Answer:

-9/2

Step-by-step explanation:

-9 is the same as -9/1

if we multiply -9/1 and 1/2 we multiply the numerators to get -9 and multiply denominators to get 2 or -9/2

Use the equation m Subscript PQ Baseline equals StartFraction f left parenthesis x 1 plus h right parenthesis minus f left paren

babunello [35]

Answer:

m = 12

Step-by-step explanation:

For f(x) = 2x² you want to find the slope m using ...

m = (f(x+h) -f(x))/h

at x=3.

Filling in the function definition and its arguments, we have ...

m = (2(x+h)² -2x²)/h = (2x² +4hx +2h² -2x²)/h = 4x +2h

The value of this as h goes to zero is ...

m = 4x

At x=3, the slope is ...

m = 4·3 = 12

_____

The attached graph shows a numerical estimate of the slope (f'(3)=12) and the line with that slope through the point P(3, 18). The line certainly appears to be tangent to the curve at that point.

Let line $l_1$ be the graph of $3x + 4y = -14$. Line $l_2$ is perpendicular to line $l_1$ and passes through the point $(-5,7)$.

Vinil7 [7]

$3x+4y=-14\implies y=-\dfrac{3x+14}4$

and so $\ell_1$ has slope -3/4. Then any line perpendicular to $\ell_1$ has slope 4/3.

Given that $\ell_2\perp\ell_1$ and $\ell_2$ passes through (-5, 7), its equation is

$y-7=\dfrac43(x+5)\implies y=\dfrac{4x}3+\dfrac{41}3$

so that $m=\frac43$ and $b=\frac{41}3$ , which gives

$m+b=\dfrac{45}3=\boxed{15}$
