Answer:
3.4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Slope is the fraction, or ratio, of the vertical change over the horizontal change of two sets of data. In this case, the slope is the rate at which the house rises over expands:
Simplifying the fraction to simplest form gives an overall rate of 1/6 ft.
1 Light Year =
miles
The distance of star from the Earth in Light Years =
Light Years.
The distance of star from the Earth in miles will be:
Thus, the star is approximately miles from the Earth.
Answer: (-2,5)
Step 1: Rewrite equations
-3x+2y=16
x-2y=-12
Step 2: Changing the second equation
With substitution, you have to already have the equation to solve for the specific variable (ex: x=y+1;y=x+1). Since the equation doesn’t give us one, we can flip the second equation to give us this.
Let’s add 2y on both sides.
x-2y=-12
+2y +2y
_________
x=2y-12
Now we have the equation to solve for x!
Step 3: Substituting
Now we need to substitute x into the first equation. Let’s do this now.
-3(2y-12)+2y=16
Step 4: Solving for y
-3(2y-12)+2y=16
*distribute*
-6y+36+2y=16
*combine like terms*
-4y+36=16
*subtract 36 on both sides*
-4y=-20
*divide both numbers by -4*
y=5
This is y! Now we need to solve for x.
Step 5: Solving for x
To find x, let’s just substitute y into the equation and solve
x=2y-12
x=2(5)-12
x=10-12
x=-2
Step 6: Ordered pair
(X,y) —> (-2,5)
This is your answer! Hope this helps comment below for more questions :)
