Complete parenthesis and exponents from left to right is NOT PEMDAS.
63. all of the numbers have a square root except this one.
Answer:
46.66 or if rounded 46.7
Step-by-step explanation:
First you want to do 28x5 that would get you 140
Then, you divide 140 by 3. That would get you ur answer, Hope this helped!! :)
Ok, so user says that it should be solve for vertex not vertex form
(x,y)
to find the vertex of
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by plugging in the x value for the vertex back into the original equation and evaluating
y=-2x^2-12x-28
a=-2
b=-12
xvalue of vertex is -(-12)/(2*-2)=12/-4=-3
x value of vertex is -3
plug backin for x
y=-2x^2-12x-28
y=-2(-3)^2-12(-3)-28
y=-2(9)+36-28
y=-18+8
y=-10
yvalue is -10
x value is -3
vertex is (-3,-10)
