Answer:
4x-18y-18/12
Step-by-step explanation:
x/3 - 2(y+1)/4
1. Find the Least Common Multiple for the denominators (in this case it is 12)
4x/12 - 6(3y+3)/12
2. Use PEMDAS
4x/12 - 18y+18/12
3. Distribute the arithmetic sign
4x/12 + -18y-18/12
4. Combine the fractions
4x-18y-18/12
<span>sin(2x)= 2sin(x)cos(x)
can you finish the rest or need more help?
sin(6/5) should be the answer
so we have 2 sin(0.6)cos(0.6)
we know its sin (2x) identity
x=0.6
so its sin(2*0.6)</span>
Answer:
n = -4
Step-by-step explanation:
-32=8n
Divide each side by 8
-32/8 = 8n/8
-4 = n
y = x^2 + 5x -3
y-x =2
Replace y in the second equation with the first one:
x^2 + 5x -3 - x = 2
Simplify by combining like terms:
x^2 + 4x -3 = 2
Subtract 2 from both sides:
x^2 + 4x -5 = 0
Fctor the polynomial:
(x-1) (x+5) = 0
Solve for both X's:
x = 1 and x = -5
Now replace x in the second equation with both value and solve for y:
y -1 =2, y = 3
y - -5 =2, y +5 = 2, y = -3
Now combine the sets of answers:
(1,3) and (-5,-3)
Answer:
b(n) = 15 - 7(n - 1)
Step-by-step explanation:
15 is the y-intercept
-7 is the slope
