The value of the y-intercept of the line y = -3x - 2 is the negative 2. Then the correct option is B.

<h3>What is the equation of line?</h3>

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The equation of the line is given below.

f(x) = -3x - 2

On comparing, we have

m = -3 and c = -2

Then the value of the y-intercept of the given line is the negative 2.

Then the correct option is B.

Answer:

  C.  1

Step-by-step explanation:

You are asked for the y-intercept of the piecewise-defined function f(x). That will be the value of f(0).

__

<h3>function definition</h3>

We assume you intend the function definition to be ...

  f(x)=\begin{cases}-3x-2&\text{for }-\infty < x < -2\\-x+1&\text{for }-2\le x < 3\\2x+5&\text{for }3\le x < \infty\end{cases}

<h3>y-intercept</h3>

The first step in evaluating a piecewise-defined function is to identify the applicable domain and corresponding function definition. The value x=0 is included in the domain -2 ≤ x < 3, so the second part of the function applies.

  f(0) = -0 +1 = 1

The y-intercept of function f is 1.

_____

Attached is a graph of the function showing its y-intercept.

A stadium has 50 comma 00050,000 seats. Seats sell for ​$3030 in Section​ A, ​$2424 in Section​ B, and ​$1818 in Section C. The
Mariulka [41]

A= B+C

As given, A+B+C = 50000 seats

A+(B+C) = 50000

2A = 50000

A= 25000 seats

Now section A sells seats at $30 each

So, 25000\times30=750000

Now, B+C = 25000

B = 25000-C

B sells at $24 and C sells at $18

So, 24B+18C = 538800

Now as section A incurs an amount of $750000 from booking, so B and C will incur 1288800-750000 = 538800 where $1288800 is the total booking amount.

24B+18C = 538800

24(25000-C)+18C=538800

600000-24C+18C=538800

6C = 61200

C = 10200

Now, B = 25000-C

B = 25000 - 10200 = 14800

Hence, section A has 25000 seats

Section B has 14800 seats

Section C has 10200 seats

Answer: y = 25

Explanation:

2x+5 = 3x - 33

x = 38

2x+5 + 4y-1 = 180

2(38) + 5 + 4y - 1 = 180

y = 25

I hope this helped!

the cost of a mobile is set Rs.18000.If mrs.Sharma purchased it with 13% VAT. how much did she pay for it.​
Klio2033 [76]

Answer:

Rs.20340

Step-by-step explanation:

Cost of the mobile(without VAT) = Rs. 18000

VAT= 13%*18000

=13/100*18000

=13*180

= Rs.2340

Hence, Cost of the mobile phone with VAT= Rs.18000+ Rs. 2340

= Rs.20340
