Answer:

D. (17,-1)

Step-by-step explanation:

We'll start by canceling out x. To do so, multiple the first equation by -1

-1( x - 2y)=( 19 )(-1)

This gives us:

-x +2y = -19

x + 3y = 14

Add the equations together:

→ 5y = -15

→ y = -1

Plug in y = -1 into an equation:

→ x + 3(-1) = 14

→ x - 3 = 14

→ x = 17

(17,-1)

Hope this helps!

How are the two angles the same?
tino4ka555 [31]

Answer:

if ABCD is a rhombus then the diagonal of rhombus bisect it into two equal triangles.

Step-by-step explanation:

In triangles ABC and CDA,

  1. AB= CD (S) because rhombus has equal sides.
  2. BC = AD (S) as as reason 1.
  3. AC= AC (S) being common side of both triangles

so the triangles are congruent to each other by S.S.S. fact/ axiom

Question 8 of 10
Sliva [168]

Answer:

y = (-3/7)x + 2

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

all you need to do is plug the values into the equation! :)

since your slope is (-3/7), plug that in for m.

y = mx + b ⇒ y = (-3/7)x + b

and since your y-intercept is 2, plug that in for b.

y = (-3/7)x + b ⇒ y = (-3/7)x + 2

therefore, the line's equation in slope-intercept form is y = (-3/7)x + 2.

<em>don't worry about the parentheses, i only put them in there to separate the 7 in -3/7 from x. i'm not good at putting equations in here on brainly lol i just wanted to make sure you didn't think that it was -3 over 7x.</em>

<em />

i hope this helps! have a lovely day <3
