Answer:
x=36 y=48
Step-by-step explanation:
Answer:
<u>explanation</u>:
solving similarities:
bigger triangle is double of the smaller triangle.
<u>balancing them</u>:
→ x + 9 = 2(2x - 3)
→ x + 9 = 4x - 6
→ 4x - x = 9 + 6
→ 3x = 15
→ x = 5
Axis of symmetry is x = 6
One of the roots is -1.5
On the graph, -1.5 is to the left of the axis of symmetry by 7.5 units. If we were to go 7.5 units the opposite direction from the axis of symmetry (right), we would get the other root. Simply:
6 + 7.5 = 13.5
Therefore the other root would be 13.5.
Hope this helps! :)
Answer:
r is greater than or equal to 2.5
Step-by-step explanation:
Answer: The numbers are 14 2/3 and 43 1/3 (you can also write it as 44/3 and 130/3)
Step-by-step explanation:
x+y=58
2y-4x=28
This is a system of equations, so you can make the y equal to each other by: 2x+2y=116
Now you can subtract the equations from each other, so you have
2x+2y=116
-(2y-4x)=28
The y cancels out, leaving you with 6x=88, so x=14 2/3
When you plug x in, you get y=43 1/3
