The vertex of this parabola at (-5,-2). When the c - value is -4 the y-value is 2 what is the coefficient of the squared express
ion in the parabolas equation. ( to answer gets brainliest )
1 answer:
Answer:
4
Step-by-step explanation:
The vertex formula of a quadratic equation is:
●y= a(x-h)^2 +k
(h,k) are the coordinates of the vertex
Here: h = -5 and k= -2
y is 2 and x is -4
● 2 = a (-4-(-5))^2 + (-2)
● 2 = a (-4+5)^2 -2
● 2 = a *1^2 -2
● 2 = a -2
● 4 = a

You can set this up as an equation and solve

The last graph. This is because he can’t fold a paper a negative number of times, it’s impossible. Hope this helped :)
Answer:
1
Step-by-step explanation:
9 goes into 9 once, so 9/9 = 1
Lemme show you a diagram
a square and the 2 sides
when 2 sides come together, they make an angle
so see diagram 1 (before cut)
diagram 2 is after cut, you get 2 triangles
6 sides, 6 angles total
