If f has a local maximum value at x = a, what would you expect the graph of f ' to look like near x = a?

1 answer:

5 0

You would expect $f$ to be increasing to the left of $x=a$ , and decreasing to the right, which corresponds to $f'$ being positive when $x$ (but near $x=a$ ) and negative when $x>a$ .

Answer:

(12, 48 )

Step-by-step explanation:

Given the 2 equations

y = 5x - 12 → (1)

y = 3x + 12 → (2)

Substitute y = 5x - 12 into (2)

5x - 12 = 3x + 12 ( subtract 3x from both sides )

2x - 12 = 12 ( add 12 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Substitute x = 12 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 3(12) + 12 = 36 + 12 = 48

solution is (12, 48 )

Need the answer to this

ki77a [65]

Answer:

$\frac{2}{(x + 3)}$

Step-by-step explanation:

$\frac{2x - 10}{x^{2} - 2x - 15}$

pull 2 from top

$\frac{2(x - 5)}{x^{2} - 2x - 15}$

we are looking to cancel (x-5) so will start with

(x - 5)(x + 3), selected (x+3) because the sign must be negative and must multiply to -15

$\frac{2(x - 5)}{(x - 5)(x + 3)}$

now cancel (x-5)

$\frac{2}{(x + 3)}$

If f(x) = 4^x - 8 and g(x) = 5x + 6, find (f - g)(x)

olganol [36]

Answer:

$4^x-5x-14$

Step-by-step explanation:

$f-g=(4^x-8)-(5x+6)=4^x-8-5x-6=4^x-5x-14$

Answer:

x = 18

y = 54

Step-by-step explanation:

A straight line equals 180 degrees.

Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.

Because there is a right angle, we can subtract 90 -72 = 18.

18 + 2x = 3x

18 = x

A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.

2 tenths and 4 hundreds is written .24

.42 is greater than .24

.42 > .24

Hope this helps.
