Answer:
Graph is option A
Step-by-step explanation:
3x + 5y = –15
To graph the equation , we need to get y alone
Subtract 3x on both sides
Divide whole equation by 5
To graph this equation , we need to make a table
Plug in some number for x and find out y
x
0 -3
-5 0
Two points on the graph is (-5,0) and (0,-3)
Graph is option A
Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.
Length of other two sides,
So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.
