Answer:
its B.429
Step-by-step explanation:
20<70
429+1=multiple of 5
429÷2=214.5
so the answer is 429
I am pretty sure the value of ‘n’ is 2.5!
(3,1)
y=-4x^2+24x-35
x-intercept of the vertex formula:
v=-b/2a
a=-4
b=24,
c=-35
v = - 24/2(-4)
v = -24/-8
v = 3
substitute x as v
y= -4(3)^2 + 24(3) - 35
y= -4(9) + 72 - 35
y = -36 +72 - 35
y = 36 - 35
y = 1
therefore the vertex is
