Answer:x=+3/7 or x=-3/7
Step-by-step explanation:
49x^2=9
Divide both sides by 49
49x^2 ➗ 49=9 ➗ 49
x^2=9/49
Taking the square root of both sides we get
x=±√(9/49)
x=±(3/7)
x=+3/7 or x=-3/7
Answer:
y = - 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = 
= - 2
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation of line
The data given is for the whole year of 2015, so time duration is 1 year.Convert 1 year into units of hours:
1 year = 365 days
time = 365 days * (24 hours / day) = 8760 hours
Therefore the deaths per hour is:
fatality = 33,100 / 8760 hours
fatality = 3.78 per hour
<span>In 440 , the first 4 is in the hundreds value, and the second 4 is in the tens value
When we break down the three digit of 4 - 4 - 0
We will be aware that this number came from :
400 + 40 + 0
Hundred value Tens value no value
