10/d(d-2) + 4/d = 5/d-2

Mathematics

1 answer:

ANEK [815]3 years ago

5 0

Answer:

impossible

Step-by-step explanation:

a denominator can’t be equal to 0. So:

d ≠ 0 ; d ≠ 2

(10 + 4d - 8)/d(d-2) = 5d/ d(d-2)

4d + 2 = 5d

d = 2

But we have said that d can’t be equal to 2, so the equation is impossible.

I need help with this problem, i am confused and don't know what to do.

klasskru [66]

Problems a through c are asking you what the values would be at those values.

What will the value of $f(x)$ be at $x=0$ ? Let's look at the graph.

It seems at $x=0$ , $f(x)=0$ , meaning that $f(0)=0$

Let's do the same for the others.

At $x=-3$ , $f(-3)=2$

At $x=2$ , $f(2)=-4$

For the last question, it is giving us the $f(x)$ value and asking us which $x$ values would give us that.

At $f(x)=3$ , $x=-2$ .

*Note* this function is continuous to the right, meaning that there is another point where $f(x)=3$ .

Hope this helps.

頑張って!

Estimate 4704 - 1193 by first rounding each number to the nearest hundred.

sveticcg [70]

Answer:

$3500$

Step-by-step explanation:

Given the following question:

$4704-1193$

To estimate we to the nearest hundred we have to look at the number next to the hundreds place value to determine if it's greater than five.

$4704$

$0 < 5 = 4700$

$1193$

$9 > 5 = 1200$

$4700 - 1200$

$4700 -1200=3500$

$=3500$

Hope this helps.

Hello can you please help me posted picture of question

White raven [17]

Correct answer will be option A.

Two events are independent if the occurring of one event does not impact the occurring of the other event.

So this means, the knowledge of one event is having no impact on the probability of occurrence of the second event. Thus option A is correct
