Hello,
y=k(x-1)²-9
and -6=k*1-9==>k=3
y=3(x-1)²-9
y=0==>3(x-1)²=9==>(x-1)²=3
==>x=1+√3 or x=1-√3
x-intercepts are (1+√3,0) (1-√3,0)
Answer:
9.2
Step-by-step explanation:
first i added 5 + 3 = 8
then i did 1 1/5 + 8=9 1/5
Answer:
RT = 20
Step-by-step explanation:
Given S is at the midpoint of RT , then
RS = ST , that is
7y - 4 = 2y + 6 ( subtract 2y from both sides )
5y - 4 = 6 ( add 4 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
Then
RT = RS + ST = 7y - 4 + 2y + 6 = 9y + 2 = 9(2) + 2 = 18 + 2 = 20
Answer:
Step-by-step explanation:
Compare and contrast oceanographers and geologists.
If you pour out 1/4 of the water and it’s 7 gallons, then 7 x 4 ( or 7/.25) = 28 gallons.
