Answer:
13 chairs in each row
Step-by-step explanation:
divide 65 by 5 to get 13
Answer:
(-5,2)
Step-by-step explanation:
It alogns with negative 5 on the X axis, and positive 2 on the Y axis, meaning its written as (-5,2)
-3x+7y=5 (x2) -> -6x+14y=10
-6x+14y=10
-8x+14y=-10
——————— -
2x=20
x=20/20
x=1
Susbstitute x=1,
-8x+14y=-10
-8(1)+14y=-10
-8+14y=-10
14y=-10+8
14y=-2
y=-2/14
y=-1/7

So, we know the slope equation y = mx + b. The b value represents the y intercept, which is the point where the line intersects the y axis. This means that the x value will always be 0. In this equation, the y-intercept is -2, so the y intercept as an ordered pair is : (0, -2). For the x intercept, there are several ways of doing it. For this problem, we can work backwards. There is a slope of 6 units down for every unit right. Starting from our y intercept, we can do the opposite: 6 units up for every unit left. this means our x intercept is -0.3. As an ordered pair, this is (-0.3, 0).
