Answer:
y = -1/4x^2 - x + 3
Step-by-step explanation:
(-6,0)
(-4,3)
(2,0)
36a - 6b + c = 0
16a -4b + c = 3
4a + 2b + c = 0
c = -4a - 2b
36a - 6b - 4a -2b = 0
16a - 4b -4a - 2b = 3
32a -8b = 0
12a - 6b = 3
4a - b = 0
4a - 2b = 1
b = -1
4a + 1 = 0
4a = -1
a = -1/4
c = 1 + 2 = 3
y = -1/4x^2 - x + 3
Answer:
B) false D) true E) true
Step-by-step explanation:
Plug in numbers to disprove the first one.
Area formula for triangles says D is true
It's the Pythagorean's Theorem for Heaven's sakes.
Answer:
First, estimate between two whole numbers by finding the perfect squares nearest to the target number. Next, identify which value the non-perfect square root is closer to, then use the iterative process to approximate further to the tenths place, and then further to the hundredths place.
Hope this helps!

Step-by-step explanation:
You’re Right
Orientation of a Shape is the arrangement of its points after a transformation. Translations don’t change the positions of the points relative to the shape.
A reflection would be a example of a change in orientation, since the point places will change.
I hope you understood :)
Y = 4x - 3 - x^2
now sub that in for y in the other equation
x + y = 1
x + 4x - 3 - x^2 = 1
-x^2 + 5x - 4 = 0
(-x + 1)(x - 4) = 0
-x + 1 = 0 y = 4x - 3 - x^2
-x = -1 y = 4(1) - 3 - 1^2
x = 1 y = 4 - 3 - 1 = 0
x - 4 = 0 y = 4x - 3 - x^2
x = 4 y = 4(4) - 3 - 4^2
y = 16 - 3 - 16
y = -3
points that satisfy this are : (1,0) and (4,-3)
