answer is 7 pigs and 4 chicks
pigs' legs = 7 x 4 = 28
chicks' legs = 4 x 2 = 8
28 + 8 = 36 legs
Answer:
31-17/10*4
Step-by-step explanation:
The difference of is subtraction
Divided is division
The product of is multiplication
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: ![x=\frac{4}{2*2}=\frac{4}{4}=1](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B4%7D%7B2%2A2%7D%3D%5Cfrac%7B4%7D%7B4%7D%3D1%20)
y = 4x^2 + 8x + 3: ![x=\frac{-8}{2*4}=\frac{-8}{8}=-1](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B-8%7D%7B2%2A4%7D%3D%5Cfrac%7B-8%7D%7B8%7D%3D-1%20)
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
<span>The function f is defined by f(x)=x^2+3x-10 If f(x+5)=x^2+kx+30, k= Find the smallest zero of f(x+5), x=
By definition, the zero of a polynomial function is a number a such that f(a)=0. For quadratic equation, the zeros can be found on equalizing f to 0. First, f(x+5)=(x+5)²+3(x+5)-10=x²+10x+25+3x+15-10=x²+13x+30, and it is told that If f(x+5)=x^2+kx+30 = x²+13x+30, it implies k=13, so let’s find the zeros. x²+13x+30=0 is to solve: D= 13²-4x1x30=169-120=49, sqrt49=7, so x=-13-7 / 2=-20/2 = -10, and x= -13+7/ 2 = -6 /2= -3. Obviously, we know that -10< -3, so the smallest zero is -10.
