Answer:
x^2-1
Step-by-step explanation:
KX = x+4 so solve for k.
Divide both sides of the equation by x and you get K=4.
Plug it in, and you get (4)(7)=28
Your answer is 28.
Step-by-step explanation:
y = 0.5x + 4
When y = 2, x = -4. (shown in graph)
When y = 6, x = 4. (shown in graph)
Hence the domain would be -4 <= x <= 4.
Answer:
2 square root of 20
3*5^1/2+5^1/2
4* 5^1/2
Step-by-step explanation:
Answer:
Step-by-step explanation:
2*(3x + 4 + 2x) + 2*(5x + x +4) = 2 *(5x +4) + 2*(6x +4 )
= 2*5x + 2*4 +2*6x + 2*4
=10x + 8 + 12x + 8
=22x + 16
