Step-by-step explanation:
cause you go up 14 and over 6 then you divid by 2 and get 7/3
Answer:
(- 2, 0 ) and (- 4, - 2 )
Step-by-step explanation:
Given the 2 equations
y = x + 2 → (1)
y = x² + 7x + 10 → (2)
Since both equations express y in terms of x we can equate them, that is
x² + 7x + 10 = x + 2 ( subtract x + 2 from both sides )
x² + 6x + 8 = 0 ← in standard form
(x + 2)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 4 = 0 ⇒ x = - 4
Substitute these values into (1) for corresponding values of y
x = - 2 : y = - 2 + 2 = 0 ⇒ (- 2, 0 )
x = - 4 : y = - 4 + 2 = - 2 ⇒ (- 4, - 2 )
Solutions are (- 2, 0 ) and (- 4, - 2 )
We can use the pythagorean theorm. This means that the points can form the two legs of a triangle.
a = 6
b = 6
c = length AB
a^2+b^2 = c^2
2(6^2) = c^2
72 = c^2
c would be
or
Answer:
4a-3 when a=6 = 21
Step-by-step explanation:
4*6-3
4*6=24-3=21
