Y = a(x - h)² + k • (h, k) is the vertex • x = h is line of symmetry so y = ax² - 2x - 3 y/a = x² - 2/ax - 3/a y/a + 3/a = x² - 2/ax y/a + 4/a= x² - 2/ax + (-1/a)² ← completing the square y/a + 4/a= (x - 1/a)² y/a = (x - 1/a)² - 4/a y = a(x - 1/a)² - 4 so since you've been given h = 1 then 1/a = 1 and so a = 1
Yes, the equation specifies a function with independent variable x.
Equation: 6x + 19y = 7
This can be put in y = mx + b form,
6x + 19y = 7
19y = -6x + 7
y = -
x + 
Since the equation can be put in the form of a linear function, the domain is all read numbers (-∞,∞) or -∞ < x < ∞ .

Answer:
X = 11.5
Step-by-step explanation:
Check your work: 6 x 11.5 - 9 = 60
(it’s 60 because the triangle is congruent.)
