b.
Answer:
Take a look at the sec 0 - tan 0 side
sec 0 is 1 / cos 0
tan 0 is sin 0 / cos 0 :
(1/ cos0) - (sin0 / cos0)
Subtraction of fractions with same denominators
= 1 - sin 0 / cos 0
Step-by-step explanation:
-4(8-3x)≥6x-8
Expand the left side.
-32+12x≥6x-8
Add 32 to both sides
12x≥6x+24
Subtract 6x.
6x≥24
Divide both sides by 6.
x≥4
Answer: x ≥ 4
Answer -1/12
Step-by-step explanation:
-7/12 + 1/2 cannot be added until you change 1/2 into 6/12.
To change 1/2 to 6/12, you have to multiply 1/2 by 6 because you want the same denominator. Since you can't just make a whole new fraction by changing the denominator, you have to multiply the numerator by 6 as well.
After changing the fraction, you should get -7/12 + 6/12.
now you can just add the numerators and denominators together and get -1/12!
