First, to make the equation easier to read, you want to add the x’s together. you should then get 2.6x-3.8=-9. then, you want to add the 3.8 to both sides, to make the x stand alone. you should end up with 2.6x=-5.2. to find x, you then want to divide both sides by 2.6. your final answer after dividing should be x=-2
Factored form: (-x-4) (x-6)
Standard form: y= −x^2 + 2x + 24
Zeros: -4, 6
Use the inverse sine function on a calculator.
arcsin (0.88) = 1.08 radians
PICTURE1: They are both 45
PICTURE2: 810
I'll give you a pdf so you can see it yourself and the correct answer is -32b - 32b
