Answer:
Step-by-step explanation:
x intercepts are -3,-1
f(x)=-(x²+x+3x+3)=-(x²+4x)-3=-(x²+4x+4-4)-3=-(x+2)²+4-3
or f(x)=-(x+2)²+1
vertex is (-2,1)
so it is an inverted parabola with vertex (-2,1) and x-intercepts (-3,0) and (-1,0)
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
Answer:
10.4 hope this help ;) 77 x 10.4
Step-by-step explanation
turn the 10.4 into .10 then multiply like this
77 x .10 =7.7
77+ 7.7 = 84.7
These Are Less Than(<) and Greater Than(>) Symbols!!
Hope This Helps!!!
The easiest terms to check are the first (8x)(2x²) = 16x³ and the last (-5)(-6) = 30. This check eliminates the first choice. The remaining choices differ only in the sign and coefficient of the squared term, so that is the one we need to find.
The squared term will be the sum of the products of factors whose degrees total 2:
(8x)(-5x) + (-5)(2x²) = -40x² -10x² = -50x²
The appropriate choice is
16x³ -50x² -23x +30
