Answer:
Axis of symmetry is x = -4
Step-by-step explanation:
h(x)= 5x^2+40x+ 64
Use the formula for axis of symmetry: x = -b/(2a)
Here, a = 5, b = 40, c = 64
so
x = -40/(2*5) = -40/10 = -4
Axis of symmetry is x = -4
Answer:
A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>
Step-by-step explanation:
Let convert this into slope intercept form



So now let answer these questions,
A is TRUE the slope is the number in front of the x value. It is 20 so a is true.
B is False, Using (0, 500) The equation is wrong

C is false, we have a positive slope so it shifts upward from left to right.
D is false
the slope isn't 200.
E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

It equal 50.
Bring them to the same denominator and solve for x
A and B are points on j.
C and D are points on k.
Join AD and BC.
ABCD is a quadrilateral.
Clearly, the quadrilateral ABCD is the only plane that contains the points A, B, C and D.
Hence, correct answer is option A. Exactly one.
