Answer:
Step-by-step explanation:
The first thing that you can do is to factor out an x^2 from the expression.
x^2(2x^2+4x-30)
The next step is to factor out a 2.
2x^2(x^2+2x-15)
Finally, you can factor the quadratic inside.
2x^2(x-3)(x+5)
And now you're finished! Hope this helps!
Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached.
Slope is the change in coordinate of the y coordinate to the x coordinate.
Mathematically, slope m = ∆y/∆x
From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)
m = ∆y/∆x = 3/1
∆y/∆x = 3/1
y/x = 3/1
Cross multiply
y × 1 = 3 × x
y = 3x
Hence the slope of the line is y = 3x
