Answer:
D. -8x-54
Step-by-step explanation:
Apply the distributive property.
6-4(3(2x)+3*5-4x)
Multiply 2 by 3
6-4(6x+15-4x)
Multiply 3 by 5
6-4(6x+15-4x)
Subtract 4x from 6x
6-4(2x+15)
Apply the distributive property.
6-4(2x)-4*15
Multiply 2 by -4
6-8x-4*15
Mutliply -4 by 15 6-8x-60
Subtract 60 from 6
Answer:
The absolute value of 12, is 12...
Step-by-step explanation:
Answer:
This is how tackle this type of problem:
Draw a right triangle with the indicated sides: side opposite the angle = 12 and hypotenuse = 13
Then, calculate the 3rd side by Pythagoras: x2 + 122 = 132
x2 = 169 - 144
x2 = 25
x = 5
Now, we have all 3 sides of our diagram triangle, so we can find all the trig ratios for the angle.
Next, we use the double angle formula to simplify cos(x + 30) = cos x cos 30 - sin x sin 30
= 5/13 . √3/2 - 12/13 . 1/2
= 5√3 /26 - 6/13
= (5√3 - 12) / 26

please mark me as brainlist please hi
If the variables disappear and you get a statement that is never true,such as 0=5 or 4=7 then there is no solution meaning when graphed the two equations will form parallel lines which never interact
Answer:
7
Step-by-step explanation:
From the graph....you can see g(-2) = -3 ( see attached diagram below)
then f(-3) = 7 ( because -3 is less than -2. ... so it = 7)
