Answer:
use elimination
8x-3y=2
-8x-5y=46
8x cancel out
-5y-3y= -8y= 48
48/-8= -6y
Step-by-step explanation:
ANSWER= -6y
Answer:
Step-by-step explanation:
Graph y = -3x. Start at the origin (0, 0). Place a dark dot there. Now, starting with your pencil point on that dot, move 1 space to the right and from this new point move 3 spaces down. Place a dark dot at this new point.
Now draw a straight line through both dark dots. This is the desired graph.
162.15 is the answer because you have to multiply 0.15•141 then add 21.15 to the 141 :)
Since A (3,4) A’(9,12)
You can see 3*3=9
Therefor it was enlarged by 3times
Scale factor of 3
Answer:

Step-by-step explanation:
We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.
We know that two inversely proportional quantities are in form
, where y is inversely proportional to x and k is constant of variation.
Upon substituting
and
in above equation, we will get:

Let us solve for constant of variation.


Now, we will substitute
in inversely proportion equation as:

Therefore, the formula for the given scenario would be
.
