Answer:
wheres the graph?
Step-by-step explanation:
Answer:
y = -(x + 5)² + 4
Step-by-step explanation:
The roots are -3 and -7, so:
y = a (x + 3) (x + 7)
Distribute and complete the square:
y = a (x² + 10x + 21)
y = a (x² + 10x + 25 − 4)
y = a (x² + 10x + 25) − 4a
y = a (x + 5)² − 4a
The vertex is (-5, 4), so a = -1.
y = -(x + 5)² + 4

Step-by-step explanation:
Answer: Value of x is, 8
Step-by-step explanation:
Given: ,.....[1]
To find the value of x:
Using exponent rules:
Taking square both sides in [1] we have;
Simplify:
or
Multiply both sides by we get;
Simplify:
or
Simplify:
x = 8
Therefore, the value of x is, 8
