the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.

Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax = 11% * original price = 0.11 * x= 0.11xTips for dinner = 20% * original price = 0.20 * x = 0.2x0.11x + 0.2x = 18.600.31x = 18.60x = 60$60 was the price of Zoe's dinner, before sales tax and tip.Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
1. Sales tax = 11% times original price = 0.11 times x= 0.11x
2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x
3. 0.11x + 0.2x = 18.60
4. 0.31x = 18.60
5. x = 60
6. $60 was the price of Zoe's dinner, before everything else

Answer:
Step-by-step explanation:
domain represents the numbers at the x endpoints of a graph.
on the graph we see that on the left, the line ends when x is -4
on the right, the line ends when x is 4
the domain is
-4, 4
but notice how on the left there is an open circle
this will be written with a parentheses
( -4, 4
and notice how on the right there is a closed circle

Solve 4x + 8y = 16 for x.
O A. x=-8y + 4
O B. x= -2y+ 16
O C. x= -2y+ 4
D. X = 8y + 16
4x + 8y = 16
4x = 16 - 8y
4x = 4 (4 - 2y)
x = 4( 4 - 2y)/4
X = 4 - 2y
X = -2y + 4

Consider the function f(x) = (x+ 1)2 - 1. Which of the following functions stretches
fo) vertically by a factor of 4?
O A) f0 - (/ax+ 1)2 +3
O B) f9 = 1/ax+ 1)2 -4
Oo fo-4(x+ 1)2 - 1
OD) fo = 4(4x+ 1)2- 1
Answer:
C
Step-by-step explanation:
A coefficient of 4 would have to be added in front of (x+1)^2 in order to vertically stretch the function by a factor of 4.
The answer that demonstrates this is choice C: [tex]f(x) = 4(x+1)^2-1[/tex]
The functions stretches vertically by a factor of 4 will be f(x) = 4(x+ 1)² - 1. Then the correct option is C.
What is the equation of the parabola?Let the point (h, k) is the vertex of the parabola and a is the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic function is given below.
f(x) = a(x+ 1)² - 1
If the value of the leading coefficient lies between 0 to 1. Then the parabola is stretched horizontally.
And if the value of the leading coefficient is greater than one. Then the parabola is stretched vertically.
The functions stretches vertically by a factor of 4. Then the value of the leading coefficient is 4. Then the equation will be
f(x) = 4(x+ 1)² - 1
Then the correct option is C.

Which functions are symmetric about the y-axis? Check all of the boxes that apply.
The functions that are symmetric about the y-axis are;
1) The function in the first option; f(θ) = cos(θ)
2) The function in the third option; f(x) = x²
Reason for the above selection;
Definition;
A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x
Analysis of the graphs;
First Function Graph; The graph represents the graph of cos (θ)
∴ The function is f(θ) = cos(θ)
The value of the function when x = π, f(π) = -1
Similarly, the value of the when x = -π, f(-π) = -1
f(π) = f(-π)
∴ f(x) = f(-x)
Therefore; the first function is an even function
Second Function Graph; The function of the graph is x = y²
∴ y = √(x)
The value of the function when x = 4, y = f(4) = 2
However, the when x = -4, f(-4) does not exist
f(4) ≠ f(-4)
∴ f(x) ≠ f(-x)
Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)
Third Function Graph; The function the graph represents is y = x²
The value of the function when x = 2, f(2) = 4
Similarly, the value of the when x = -2, f(-2) = 4
f(2) = f(-2)
∴ f(x) = f(-x)
Therefore; the third function is an even function
From the above, the functions which are symmetric about the y-axis, (even functions) are;
The first and the third functions
