Reflect (4,3) across the x-axis. Then reflect the result across the y-axis. What are the coordinates of the final point
Answer: (-4,-3)
Step-by-step explanation:
(4,3) quadrant 1
(-4,3)quadrant 2 wasn't used in this
(4,-3) quadrant 3
(-4,-3)Quadrant 4
just trust me and I don't know how this is
college homework lol but okay
Reflection involves mirroring a point over a line. When (4,3) is reflected across the x and y axes, the final point is (-4,-3)
Given that
[tex](x,y) = (4,3)[/tex]
The rule of reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex](4,3) \to (4,-3)[/tex]
The rule of reflection across the y-axis is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
[tex](4,-3) \to (-4,-3)[/tex]
Hence, the final point of (4,3) is (-4,-3)

10. Carl wants to buy a television that costs $400,
including taxes. To pay for the television, he will use
a payment plan that requires him to make a down
payment of $150, and then pay $70.50 each month
for 6 months. What is the percent increase from the
original cost of the television to the cost of the
television using the payment plan?
Calculate the total he will pay:
70.50 x 6 months = 423
423 + 150 = 573
He pays a total of 573
Find the difference from what he pays to what the actual price was:
573 - 400 = 173
Divide the difference by the actual price:
173 / 400 = 0.4325
Multiply by 100:
0.4325 x 100 = 43.25% increase
Which equation represents the function graphed on the
coordinate plane?
O g(x) = x + 1 + 3
O g(x) = x + 3 - 1
O g(x) = |x-1| + 3
O g(x) = x + 3 + 1
Answer:
it is the third option of g(x)=|x-1|+3x-1
the way I look at this is by visualizing the translations using the parent function of f(x)=|x|
the function moved up three and to the right by one which led to my conclusion
The equation that represents the function graphed on the coordinate plane is y = |x - 1| + 3.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to find the equation that represents the function graphed on the coordinate plane.
The parent function for the given function is -
y = |x|
The function rule for transformation can be written as -
(x, y) : (x - 1, y + 3)
So, we can write the function after transformation as -
y = |x - 1| + 3
Therefore, the equation that represents the function graphed on the coordinate plane is y = |x - 1| + 3.

A maintenance technician sights the top of a telephone pole at a 25° angle of elevation as shown. Technician Telephone Pole Determine the horizontal distance between the technician and the base of the telephone pole to the nearest tenth of a foot. Enter your answer in the box.
Answer:
[tex]x = 375.3[/tex]
Step-by-step explanation:
Given
See attachment for illustration
Required
Determine the horizontal distance
The horizontal distance is the distance between the technician and the base of the pole.
Represent this with x.
The relationship between x, 175ft and 25 degrees is represented as:
[tex]tan(25^{\circ}) = \frac{175}{x}[/tex] --- i.e. tan formula
Multiply both sides by x
[tex]x * tan(25^{\circ}) = \frac{175}{x} * x[/tex]
[tex]x * tan(25^{\circ}) = 175[/tex]
Make x the subject
[tex]x = \frac{175}{tan(25^{\circ})}[/tex]
[tex]x = \frac{175}{0.4663}[/tex]
[tex]x = 375.294874544[/tex]
[tex]x = 375.3[/tex] --- approximated
The distance is approximately 375.3ft

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 2(m∠Y) − 75°. Find m∠Y.
m∠s + m∠y = 90
m∠s = 90 - m∠y
m∠s= 2(m∠y) - 75
90 - m∠y = 2 m∠y -75
90 + 75 = 3 (m∠y)
165 = 3 (m∠y)
55= m∠y
The following exchange rate is given: £1 = 1.33 dollars. Convert £8 into dollars.
If £1 = $1.33, £8 is $10.64.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
£1 = $1.33
Multiply 8 on both sides.
£8 = 8 x $1.33
£8 = $10.64

Explain the steps of how you would find the value of x.
What is the value of x?
How do you know that your answer is correct? How can you prove that?
Answer:
-3+13x=9.
13x=9+3
13x=12
x=12/13
i proved it by putting value of x in reactant side you get product .
-3+13×12/13=9
Answer:
x = 12/13
Step-by-step explanation:
-3 + 13x = 9
Adding 3 to both sides,
13x = 12
Dividing both sides by 13,
x = 12/13
We can prove it by putting the value of x we got in the given equation:
LHS = -3 + 13x
= -3 + 13 (12/13)
= -3 + 12
= 9 = RHS
Hence, proved.

B. two variables are measured and two groups are compared
C. one variable is measured and there is only one group of participants
D. two variables are measured and there is only one group of participants
Answer:
Option B, two variables are measured and two groups are compared
Step-by-step explanation:

A company produces two types of jackets; windbreakers and rainbreakers. The company has at most 61 hours of finishing time per week and 67 hours of packaging time per week. Each windbreaker jacket takes 59 minutes of finishing time and 21 minutes of packaging time per week, whereas each rainbreaker jacket takes 58 minutes of finishing time and 34 minutes of packaging time per week. The company's profit for each windbreaker and rainbreaker jacket is 28 and 41, respectively. Let x denote the number of windbreaker jackets they should produce and y denote the number of rainbreaker jackets they should produce. The company wants to maximize profit. Set up the Linear Programming Problem for this situation.
Answer:
Max p = 28x + 41y
Subject to
59x + 58y ≤ 3660
21x + 34y ≤ 4020
x ≥ 0, y ≥ 0
Step-by-step explanation:
As given ,
Windbreakers Rain breakers Total
Finishing time 59 min 58 min 61 hr
Packaging time 21 min 34 min 68 hr
Profit 28 41
Let
The number of windbreaker jackets they should produce = x
The number of rain breaker jackets they should produce = y
As given,
The company wants to maximize profit.
⇒ Maximum Profit , p = 28x + 41 y
Now,
As 1 hour = 60 min
⇒61 hours = 61×60 = 3660 min
and 67 hours = 67×60 = 4020 min
∴ we get
The equations become
59x + 58y ≤ 3660
21x + 34y ≤ 4020
x ≥ 0, y ≥ 0
So, the Linear Programming Problem (LPP) for this problem is -
Max p = 28x + 41y
Subject to
59x + 58y ≤ 3660
21x + 34y ≤ 4020
x ≥ 0, y ≥ 0

pls help I need help ALL I NEED IS THE WORK PLSSSS HELP
Answer:
1. Y = -4/3
2. 2x = 2y + 10
Step-by-step explanation:
1. y =− 2y − 4
Step 1: Add 2y to both sides.
y + 2y = −2y − 4 + 2y
3y = −4
Step 2: Divide both sides by 3.
3y/3 = -4/3
y = -4/3
2. solve for x
y=1/2x-5
Step 1: Flip the equation.
1/2x−5=y
Step 2: Add 5 to both sides.
1/2x−5+5=y+5
1/2x=y+5
Step 3: Divide both sides by 1/2.
1/2x/1/2=y+5/1/2
x=2y+10
