Answer:
1) 5 2) 7 3) 9 4) 8
Step-by-step explanation:
you add and subtract the numbers, for example, number 1, the total is 9 and it shows 4 so 5. Or 3, K to I is 3 and 11 (the total) minus 3 equals 8, plus the 1 so 9. Hope this helps! Have a good day! :)
Answer:
The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4
Step-by-step explanation:
Given
Solving (a): The vertex;
Assume the general form of a function is
The vertex is determined by
By comparison, we have:
Solve for h, we have:
So, the vertex is:
The domain; x is all real numbers
From the function;
This can be rewritten as:
This implies that:
Whatever the value of is, it will be subtracted from 4 to give y or f(x);
Hence:
y is less than 4

Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m = = = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
