The Scale factor from 6in to 10ft is 24
Y = -3x - 40. Use the distributive property to get the slope and move the 10 to the other side to isolate the y
Answer:
0.00138516
Step-by-step explanation:
Answer:side one is 8cm
Side 2 is 8cm
Side 3 is 15 cm
Step-by-step explanation:
The perimeter of a shape is the distance around the shape. The perimeter of a triangle is the sum of the sides of the triangle.
Let x represent the length of side one and side 2. Since they have equal length, the sum of their length is x + x = 2x cm
Side three is one cm shorter then twice the length of side one. This means that the length of side three would be 2x - 1
The perimeter of a triangle is 31cm. Therefore,
2x + 2x - 1 = 31
4x - 1 = 31
4x = 31 + 1 = 32
x = 32/4 = 8 cm
Side three = 2×8 - 1 = 16 - 1 = 15
Plug in (1,8) to y ≤ 2x+2 and you get 8 ≤ 2+2 which is not true
