2 - 6 ( -5t + 1 )

Distribute the 6 to the numbers inside the parenthesis (PEMDAS)

2 - 6*- 5t - 6*1

= 2 + 30t - 6

= 30t - 4

Option C is correct.

2 - 6 ( -5t + 1 )

Apply distributive property first:

2 - 6*-5t -6*1

Simplify:

2+30t -6

Combine like terms:

30t - 4

The answer is C.

(f•g)(2)=27, the distance in miles the bicycle traveled

Option D is correct.

Step-by-step explanation:

Rate of a bicycle traveling in miles per hour : $f(x)=2x^2+1$

the time the bicycle traveled in hours: $g(x)= x+1$

We need to find (f.g)(2)

Solving:

$(f.g)(2)=(2(2)^2+1)(2+1)\\(f.g)(2)=(2(4)+1)(3)\\(f.g)(2)=(8+1)(3)\\(f.g)(2)=9*3\\(f.g)(2)=27$

So, (f•g)(2)=27, the distance in miles the bicycle traveled

Option D is correct.

1) -5-6 = -11
2) 35 -(-8) is the same as 35+8=43
3) since they have the same denominators you can do 2-3 = -1 and then add the denominator after, it equals -1/5
4) -3 1/8

Answer:

D -24/25

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

cos(x) = ⅘

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25
