Substitute -2 for x

$f( - 2) = 2( - 2) + 3 \\ y = - 4 + 3 \\ y = - 1$

Hope it helps

Answer:

-1

Step-by-step explanation:

Hi student! Let me help you out on this question.

_____________________

To find the value of f(-2), we need to stick in -2 for x.

$\mathsf{f(-2)=2\cdot(-2)+3}$ . Multiply first.

$\mathrm{f(-2)=-4+3}$ . Now simplify completely.

$\mathsf{f(-2)=-1}$ . Which is our final answer.

Hope that this helped you out! have a good day ahead.

Best Wishes!

The slope of the line 3x - y = 4 between x = 3 and x = 6 is 3. What is t he slope between the interval x = 12 and x = 15?

Allushta [10]

The slope of the line does not change regardless of value of x. therefore slope is still 3.

While hiding behind a bush, Chamara sees an ice cream truck and yelps in joy. Kevin, Justin, and Jason come running over to buy

max2010maxim [7]

So all four went to the ice-cream lady and got first 2 ice-creams, the lady said, "ok 4 bucks for the first one, and half-off the second, or 2 bucks".

so, for the first two cones, they didn't pay 4+4 bucks, they only paid 4+2 bucks, and for the next two cones, they paid the same.

so in total for the four cones they paid 4+2 and 4+2, or 12 bucks.

how many times do 4(boys) go into 12(total)? 12/4.

Haroldo, Xerxes, Regina, Shaindel, Murray, Norah, Stav, Zeke, Cam, and Georgia are invited to a dinner party. They arrive in a r

alexira [117]

Answer: The probability is P = 0.056

Step-by-step explanation:

The invited ones are:

Haroldo, Xerxes, Regina, Shaindel, Murray, Norah, Stav, Zeke, Cam, and Georgia

So we have a total of 10 persons.

The case where Xerxes arrives first and Regina arrives last is:

We have 10 slots, each slot corresponds to who arrived in which time.

For the first slot we have only one option, this is Xeres.

For the next slot we have 8 options (because Xeres already arrived, and Regina must arrive at last)

For the next slot we have 7 options.

for the next one we have 6 options, and so on.

So the combinations are:

C = 1*8*7*6*5*4*3*2*1*1 = 40320

Now, the total number of combinations is:

for the first slot we have 10 options, for the second we have 9 options and so on.

c = 10*9*8*7*6*5*4*3*2*1 = 725760

The probability is the combinations where Xerxes arrives first and Regina rrives last divided the total number of probabilities.

P = C/c = 0.056
