Answer:
6x -5 ≤ 2x
Step-by-step explanation:
Less than is a switch word so you put it after the product of 6 and a number, x. Since it is no more than 2x it could be less than or equal to 2x.
Answer:
steps
Step-by-step explanation:
1 / 1 - sinθ + 1 / 1 + sinθ = ((1 + sinθ) + (1 - sinθ)) / (1 - sinθ) x (1 + sinθ)
= 2 / (1 - sin²θ) = 2 / cos²θ
= 2 sec²θ
Answer:
17
Step-by-step explanation:
a[2]+b[2]=c[2]
8*8+15*15=hypotenuse.
64+225=289
hypotenuse=17
Answer:
(s*t)(-7) = 987
Step-by-step explanation:
s(x) = 2 - x²
t(x) = 3x
To find (s*t)(x), multiply s(x) and t(x).
(s*t)(x) = (2 - x²)(3x)
(s*t)(x) = 6x - 3x³
Now that you have (s*t)(x), plug -7 in.
(s*t)(-7) = 6(-7) - 3(-7)³
(s*t)(-7) = 6(-7) - 3(-343)
(s*t)(-7) = -42 + 1029
(s*t)(-7) = 987
