To get the vertex of the parabola we proceed as follows;
y=-7(x-4)^2-5
The above can be written as:
y=-7x^2+56x-117
The values of a,b and c are:
a=-7, b=56 and c=-117
x=-b/(2a)
x=-56/(-7*2)=4
but;
y=-7x^2+56x-117
y=-7(4)^2+56(4)-117
y=-5
Thus;
x=4 and y=-5
The vertex will be at point (4,-5)
6 multiplied by negative 7 would be negative 42. Negative 42 added by negative 8 would be negative 34.
Answer:
Step-by-step explanation:
SAS = side- angle- side
It requires two sides and the included angle be congruent.
Given one congruent side and one congruent adjacent angle.
<u>In addition to what is given we need the other side be congruent too:</u>
A = 1/2 b h
5 = 1/2 (5) h
10 = 5h
h = 10/5
h = 2
answer
2
Use a variable, x, to stand in for the number.
5+x is less than 17.
x is less than 12
Hope this helps!
