5) determine which lines if any, are parallel or perpendicular.Line a: y=3/5x+1
Line b: 5y=3x-2
Line c: 10x -6y =-4
Answers
Answer:
Line A and B are parallel
Step-by-step explanation:
We need to put these lines on a Graph to easily see which lines are parallel or perpendicular. To do this first we need to turn these equations into slope-intercept form (y=mx*b). At the bottom, I'll tell you where you can find more about this form.
To do this using a tool, you can search 'Graph Calculator' and using one of the graph creators, type the equations.
To do this by hand, you can isolate the Y term to the left side of the equation.
Line A: y = 3/5x + 1
Line B: 5y = 3x - 2
---> 5y / 5 = (3x - 2) /5
---> y = y = 3/5x + 1
Line C: 10x -6y =-4
---> 10x -6y -10x = -4 -10x
---> -6y / -6 = (-4 - 10x) / -6z
---> y = 0.666... + 10/6x
---> y = 10/6x + 0.666...
Here's how the graph looks after adding the lines. (Attachment below)
A is blue, B is green, and C is Purple.
Now you can see that the Line A and B are parallel. This is because if you look at the slope of these lines, they are both 3/5 (y = 3/5x + 1 and y = 3/5x + 1 ). This makes them perpendicular since the Y-intercept is different.
Slope intercept form
You can search "intro to slope intercept form" and click on one of the articles and read through if you want to know more about what Slope-intercept form is.

Answer:
y=(1/2)x-2
To graph you can use two points (I will use the x and y intercepts)
Put one point on (4, 0) and (0, -2) and you will get your line
Step-by-step explanation:
A slope of 0.5 is 1/2
in y=mx+b, m is the slope
so now we have: y=(1/2)x+b
we substitute 4 for x and 0 for y
0=1/2(4)+b which simplifies to 0=2+b
so b must be -2
this gives us y=(1/2)x-2

Answer:
40 feet of the wall will be covered.
Step-by-step explanation:
A row of plaques cover an area of 120 square feet of space on the wall.
Height of the plaques is 3 feet then we have to tell the length of the wall that will be covered.
Area of the wall covered by plaques = Length of Plaques × width of the plaques
120 = length × 3
length = 120 ÷ 3 = 40 feet.
Therefore plaques will cover 40 feet of the wall.
120 divide it by 3 to get your length.
Thus, it covers 140 ft of the wall.
