Maybe you can try graphing it if the graph does not have any x-intercepts than it has no real roots
Answer:
undefined
Explanation: none
Answer:
441
Step-by-step explanation:
Use a proportion.
756 miles is to 12 hours as x miles is to 7 hours
756/12 = x/7
12x = 7 * 756
12x = 5292
x = 441
Answer: 441 miles
Answer: f(x)=|2x+1|+5
f(-3) = |2*-3 + 1|+5
= |-6 + 1|+5
= |-5|+5 = 5 + 5 = 10
f(-3) = 10

Answer:
x = -9, 1
Step-by-step explanation:
(X+4)^2-25=0
Add 25 to each side
(X+4)^2-25+25=0+25
(X+4)^2=25
Take the square root of each side
sqrt((X+4)^2)=±sqrt(25)
x+4 = ±5
Separate into 2 equations
x+4 =5 x+4 =-5
Subtract 4 from each side
x+4-4=5-4 x+4-4 =-5-4
x=1 x=-9
