Answer:

$\large \boxed{\sf A) \ 12}$

Step-by-step explanation:

How do i find the solution to x+y= -2 y=x+2

olga2289 [7]

Answer:

x = -2 and y = 0

Explanation:

You just put the value of one variable in terms of the other in one of the two equations. Then, solve it and BOOM you'll have your solution.

x + y = -2 ........... (a)

y = x + 2 ............ (b)

Put (b) in (a),

x + (x + 2) = -2

2x = -4 => x = -2

Put x = -2 in (b),

y = x + 2 = -2+2 = 0

Thus, x=-2 and y=0

Answer:

Distance is 6.7units to the nearest tenth.

Explanation:

To solve this problem, we the distance formula. And this is given as:

$D = \frac{|a x + b y + c|}{\sqrt{a^2 + b^2}}$

We were given the equation:

y = 2 x + 4

This can also be rewritten as:

y – 2 x – 4 = 0.

Therefore, a = -2, b = 1 and c = -4

Also, we were given the points:

(x, y) = (–4, 11)

Making use of the above formula for distance, we have:

$D = \frac{|-2\times -4 + 1\times 11 + -4|}{\sqrt{-2^2 + -4^2}}$

$D = \frac{15}{\sqrt{5}}$

D = 6.7units (to the nearest tenth)
