Answer:
y = 22
Step-by-step explanation:
Given
Slope m = (+ 11 / 5) cm/min
If P(10, y)
we can use the relation
11 / 5 = y / 10 ⇒ y = 10*11/5
⇒ y = 22
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:
15
Step-by-step explanation:
Let 'l' be the length of the other leg
Using pythagoras theorem,
25² = 20² + l²
625 = 400 + l²
225 = l²
l = 15
Answer:
the correct structure would be B
