__+5>4
-3
The n and a line underneath it and then the -3 is supposed to be n over -3!! Just to help you out.... it kind of looks weird!!
-2x+6y=3
16. Tell whether the lines for each pair of equations are parallel perpendicular or neither
Y=-1/5x+6
-2x+10y= 5
Answer:
Step-by-step explanation:
15. The given lines are
Y=-3x+7 & -2x+6y=3 or, 6y = 3 + 2x or, .
The slope of the first line is -3 and the slope of the second line is [Comparing with the standard form of equation of straight line y = mx + c, where m is the slope of the straight line].
Two straight lines will said to be perpendicular to each other, if the product of its slopes will be equal to -1.
Since, , the equations are perpendicular with respect to each other.
16. The lines are and -2x + 10y = 5 or, 10y = 5 + 2x or, .
As per the question number 15, it is clear that these equations are not perpendicular.
Here, the slope of the first one is and the slope of the second one is .
The values are same with different sign. Hence, these equations are not parallel too.

A, D,
Step-by-step explanation:
1 can per 3 tennis balls are shown in the graph
1x2=2 cans
6x2=12 balls (a)
1x2=2 cans
3x2=6 balls
now im gonna do my own hw ;)
