Answer:

C

Step-by-step explanation:

x + y = 2

Subtract x from both sides;

y = -x + 2

3x - 4y = 27

Substitute y;

3x - 4(-x + 2) = 27

Distribute;

3x + 4x - 8 = 27

7x - 8 = 27

Add 8 to both sides;

7x = 35

Divide both sides by 7;

x = 5

C is the point (-301, 601)<br> Does C lie on the straight line passing through A and B?
Marat540 [252]

Answer:

There is no picture or graph to go with the question so I am afraid I will not be able to give you a specific answer.

To find out if a point (x, y) is on the graph of a line, we plug in the values into that equation and see if we get a true statement, such as 10 = 10. If we get something different, like 6 = 4, we know that the point is not on the line because it does not satisfy the equation. Plug in (-301, 601) into the equation of the line to see whether that point lies on it or not.

Step-by-step explanation:

Suppose the equation of the straight line that passes through E and F is this:

y = 7x + 2

We are to figure out whether or not the point (1, 10) lies on that line. In order to do this we would plug in (1, 10) into the equation, with 1 being x and 10 being y.

10 = 7(1) + 2 = 7 + 2 = 9

10 = 9 is a false statement. Therefore, the point (1, 10) does NOT lie on the line y = 7x + 2.

If you were to provide an image or graph that shows the equation of line AB then perhaps I would be able to answer your question with a specific answer.

LOL 3 more to gooo . find the value of x
garri49 [273]

Answer:

17

Step-by-step explanation:

These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.

What is the value of r of the geometric series n=11.3(0.8)n-1
jeyben [28]

the value of r of the geometric series n=11.3(0.8)n-1

an=11.3(0.8)^{n-1}

General formula for nth term of any geometric series is   a_n=a_1(r)^{n-1}

Here 'r' is the common ratio

a_1 is the first term of the series

Now we compare the given formula with general formula

Compare  an=11.3(0.8)^{n-1}  with  a_n=a_1(r)^{n-1}

The value of r= 0.8

What is <br> Sin A?<br> Cos A?<br> Tan A?
Katyanochek1 [597]

Answer:

See explanation

Step-by-step explanation:

\sin A =  \frac{12}{20}  =  \frac{3}{5}  \\  \\  \cos A =  \frac{16}{20}  =  \frac{4}{5}   \\  \\ \tan A =  \frac{12}{16}  =  \frac{3}{4}

Answer:

A (i) impossible, because the card D doesn't exist.

(ii) evens, because the number of vowel cards and consonant cards is equal  

B (i)  62 - 24 - 13 - 16 = 9

(ii) 24/62*100% = 38.7%

(iii) (13+16) / 62 * 100% = 46.77%
