X/2-15=-7
x-30=-14
x=-14+30
x=16
Answer:
64
Step-by-step explanation:
(15-7) is 8 and (5+3) is 8 so 8 times 8 is 64
Answer:
x= 2
Step-by-step explanation:
hello :
y= -5x²+20x a= -5 b= 20
the axis symmetry is the line when an equation is : x = -b/2a
x= -(20)/2(-5)
x= 2
5(1/2)-2(2/3)=11/2-8/3=(11*3)/(2*3)-(8*2)/(3*2)=(3*11-2*8)/6=(33-16)/6=17/6=2(5/6)
so the answer is 17/6 or 2(5/6)
