Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = 
and tan x = 
thus
+ tanΘ × cosΘ
= 
+ 
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
X+2.6=1.7
x+12=7
x+12-12=7-12 (subtract 12 from both sides)
x=-5
Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
Answer:
Slope is 5.
Step-by-step explanation:
y + 3x = 8x -7
y = 5x - 7
coefficient in front of x is the slope/rate of change once you get the equation slope intercept for y = mx + b. m is the slope.
