Y = 2x - 4 Y = x - 2 = ?
1 answer:
Answer:
the graph is below for the answer
Step-by-step explanation:
y = 2x - 4 = x=2
y = x - 2 = y=0
--------------------------------------------
step by step
Step 1: Substitute 2x−4 for y in y=x−2:
y=x−2
2x−4=x−2
2x−4+−x=x−2+−x (Add -x to both sides)
x−4=−2
x−4+4=−2+4 (Add 4 to both sides)
x=2
Step 2: Substitute 2 for x in y=2x−4:
y=2x−4
y=(2)(2)−4
y=0 (Simplify both sides of the equation)
x=2 and y=0

Answer:
When n=3 and x=−2 the answer is 11.
Step-by-step explanation:
Given:
Let p (n,x) be the function such that
To Find:
p (n,x) = p ( 3, -2) = ?
Solution:
Substituting n = 3 and x = -2 we get
Negative square gives positive number therefore (-2)²=4
When n=3 and x=−2 the answer is 11.

Answer:
48 ft
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
t = -48/(2(-16)) = 1.5
Then the maximum height is ...
f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
f(1.5) = 48
The maximum height the object will reach is 48 feet.
