Answer:
1/5
Step-by-step explanation:
y = kx where k is the constant of proportionality
6 = k 30
Divide each side by 30
6/30 = k 30/30
1/5 = k
The constant is 1/5
where is the question I dont see it
Answer:
28.5
Step-by-step explanation:
Answer:
( 10,20 )
Step-by-step explanation:
Y=2x
Y= 3x -10
What is the solution to the system of equations?
2x=3x-10 *combine like terms*
-1x= -10 x=10 *divide*
Y=2(10) y=20 *plug in for y into other equation*
CHECK:
plug both x and y into both equations to get a true statement.
Y=2x 20=2(10) 20=20
Y= 3x -10 20= 3(10) -10 20=20
Exponents are hard but think about it like addition, that number tells you how many times to add that number to itself. To write the equation put the number and then the exponent on the top right of that number. Your welcome!
