This value of "a" is exactly the y-coordinate of the vertex of the parabola
y = x%5E2+%2B+4x++-+31.
To find it, complete the square:
x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.
So, this value of "a" is a = -35.
Figure. Plot y = x%5E2+%2B+4x++-+31.
Answer:
27⊂14=7
Step-by-step explanation:
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
For the first problem, your answer is D, 16, because -5+8=3, and 3+ |-13|=16, because the absolute value of -13=13
for the 2nd, B is the correct answer. -4.37 is smaller than -1.63,
the 3rd one is C, 19. -14+19=5,
the 4th one the answer is D, -20.1 because 12.7+ -20.1=-7.4
1=D
2=B
3=C
4=D
