Answer:
Step-by-step explanation:
y=(x-a)²+h
vertex (a,h)
axis of symmetry x-a=0 or x=a
x-intercepts (none)
y-intercepts (none)
graph upper parabola (don't understand what it requires )
Domain (-∞,∞)
Range [0,∞)
Answer:
(- 1, 4 ) and (2, 7 )
Step-by-step explanation:
Given the 2 equations
y = x² + 3 → (1)
y = x + 5 → (2)
Substitute y = x² + 3 into (2)
x² + 3 = x + 5 ← subtract x + 5 from both sides
x² - x - 2 = 0 ← in standard form
(x - 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 2 : y = 2 + 5 = 7 ⇒ (2, 7 )
x = - 1 : y = - 1 + 5 = 4 ⇒ (- 1, 4 )
Answer:
33.3 pounds
Step-by-step explanation:
Alright, so if she made a 100 percent on the gloves, then she sold them for 8 dollars, because 4 + 1.00(4) = 8.
48 - 8 = 40
She sold the skirt for 40 dollars, and if that's at a 20 percent profit, then we can do a proportion
If we solve for x, we figure out that x = 33.33333 repeating.
So out answer to the nearest decimal place is 33.3 pounds
