Answer:
18x² - 6x
Step-by-step explanation:
Differentiate using the product rule, that is
y = f(x)g(x), then
= f(x)g'(x) + g(x)f'(x)
here
f(x) = 3x² ⇒ f'(x) = 6x
g(x) = 2x - 1 ⇒ g'(x) = 2, thus
(3x²(2x - 1)
= 3x² × 2 + 6x(2x - 1)
= 6x² + 12x² - 6x
= 18x² - 6x
Answer:
207 m²
Step-by-step explanation:
width = x
length = 3x - 4
2(length + width ) = Perimeter
2(3x - 4 + x) = 64
4x - 4 = 64/2
4x - 4 = 32
4x = 32 + 4
4x = 36
x = 9 m - width
length = 3x - 4 = 3 · 9 - 4 = 23 m
Area = length · width = 23 · 9 = 207 m²
Answer:
The slope is 9, and the y-intercept is –2
Step-by-step explanation:
y = 9x - 2
y = 9x + (-2)
This is in the form of y = mx + c ,where m is slope and c is y-intercept.
So, The slope is 9, and the y-intercept is –2.
In y-intercept, intercept means to cut. So,
y-intercept means where the equation cuts the y-axis. We know that in y-axis, the value of x is 0. So, we put x = 0 in the equation to find y-intercept.
y = 9x + (-2)
y = 9×0 - 2
y = -2
Hence, y-intercept is -2.
