Answer:
6x-8
Step-by-step explanation:
to simplify you must distribute the parenthesis
so...
8x-16 -2x+8
now combine like terms
so..
8x-2x and 8-16
6x-8 is your final answer
hope this helps
Answer:
7x^3-7x^2+14x
Step-by-step explanation: hope I helped
Answer:
<XYZ = 117°
<XYW+ WYZ = 117°
(6x+44)+(-10x+65)= 117°
6x+44-10x+65= 117°
-4x+ 109= 117°
-4x= 117-109
-4x= 8
x= 8/-4
x= -2
<XYW= 6x+44= 6×-2+44= -12+44= 32°
<WYZ= -10x+65 = -10×-2+ 65= 20+65= 85°
Step-by-step explanation:
x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
Step-by-step explanation:
- Direct variations are ALWAYS linear and ALWAYS go through the origin.
Because y = kx is linear function and y = 0 when x = 0
- Inverse variations are NEVER linear and NEVER go through the origin.
Because y = k/x is not a linear function and x is never zero as we can't divide by zero.
