Yo sup??
y=(x+4)(x-2)
to find the x intercept put y=0
0=(x+4)(x-2)
so either x=-4 or x=2
Therefore the graph intersects the x axis at -4 and 2
Lenght of x intercept=|-4-2|=6 units
y=(x+4)(x-2)
=x^2+2x-8
This is an upward opening parabola
To find the coordinates of the vertex we can apply the formula
(-b/2a,-D/4a)
b=2
a=1
D=b^2-4ac
=4-4*1*(-8)
=4+32=36
Vertex=(-2/2*1,-36/4*1)
=(-1,-9)
Hope this helps.
That would be 40%
Explanation:
2 divided by 5= 0.4
Move the decimal to the right twice is 40%
(2x + 10) + (6x + 1) = 180 - 79
Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that 
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is 
) and apply it to each side
We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1
