I'll help you with this so reflections is not hard.
For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).
For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).
sign is basically + or - if need to know.
I hope this helps you in the long run.

Step-by-step explanation:
The solution of the equation:
x = -0.28 to the nearest tenth.
x = 4.53 to the nearest tenth.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
A quadratic equation,
4x²-27x-5 = -10x
Simplifying,
4x²-27x-5 + 10x = 0
4x²-17x-5 = 0
So,
x = {-(-17) ± √(289 + 80)}/8
x = (17 ± √369) / 8
When we take - sign,
x = - 0.276
x = -0.28 to the nearest tenth.
When we take + sign,
x = 4.526
x = 4.53 to the nearest tenth.
Therefore, the values are x = -0.28 and x = 4.53.

A study found that the average time a person spent exercising each week was 84 minutes, but there could be up to a 3% error in this
number. Which of these could be the actual average time spent?
es
A)
78.32 minutes
B)
81.48 minutes
C)
87.32 minutes
D)
88.64 minutes
B is the answer
Answers
Answer:
C
Step-by-step explanation:
The actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes
What is percent error?"percent error = [(estimated value - actual value) / (actual value)] × 100"
For given example,
percent error (e) = 3%
estimated average time spent (x) = 84 minutes
We need to find the actual average time spent (y)
Using the formula of percent error,
⇒ e = [(x - y)/y] × 100
⇒ 3 = (84 - y)/y × 100
⇒ (84 - y)/y = 3/100
⇒ (84 - y) / y = 0.03
⇒ 84 - y = 0.03y
⇒ 84 = 0.03y + y
⇒ 84 = (1.03)y
⇒ y = 81.5 minutes
Therefore, the actual average time = 81.5 minutes
The correct answer is an option (B) 81.48 minutes

Can 10, 11, 2 be measures of the sides of a triangle
Answers
Answer:
Yes
Step-by-step explanation:
The Triangle Inequality Theorem says the sum of any two side lengths of a triangle has to be greater than the third side.
With the measures of 10, 11, and 2, this follows the theorem.
For example, 10 + 11 is 21, which is greater than 2.
11 + 2 is 13, which is greater than 10.
This works for all the combinations, so 10, 11, and 2 can be the side lengths.
