Answer:

x=10 , y=7

Step-by-step explanation:

x + y = 17

we know that ducks has 2 feet and sheep has 4 feet.

so, 2x + 4y = 48

x = 17 -y

2(17-y) + 4y = 48

34 - 2y + 4y = 48

2y = 48 -3 4

2y =1 4

y=7

x + 7 = 17

x = 17-7

x=10

Which equation represents a line that is parallel to the line whose equation is 2y=3x+7 ?
Sav [38]
2 and 4. In equations where the line is parallel, the slope is the same. By eyeing this number 2 is right but number four is right as well because when you put y by itself and divide the 2 from the whole equation, it is ultimately the same and still parallel from the original equation.

Answer:

<em>y-intercept - </em><em>(0,275)</em>

<em>x-intercept - </em><em>(125,0)</em>

The intercepts are the points on the graph where the line goes through. Here, the line goes through approx. <em>275</em> on the y-axis, giving you the <em>y-intercept.</em>

Same with the x-axis - the line goes through approx. <em>125</em>
