Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7?
StartFraction y over x EndFraction = StartFraction 7 over 10 EndFraction
StartFraction y over x EndFraction = StartFraction 1 over 7 EndFraction
x y = StartFraction 7 over 10 EndFraction
x y = StartFraction 1 over 7 EndFraction

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

that one look

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
