Answers

X=1, Y=-2. Heres your answer. It should be C

Answer:

(1, -2)

Step-by-step explanation:

So we can work straight away

The elimination method deals with eliminating one variable so that you can find the other, then substituting that back in to find the one we eliminated originally. So, let's add our two equations together:

    9x - 3y = 15

+  3x + 3y = -3

   12x         = 12

So now that we've reached a new equation, 12x = 12, we can divide both sides by 12 and get that:

x = 1

Substituting this back into the second equation (though you could sub it into either one):

3(1) + 3y = -3

3 + 3y = -3

3y = -6

y = -2

Therefore, x = 1 and y = -2, also represented as (1, -2)

Hope this helps!

If p(x) = 2x2 – 4x and q(x) = x – 3, what is (p circle q) (x)?
2x2 – 4x + 12
2x2 – 16x + 18
2x2 – 16x + 30
2x2 – 16x + 15

Answers

Answer:

2x^2 - 16x + 30

Step-by-step explanation:

Here, we want to get the composite function;

p•q(x)

All we have to do here is to replace the x value in p(x) by the totality of q(x)

we have this as ;

= 2(x-3)^2 - 4(x-3)

= 2(x^2 -6x + 9) - 4(x-3)

= 2x^2 -12x + 18 -4x + 12

= 2x^2 - 16x + 30

(1-sin^ 2 theta)(tan theta)=?

Answers

Answer:

sin 2theta/2

Step-by-step explanation:

(1-sin^ 2 theta)(tan theta)

Recall in trig identity that

sin^2 theta + cos^2 theta = 1

cos^2 theta = 1-sin^ 2 theta

Also tan theta = sin theta/cos theta

Substitute

(1-sin^ 2 theta)(tan theta)

=cos^2 theta *  sin theta/cos theta

= costheta sin theta

Since sin2 theta = 2sintheta cos theta

sintheta cos theta = sin 2theta/2

If 55 Canadian Dollar = 157 Qatari Riyal and 1 Qatari
Riyal = 30NC, how much Canadian Dollar is equal to Rs.2870?​

Answers

Answer:

5cd=157qr

1cd=157/55qr

or

qr=55/157cd

Step-by-step explanation:

1qr=30nc

55/157×cd=30nc

55/157×1/30×cd=1nc

1nc=0.011670cd

rs2870=0.01167×2870cd=33.49cd

₹2870 is equal to 33.49 CD.

Given that, 55 Canadian Dollars=157 Qatari Riyal and 1 Qatari Riyal=30NC.

We need to find how much the Canadian Dollar is equal to ₹2870.

How to convert Canadian dollars to rupees?

The Canadian dollar is the currency of Canada. It is abbreviated with the dollar sign $, or sometimes CA$, Can$ or C$ to distinguish it from other dollar-denominated currencies. It is divided into 100 cents.

Converting the Canadian Dollar to rupees use 1 NC=0.011670 CD.

1 QR=30 NC

55/157 CD=30 NC

55/157×1/30×CD=1 NC

1 NC=0.011670CD

₹2870=0.01167×2870 CD=33.49 CD

Therefore, ₹2870 is equal to 33.49 CD.

A pet store sells cats for $50 and dogs for $100. In only one day it sells a total of 4 pets and makes $300, find out how many cats and dogs it sold by writing as a system of equations and graphing to solve it.​

Answers

Answer:

$1,350

Step-by-step explanation:

. $50 = Cats

. $100 = Dogs

. Total of pets = 4

. $300 for 4 pets
