Answer:
The value of a = 3
Step-by-step explanation:
Given the function

From the attached graph, it is clear that
at x = 0,

∵ 

Thus
When x = 0, the y-intercept will be:

From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation

3 = a ∵ 
Therefore, the value of a = 3
Answer:
150
Step-by-step explanation:
Answer:
Assuming we're focusing on the shaded squares, 7/15
Step-by-step explanation:
There are 15 squares, and 7 are shaded
7/15
1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1
Answer:
15
Step-by-step explanation:
The 30-60-90 triangle rule is 2x-x-3(square root of x). Hope this helps.
