For this case we have the following system of two equations with two unknowns:

-2x + y + 6 = 0\\2x + y-8 = 0

Adding both equations we have to eliminate the variable "x":

y + y + 6-8 = 0

Adding common terms, keeping in mind that different signs are subtracted and the sign of the major is placed:

2y-2 = 0\\2y = 2

Answer:

2y = 2

Option A

Multiply and Simplify <br><br> cos(theta) sin(theta)(sec (theta) + csc (theta))
fredd [130]

Before I put out my answer, I just want make note that sec() = 1 / cos() and csc () = 1 / sin ()

1) Once you distribute cos()sin() to sec(), the cos() will cancel out with the sec() to make it just sin(), and once cos()sin() is distributed to csc(), the sin() will cancel out with the cos()

2) After doing that you should just be left with sin() + cos()

3) And since no more simplification can be done, that is your answer :D

Please help I would love it if you do (math)

This question is basically asking you what number was this originally until we timesed it by 100. For the first column take away two zeros or for answers like 560 and 4830 imagine there is a decimal point at the end and move it two spaces forward so it would now be 5.6 and 48.3

For the second column add two zeros at the end instead.

For the questions at the bottom basically for all the questions except the bottom one how many numbers follow the first number.

For example.

96,629 = 1
100

Because three numbers follow the first 6.

Hope this makes sense because I don’t know if it does.
