Answer:
D. Brandon is not correct because he should have added 6 negative unit tiles to isolate the variable in step 2
Step-by-step explanation:
Key goal is to have x on one side while the other value to the right. By subtracting 14x on both sides, you would get x+6=5. You would finally subtract 6 on both sides, not 5, to get the x by itself, thus x=-1.
Answer:
1⅚
Step-by-step explanation:
(3 + ⅔) ÷ 2
11/3 ÷ 2
11/3 × 1/2
11/6
1⅚
Answer:
x = 15.3
x = 20.9
Step-by-step explanation:
sin(46) = 11/x
⇒ x = 11/sin(46) = 15.3
cos(55) = 12/x
⇒ x = 12/cos(55) = 20.9
Answer:
69 feet
Step-by-step explanation:
we have

where
h(t) is the height of the ball
t is the time in seconds
we know that the given equation is a vertical parabola open downward
The vertex is the maximum
so
the y-coordinate of the vertex represent the maximum height of the ball
Convert the quadratic equation into vertex form
The equation in vertex form is equal to

where
(h,k) is the vertex of the parabola







the vertex is the point (2,69)
therefore
The maximum height is 69 ft
