Hello,
Equation is y=k(x-1)²-9
and when x=0,y=-6==>-6=k*1²-9==>k=3
y=3(x-1)²-9
when y=0, 3(x-1)²-9=0
==>(x-1-√3)(x-1+√3)=0
x-intercepts are (1+√3,0) and (1-√3,0)
Answer B.
3(n-7)=-30
3n-21= -30
3n = -9
n= -3
Answer:
x+y=-2
7x-4y=8
Step-by-step explanation:
You can make it with 10 because 10%times 5% is 50%
B/5 > 30
we’re going to simplify by multiplying by 5 on both sides.
b > 150 should be the answer!
