Liar. This is only worth 5 points!!!!!!!!!!!!!!!!!!!!
It would be the girls because 7 divided into 21 equally is 3. So there will be 7 groups of 3 girls.
6x-32 is the expression that you are looking for
7x+(x+20)=180
Just simplify. Hope this helped:)
Answer:
A and A
the equation of a parabola in vertex form is
y = a(x - h)² + k
where ( h, k ) are the coordinates of the vertex and a is a multiplier
y = - 2(x + 3)² + 2 is in this form
with vertex = ( - 3, 2)
To find the y-intercept let x = 0
y = - 2(3)² + 2 = - 18 + 2 = - 16
Similarly
y = - 2(x + 2)² + 2 is in vertex form
vertex = ( - 2 , 2)
x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept
hope this helped
