Well if youre tryna solve for x you mission would be to have x on one side and all other terms on the other
subtract 2y from both sides
3x = -2y+4
divide each side by 3
x = -2/3y+4/3

Algebra. I dislike Algebra, but well, I have to do it.

Mission #1: Get 2y on other side!!

Process: 3x+2y / 2y = 4 / 2y
               3x = 2 / y

Mission #2: Get x alone!!

Process: 3x / 3 = 2 / 3y
               x = 2 / 3y

MISSION COMPLETE!!

A triangular section of land is fenced off due to contamination. Two sides of the triangle are each 16 meters ( 16m) longer than
Sphinxa [80]

Answer: the shortest side is 30m

Step-by-step explanation:

Let the shortest side be a meters

If side 2 is 16m longer than the shortest side, then it is (16+a)meters.

The same goes with side 3.

Then,

a + (16+a) + (16+a) = 122m

32 + 3a = 122m

Collecting like terms together,

3a = 122 - 32

3a = 90

Divide by coefficient of a

3a/3 = 90/3

a = 30 meters

Check:

30 + (16+30) + (16+30)

30 + 46 + 46 = 112

Determine whether the following system of equations has one solution, no solution, or an infinite number of solutions. Explain y
expeople1 [14]
<span>A) 2x - 4y = 10
B) 7x - 9y = 12
Multiplying equation A by -3.5
A) -7x +14y = -35 then adding B
B) </span><span><span>7x - 9y = 12</span>
5y = -23
y = -4.6
</span>
2x -4*-4.6 = 10
2x + 18.4 = 10
2x = -8.4
x = -4.2
It has one solution (-4.2, -4.6)

One of Newton’s laws of motion states that objects in motion tend to stay in motion. What is the reason that this law may not al
Nastasia [14]

The answer is D.

The full specification of Newton's First Law is (from Wikipedia)

In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

On earth we're generally in slightly a non-inertial frame, with rotation and revolution around the sun. It's also impossible to turn of gravity, so objects are being acted upon by an outside force. Typically there's also the outside force of friction, which makes things tend to stop.

The function f(x) = (0.6)x is an exponential function.<br> true <br> false
Goryan [66]

False.

f(x) = 0.6x is a linear function. It is changing by the same amount per x value (0.6) An exponential function looks like this: f(x) = x^2 or f(x)=x^x
