Assume that y varies directly with x. If y= 2/5 when x= 1/3, find y when x = 1/4
astraxan [27]

Step-by-step explanation:

y1/x1=y2/x2

2/5÷1/3=y÷1/4

y=3/10=0.3

Which is larger 80% or 1/8
d1i1m1o1n [39]

So 1/8 as a percentage is 12.5%.

80% is greater than 12/5%.

So your answer would be 80%.

HELP!!! Solve the system of equation by graphing : y=x+3 , 2x+y= -6 : also how do you know if it’s substitution or elimination?
schepotkina [342]

Either would work, but substitution looks a bit easier.

The graph for these two is shown below.


I just put the equations in just as they are written. They did not have to be changed in any way. DESMOS is a wonderful program. Very powerful.


The blue line is 2x + y = - 6

The red line is y = x + 3


The best way to solve this other than a graph is to use substitution. Put the red graph into the blue one.

2x + y = - 6

2x +(x + 3) = - 6

2x + x + 3 = - 6

3x + 3 = - 6 Subtract 3 from both sides.

3x = - 6 - 3

3x = - 9

x = -9/3

x = -3


Now go back and solve for y

y = x + 3

y = -3 + 3

y = 0


Answer

The solution point is (-3,0) just what the graph shows.
