The hypotenuse MO is found from the Pythagorean theorem to be
MO = √(12² + 5²) = √(144+25) = √169 = 13
The sine of angle O is the ratio of the opposite side (MN=12) to the hypotenuse (MO=13). The appropriate choice is ...
C. 12/13
Answer:
Step-by-step explanation: -9,2,-7,-3,-35, and -6
2x+2 would be the expression
Xavier wants to earn more then 575 dollars a week, he will have to sale x<3,600 a week . So the answer is C
So we need to solve:
3ˣ⁻¹ = 9ˣ⁺²
To do this, we need to have the same base for both sides of the equation.
So let's go with the base of 3.
3² = 9
3ˣ⁻¹ = (3²)ˣ⁺²
3ˣ⁻¹ = 3²ˣ⁺⁴
Since the bases are the same now, we need to get rid of them and we would get:
x - 1 = 2x + 4
Subtract both sides by 2x:
-x - 1 = 4
Add 1 to both sides:
-x = 5
Divide both sides by -1:
x = -5
