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.
Answer:
C
Step-by-step explanation:
I used the formula. it took a long but i got it! Brainly pls!
6(7n – 5m) + 8m
42n - 30m + 8m
42n -22m
Answer: 42n-22m
No, because
60/3 = 20
90/6= 15
Both of the answers aren’t equivalent.
We know that 60 minutes = 1 hour and 1 mile = 5280 feet. We just need to multiply and simplify:
651 miles/hour = 651 *5280/60 feet/minutes = 651*88 feet/minutes = 57288 feet/minutes
