Answer:
The fraction of wood used for horizontal support is  .
.
Step-by-step explanation:
Assume that the total piece of wood is of length 1.
It is provided that Talia used  of the piece of wood for the base of he project.
 of the piece of wood for the base of he project.
She use  of the piece of wood for the for the vertical support.
 of the piece of wood for the for the vertical support.
The remaining wood she used for horizontal support.
The amount of wood used for horizontal support can be computed by the subtracting the amount of wood used for base of the project and vertical support form 1.
Compute the amount of wood used for horizontal support as follows:

Thus, the fraction of wood used for horizontal support is  .

Mid segment of triangle = 1/2 base
base = x here, so
1/2x = 15
multiply both sides by 2,
x=30
answer: x=30
        
             
        
        
        
Given the vertex of the parabola at point (2, -3):
The quadratic function in vertex form is:
f(x) = (x - 2)^2 - 3
where the vertex (h, k) is the minimum point = (2, -3).
        
             
        
        
        
Answer:
A
Step-by-step explanation:
-x + 2y = 8
5x + 2y = -4 
+ x. -2y. -8
6x = -12
÷6. ÷6
x = -2
5(-2) + 2y = -4
-10 + 2y = -4
+10. +10
2y = 6
÷2. ÷2
y = 3
