If the point (-2, -4) was reflected in the x-axis and then translates five units right and seven units down, what would be the coordinates of its image?
Answer:
(3,-3)
Step-by-step explanation:
First, plot the ordered pair (-2,-4). Since you're reflecting the ordered pair across the x-axis, change the -4 to a positive 4. Your new ordered pair should be (-2,4). The order pair when reflected across the x-axis is changing the positive or negative of the y value but keeping the x value the same(simple definition). Afterward, move/translate that reflected ordered pair across 5 units to the right which is (3,4). The last step is to translate that order pair 7 units down which will then give you your answer of (3, -3). I hope this helps you, I tried explaining it the best I could!
The coordinates of the image of the point (-2, -4) will be (3, -3).
What is translation of graph?
Function translation takes a function (and its graph) and, by adding and subtraction, moves the graph around the plane without changing its shape.
Given is a point (-2, -4) which is reflected along the x - axis.
Now, when a point is reflected across the x - axis, then its final coordinates will change according to the rule -
(x, y) ↔ (x, -y)
The given coordinates are (-2, -4) which on being reflected across the x - axis will become (-2, 4).
Now, it is given that after reflection, it is translated five units right and seven units down. We can define it by the rule -
(x, y) ↔ (x + 5, y - 7)
So the new coordinates of the image will be -
(-2, 4) ↔ (-2 + 5, 4 - 7) or (3, -3)
Therefore, the coordinates of the image of the point (-2, -4) will be (3, -3).

The mapping diagram above does NOT represent a function since
for each number Jin Set A (the input) there are multiple mappings
from Set A (the input).
Answer:
For each number in set A, there is one mapping from set A (input) to set B (output), so the mapping represents a function
Step-by-step explanation:
The relation is a function if and only if each input value has only 1 output value
Examples:
The relation {(1, 2), (-3, 5), (0, 10)} is a function because every input has only one output, the input 1 has only output 2, the input -3 has only output 5, the input 0 has only output 10The relation {(-1, -2), (3, -5), (-1, 1)} is not a function because the input -1 has two outputs -2 and 1Let us solve the question
Use the given figure to find the inputs and their corresponding outputs
Set A →→→→ Set B
∵ -3 →→→→ 2
∵ -4 →→→→ 4
∵ 9 →→→→ -2
∵ 1 →→→→ 7
∵ Set A is the input and set B is the output
∵ There is only one arrow go from each value in set A to a value in set B
∴ For each number in set A, there is one mapping from set A to set B
∴ The mapping represents a function
For each number in set A, there is one mapping from set A (input) to set B (output), so the mapping represents a function

The fourth and fifth terms of the arithmetic sequence will be 31 and 37, respectively.
What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference. Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The sequence is given below.
13, 19, 25
The first term is 13 and the common difference is given as,
d = 19 - 13
d = 6
Then the fourth term is given as,
⇒ 25 + 6
⇒ 31
Then the fifth term is given as,
⇒ 31 + 6
⇒ 37
The fourth and fifth terms of the arithmetic sequence will be 31 and 37, respectively.

Alexis had a cell phone that cost $65. She recently bought a new phone that cost $79. What was the percent increase in the prices of the phones?
Show your work. Round to the nearest tenth of a percent
Answer:
21.5%
Step-by-step explanation:
% increase = Increase ÷ Original Number × 100.
(sorry if i'm wrong i'm terrible at math)
The percentage increase in price of the phone is equal to 21.5%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: The cost of the old phone as $65 and cost of the new phone as $79
Change in price= 79-65
=$14
Therefore percentage change in price is = 14/65 × 100
=21.5%
Hence, The percentage increase in price of the phone is equal to 21.5%

.The annual yield per orange tree is fairly constant at 270 pounds per tree when the number of trees per acre is 30 or fewer. For each additional tree over 30, the annual yield per tree for all trees on the acre decreases by 3 pounds due to overcrowding. Find the number of orange trees per acre, x, that maximizes the total yield for an acre, T, in pounds. What is the total maximum yield in pounds of oranges
Answer:
The answer is below
Step-by-step explanation:
Let the yield per hectare be Y and the number of orange trees per acre, x. For fewer than or 30 trees there is a yield of 270 pounds per tree, therefore:
Y(x) = 270 for x ≤ 30
If it is more than 30 trees the yield decreases by 3 pounds, hence:
Y(x) = 270 - 3(x - 30) = 360 - 3x for x > 30
The total yield T is given as T(x) = x × Y
T(x) = x × 270 = 270x for x ≤ 30
T(x) = x(360 - 3x) = 360x - 3x² for x > 30
The maximum yield is at T'(x) = 0
T'(x) = 360 - 6x
360 - 6x = 0
6x = 360
x = 360/6
x = 60
T(6) = 360(60) - 3(60²) = 10800 pounds

the graph of linear function g is shown on the grid. What is the zero of g? (-8,3) (-3,-4.5)
Answer:
Zero of the function = (-6, 0)
Step-by-step explanation:
Let the equation of the function given in the graph is,
y = mx + b
where m = slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
b = y-intercept of the line
From the graph attached,
Slope of the line passing through (-8, 3) and (-3, 4.5) = [tex]\frac{-4.5-3}{-3+8}[/tex] = -1.5
y - intercept 'b' = -9
Therefore, equation of the line will be,
y = -1.5x - 9
Function representing this line will be,
g(x) = -1.5x - 9
Zeros of the given function will be,
g(x) = 0 Or x-intercept
-1.5x - 9 = 0
x = -6
Therefore, zero of the given function is (-6, 0).
maria has 15 fewer apps on her phone than orlando. if the total number of apps on both phones is 29, how many apps are on each phone
This is impossible because 15 fewer than 29 is 14 and then she would have to have negative apps.
Step-by-step explanation:
Orlando's number of apps = 22
Maria's number of apps = 7
Given,
Maria has 15 fewer apps on her phone than Orlando.
The total number of apps on both phones is 29.
We need to find out how many apps are on each phone.
What does the term mean?- M fewer than N by 2
This means if N = P then M = P - 2
- M more than N by 2
This means if N = P then M = P + 2
We have,
Total number of apps = 29 _____(1)
Maria has 15 fewer apps on her phone than Orlando.
We can write this as:
Orlando's number of apps = O.
Now,
Maria's number of apps = O - 15
Now,
From (1)
Orlando's number of apps + Maria's number of apps = 29
O + O - 15 = 29
2O - 15 = 29
2O = 29 + 15
20 = 44
O = 44/2
0 = 22
Orlando's number of apps = 22
Maria's number of apps = 22 - 15 = 7
Thus,
Orlando's number of apps = 22
Maria's number of apps = 7

awnser A is incorrect because if you switch out the x for 3 and the y for -8. The equation would look like -3+3×(-8)=21. and after multiplying 3×-8 which equals -24. The equation turns into -3+(-24)=21 . And after adding -3 and -24 you get -27=21
awnser B is correct because if you switch out the x for -3 and the y for 8. The equation would look like -3+3×8=21. After multiplying 3×8 which equals 24. The equation turns into -3+24=21. And after adding -3and 24 which is pretty much subtracting you get 21=21.
