Answer:
2500
Step-by-step explanation:
let a represent the number of people that had swine flu on the 8th of May
a increased by 37.6% on the 9th of May. The 37.6% increase is equal to 3440
the equation that can be used to represent this is:
a x 1.376 = 3440
to find a, divide both sides by 1.376
a = 2500
Answer:
y = -2x + 25
Step-by-step explanation:
A standard equation can be in slope-intercept form: y = mx + b
m is the slope, b is the y-intercept.
Plug in the given slope.
y = -2x + b
To find b, plug in the given point (9, 7).
7 = -2(9) + b
Multiply.
7 = -18 + b
Add 18 to both sides to find b.
25 = b
Plug this into your standard equation.
y = -2x + 25
Check by plugging in the given point again.
7 = -2(9) + 25
7 = -18 + 25
7 = 7
Your answer is correct!
Hope this helps!
Answer:
x = 3.2
Step-by-step explanation:
5x + 8 = 24
5x = 16
5+5+5+1
1 is a 1/5 or .2 of a 5
x = 3.2
So, therefore, x would be 3.2
Answer:
Option B.
Step-by-step explanation:
If a quadratic equation is defined as 
, the by quadratic formula
Consider the given equation is
We need to find the value of x.
Add 96 on both sides.
Here, a=1, b=14 and c=113. Using quadratic formula we get
The value of x are x=-7 + 8i and x=-7 - 8i.
Therefore, the correct option is B.
