Answer:
D. -2x - 8
Step-by-step explanation:
1) Simplify 1/3(6x+15) to 6x+15/3
-6x+15/3 - 3
2) Factor out the common term 3.
-3(2x+5)/3 - 3
3) Cancel 3.
-(2x+5)-3
4) Remove parentheses.
-2x-5-3
5) Collect like terms.
-2x+(-5-3)
6) Simplify
-2x-8
W - 6/5 = -2
w - 6 = -2 x 5 = -10
w = -10 + 6
w = -4
Answer:
C) Having a driver's license, and having blue eyes.
Explanation:
These are two completely separate variables whereas for the other options, there is a clear correlation between them.
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
Answer:
$41.39
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 44.99 × 8/100
Discount = 44.99 x 0.08
