Step-by-step explanation:

The graphed function has its local maximum at x = - 1 and local minimum at x = 2.

The function is decreasing between those points and increasing outside.

The increasing intervals are

x ∈ (- ∞, - 1) ∪ (2, + ∞)

What is the center of MN given M(3, -1) and N(7,-5)

Neko [114]

Answer:

(5, -3)

Step-by-step explanation:

So the center of the two points, or a line can be defined using the equation: $midpoint=(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})$ . So using the two points you gave, you simply plug the values in to get

$midpoint=(\frac{3+7}{2}, \frac{-1+(-5)}{2})\\$

Add numerators:

$midpoint=(\frac{10}{2}, \frac{-6}{2})$

Simplify fraction:

$midpoint=(5, -3)$

Help me I forgot everything from last year

irakobra [83]

Answer:

17/24

Step-by-step explanation:

With unlike denominators find the Least Common Denominator (LCD)

LCD = 24

Multiplying numerators and denominators to get the LCD in all fraction denominators

= 2×4/6×4 + 3×3/8×3

Then rewriting the equation with the equivalent fractions

= 8/24 + 9/24

With like denominators we can operate on just the numerators

= 8/24 + 9/24

= 17/24

A company has two large computers. The slower computer can send all the company's email in 60 minutes. The faster computer can c

Lelu [443]

Answer:

If both computers are working together, it will take 24 minutes to do the job

Step-by-step explanation:

It is given that,

There are two computers.The slower computer can send all the company's email in 60 minutes.

The faster computer can complete the same job in 40 minutes

To find the LCM of 40 and 60

LCM (40, 60) = 120

To find efficiency of 2 computers

Let x be the efficiency of faster computer and y be the efficiency of faster computer

x = 120/40 = 3

y = 120/60 = 2

then, x + y = 3 + 2 = 5

Therefore efficiency of both the computer work together = x + y =5

To find the time taken to work both the computer together

time = 120/5 = 24 minutes
