3 sin x + 5 cos x = 0
3 sin x = - 5 cos x /: cos x ( divide both sides by cos x )
3 sin x / cos x = - 5
3 tan x = - 5
tan x = -5/3
x = arc tan (-5/3)
x ≈ - 59.036°
12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.
13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1
14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.
16. the equation 6 (x+2)= 5 (x+7) has only one solution. it is x=3.
sorry i wasn't able to answer the other 3,

Answer:
6.3 to the nearest 10th
Step-by-step explanation:
Hope this helped :)
Answer:
The first answer.
Step-by-step explanation:
First of all, the circle on -3 did not have filling so that means it is not equal to z. Then we look on the circle on 6. It does have a filling which means it is equal to and greater than z. Now we look in between -3 and 6. Is there any white spots? If no, then we don’t have to use an OR. Therefore, the first answer is the only plausible answer.
Answer:
A.1
Step-by-step explanation:
-x+8>6
Subtract 8 from each side
-x+8-8>6-8
-x > -2
Divide by -1. Remember that flips the inequality
-x/-1 < -2/-1
x<2
The only number that is less than 2 is one so
