50:125 if you have to simplify it, it would be 1:5
Answer:
Step-by-step explanation:
60 to 15 = x to 70
60/15 = x/70.....cross multiply
15x = 4200
x = 4200/15
x = 280 <=== answer A
Hello,
y=k(x+3/2)²-25/2
and -8=k*9/4-25/2==>9/4k=9/2==>k=9/2*4/9=2
y=2(x+3/2)²-25/2
x- intercepts:
y=0=2(x+3*2)²-25/2
==>(x+3/2)²=25/4
==>x=-3/2-5/2 or x=-3/2+5/2
==>x=-4 or x=1
(-4,0) and (1,0) are x intercepts
Answer no choice!
