=(9-\frac{1}{2}at^{2})/t[/tex]
In Step 1, Emily subtracts (1/2)at² from both sides to isolate 'u.' In Step 2, she divides both sides by 't' to solve for 'u,' simplification of the equation further.
The equation is 9 = (1/2)at² + ut
Step 1 . 9 - (1/2)at² = ut
In this step, Emily subtracts (1/2)at² from both sides of the equation.
The purpose of this is to isolate the term containing 'u' on the right side of the equation.
Starting with the original equation, Emily recognizes that the term (1/2)at² is added to ut, and she wants to get rid of it from the right side.
To do that, she subtracts (1/2)at² from both sides to keep the equation balanced.
So, she ends up with 9 - (1/2)at² on the left side and ut on the right side.
This is a crucial step because it isolates the term ut, making it easier to solve for 'u' in the next step.
Step 2. [9 - (1/2)at²] / t = u
In this step, Emily divides both sides of the equation by 't' to solve for 'u.' The purpose is to isolate 'u' on the right side of the equation.
Starting with the equation from Step 1 (9 - (1/2)at² = ut), Emily recognizes that she wants to isolate 'u' by itself.
To do that, she divides both sides of the equation by 't.'
This division cancels out 't' on the right side, leaving 'u' alone.
Therefore, simplification of the equation ends up with [9 - (1/2)at²] / t on the left side and 'u' on the right side, this step allows her to find the value of 'u' using the given values of 'a,' 't,' and '9.'

The vertex form of a function is g(x) = (x – 3)2 + 9. How does the graph of g(x) compare to the graph of the function
f(x) = x2?
A.g(x) is shifted 3 units left and 9 units up.
B.g(x) is shifted 3 units right and 9 units up.
C.g(x) is shifted 9 units left and 3 units down.
D.g(x) is shifted 9 units right and 3 units down.
For this case we have that the main function is given by:
[tex]f (x) = x ^ 2[/tex]
First, we apply the horizontal transformation. To do this, we evaluate the function for x-3, that is, we move the graph 3 units to the right.
[tex]f (x-3) = (x-3) ^ 2[/tex]
We apply the vertical transformation. To do this, add to the function 9 units, that is, we move the graph 9 units up.
[tex]f (x-3) +9 = (x-3) ^ 2 + 9[/tex]
We have then:
[tex]g (x) = (x-3) ^ 2 + 9[/tex]
Answer:
B.g (x) is shifted 3 units right and 9 units up.
