Which system of equations is shown by the graph
natta225 [31]

Answer:

The third or bottom left option.

Step-by-step explanation:

Pay attention to the slopes. If it is negative that the graph points to the top left or bottom right and the opposite for a positive slope(slope is the coefficient of the x value meaning if the slope is a very small negative number or a large positive number than the steepness changes) This can be solved purely through the process of elimination which is how I did it.

Two quantities, x and y, are directly proportional. If x is doubled, what happens to y?
vagabundo [1.1K]

Answer:

y is also doubled.

Step-by-step explanation:

Direct proportionality between x and y means that

y \propto x

or

y=cx,

which indicates a linear relationship between  x and y because they are related by a constant.

Therefore, if x is doubled, then the new value of y is y_{new}

y_{new}=c(2x)

y_{new}=2(cx)

y_{new}=2y

The new value of y is 2 times the previous; therefore, y is doubled as x is doubled.

faust18 [17]

9514 1404 393

Answer:

  4 : 7

Step-by-step explanation:

The ratio of perimeters is exactly the same as the ratio of side lengths. Multiplying each side by 7/4 multiplies the sum of the sides by 7/4.

The ratio of perimeters is 4 : 7.
