Using translation concepts, the graph of g(x) is given as follows:
It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent and translated functions are given, respectively, by:
f(x) = x².g(x) = (x - 5)² + 1.The transformations are as follows:
x -> x - 5, hence the function was shifted right 5 units.y -> y + 1, hence the function was shifted up 1 unit.f(x) has vertex at (0,0), hence g(x) will have the vertex at (5,1). When x = 2, g(x) = (2-5)^2 + 1 = 10, hence the correct statement is:
It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).

2. On Friday, the Lee family had dinner at a
restaurant. They ordered 12 cheeseburgers and
4 chili bowls for $19.40. The following Friday,
the Lee family went back to the same restaurant.
They ordered 8 cheeseburgers and 6 chili bowls
for $16.60. How much does a cheeseburger
cost?
Answer:
cheeseburger costs $1.25
Step-by-step explanation:
let x be the cost of a cheeseburger and y the cost of chilli and set up 2 simultaneous equations, that is
12x + 4y = 19.4 → (1)
8x + 6y = 16.6 → (2)
multiplying (1) by 6 and (2) by - 4 and adding the result will eliminate y
72x + 24y = 116.4 → (3)
- 32x - 24y = - 66.4 → (4)
add (3) and (4) term by term to eliminate y
40x + 0 = 50
40x = 50 ( divide both sides by 40 )
x = 1.25
the cost of a cheeseburger is $1.25
40points! For what value of theta is csc undefined? Thank you!!
A. 0
B. 90
C. 270
D. 315
Because we can't divide by zero, csc(θ) is undefined when θ = 0°, so the correct option is A.
For what value of θ is csc(θ) undefined?First, remember that:
[tex]csc(\theta) = 1/sin(\theta)[/tex]
And also remember that we can't divide by zero.
Then the function csc(θ) is undefined for the values of θ such that sin(θ) = 0.
We know that sin(0°) = 0.
Then csc(0°) is undefined. This means that the correct option is the first one.

solve the inequality
8x - 3 ≥6x + 4
Answer:
Hello! The answer is x ≥ [tex]\frac{7}{2}[/tex].
Step-by-step explanation:
To solve this inequality, we have to get x by itself. To do so, we will rearrange the inequality. To do so, we will subtract 6x from both sides and add 3 to both sides:
8x - 3 ≥ 6x + 4
-6x +3 -6x +3
----------------------
2x ≥ 7
Now, we have to get x by itself and divide both sides by 2 to do so:
2x ≥ 7
-- --
2 2
This leaves us with:
x ≥ [tex]\frac{7}{2}[/tex]
The required solution to the inequality 8x - 3 ≥6x + 4 is x ≥ 3.5.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To solve the inequality, we want to isolate the variable x on one side of the inequality symbol.
8x - 3 ≥ 6x + 4
Subtract 6x from both sides:
2x - 3 ≥ 4
Add 3 to both sides:
2x ≥ 7
Divide both sides by 2:
x ≥ 7/2
Therefore, the solution to the inequality is x ≥ 3.5.

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 9,628(0.92)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years:
r (number of years) 1 2 3 4
g(r) (amount in dollars) 8,972 8,074.80 7,267.32 6,540.59
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer. (5 points)
The percentage given shows that the amount is decreasing by 8%.
How to illustrate the information?From the information given, the function is f(x) = 9,628(0.92)x. This illustrates that the amount is decreasing by 8% she compared to the previous year. This was computed as:
= 1 - 0.92
= 0.08
= 8%
For part B, the percentage change will be:
= (8,972 - 8,074.80)/8972 × 10
= 10%
Therefore, the account recorded a greater percentage change in amount of money over the previous year is account B as 20% is lore than 8%.

From this, we know that y = -1/2 or 2.
However, as distance must be positive, we disregard the negative case, giving us y = 2.

The sum of two numbers is 79. Three times the first number added to 5 times the second number is 283. What are the two numbers?
Answer:
The two numbers are 56 and 23.
Step-by-step explanation:
Let the two numbers be A and B.
We are told that:
A+B = 79, and
2) 3A + 5B = 283
Rearrange the first expression to isolate A:
A = 79-B
Now use this value of B in the second expression:
3A + 5B = 283
3(79-B) + 5B = 283
237-3B + 5B = 283
2B = 46
B = 23
If B=23, we can find A from (1):
A+B = 79
A+23 = 79
A = 56
CHECK:
Does A+B = 79?
56 + 23 = 79? YES
Does 3A + 5B = 283?
3(56) + 5(23) = 283?
168 + 115 = 283? YES

Answer:
(3, - 2 )
Step-by-step explanation:
- 3x - 7y = 5 → (1)
15x + 6y = 33 → (2)
multiplying (1) by 5 and adding to (2) will eliminate x
- 15x - 35y = 25 → (3)
add (2) and (3) term by term to eliminate x
0 - 29y = 58
- 29y = 58 ( divide both sides by - 29 )
y = - 2
substitute y = - 2 into either of the 2 equations and solve for x
substituting into (2)
15x + 6(- 2) = 33
15x - 12 = 33 ( add 12 to both sides )
15x = 45 ( divide both sides by 15 )
x = 3
solution is (3, - 2 )
