Heather's floor model is greater by 24 feet
Answer:
x=3
Step-by-step explanation:
-8x-(8x)=-48
-8x-8x=-48
Collect like terms
-16x=-48
Divide both sides by-16
x=3
Answer:
The vertex is (-3, 7)
Step-by-step explanation:
As the equation is already in 'rectangular form), to work out the vertex, we can just compare this equation to that of the standard parabola y = x^2, and in particular, consider how it has been translated:
the (x+3) part moves the graph the the left 3 (i.e in the negative direction), while the +7 moves the graph up 7.
So as the vertex of the simple parabola y = x^2 is (0,0), the vertex of this graph is just (-3,7).
Note that the -2 at the front doesn't impact this vertex - this -2 just changes the 'scale' of the parabola (i.e makes it more narrow, and also turns it upside down as it's a negative number).
700 is 100 times bigger than 7
hope it helps
No, it’ll be just 49 not negative 49. Because you times they by it’s self and the negatives cancel eachother !
