System of eqns
<span>
2x + y = −4 and

y = 3x + 2

substituting second eqn into 1st

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

2x + 3x = -4 - 2

5x = -6

x = -6/5

y = 3*(-6/5) + 2 = (-3*6 + 2*5)/5 = (-18 + 10)/5

= -8/5

</span><span>negative 6 over five comma negative 8 over 5 </span>

2x+3x+2=-4(cause y=3x+2)
5x=-6
x=-6/5
f(-6/5)=-8/5
negative 6 over 5

To the nearest tenth, find the perimeter of ∆ABC with vertices A(-1,4), B(-2,1) and C(2,1).

First we need to find the length of each side of the triangle , and for that we need to use the distance formula, that is
$d =\sqrt{(x_{2} -x_{1})^2 +(y_{2} -y_{1})^2}$
$AB = \sqrt{(1-4)^2 +(-2+1)^2}= \sqrt{10}$
$\sqrt{BC} = \sqrt{(1-1)^2 + (2+2)^2}=4$
Perimeter is the sum of all sides.
$Perimeter = AB + BC + AC = \sqrt{10}+4 +\sqrt{18}$
$Perimeter= 11.4$

How to graph 200-25x=y

In-s [12.5K]

Simplifying
y = -25x + 200

Reorder the terms:
y = 200 + -25x

Solving
y = 200 + -25x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 200 + -25x
