2 3/5 - 1 1/3 = 2 6/15 - 1 5/15 = 1 1/5
Answer: y=7
Step-by-step explanation:
Use the vertex form to determine the values of
a
,
h
, and
k
and use these values to find the direction the parabola opens, vertex, focus, axis of symmetry, and directrix.
Direction: Opens Down
Vertex:
(
0
,
13
2
)
Focus:
(
0
,
6
)
Answer:
Not a solution.
Step-by-step explanation:
(x, y)
(-1, 2)
Substitute the x and y values in the expression with the point given.
8x + y > -6
8(-1) + 2 > -6
-8 + 2 > -6
-6 > -6
Since our final value has to be greater than -6 but is instead equal to -6, the solution is not true.
X1 = -12 , x2 = 8 ... is the answer
Answer:
96 square inches
Step-by-step explanation:
The scale is 2 inches : 3 feet
Thus for 18 feet in Serika's real house, the model is 18 * (2"/3') = 12 inches
For 12 feet in Serika's real house, the model is 12 * (2"/3') = 8 inches
Area of carpeting needed in Serika's dollhouse = 12" * 8" = 96 square inches
