The equation describing variation will be found as follows:
zαxy
z=kxy
where k is the proportionality constant
k=z/xy
when x=3, y=-5 then z=-75
k=-75/(-5*3)=5
hence the formula will be:
z=5xy
Answer:
-18
Step-by-step explanation:
Coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
M = (7,6)
Step-by-step explanation:
formula to find mindpoint is
(4,2) = (x1, y1)
(10,10) = (x2,y2)
now substitute those into the formula!
now solve for x & y !!
so now that we have solved for x & y put it in point form and your done !!
point for is (x,y)
and thanks why the Midpoint is (7,6)
Answer:
Step-by-step explanation:
All you have to do for this is follow PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Substraction) Which is the order of operations.
First you do parenthesis, , when you have a positive exponent outside a parenthesis like this, you add them together, and in this case, you get,
After that, you do the rest of the exponents as well as multiplication, .
Now we plug in the 81 from our last step along with the 16 from the first step and multiply them together.
Then you just simply need to find which of the answers come out to be the result we got which is 1296. Out of these 4 possible answers, ends up being equal to 1296 which means that is the correct answer.
