12.5 because a half of 100 is 50 so 12.50
Answer:
y = - 3x - 22
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 )
y = x + 1 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 6, - 4) into the partial equation
- 4 = 18 + c ⇒ c = - 4 - 18 = - 22
y = - 3x - 22 ← equation of perpendicular line
Answer:
The answer is:
C.
Step-by-step explanation:
Given:
Where is the heartbeats per minute and
is the age of person
To find:
Age of person in terms of heartbeats per minute = ?
To choose form the options:
Solution:
First of all, let us have a look at the given equation:
It is value of in terms of .
We have to find the value of in terms of .
Let us divide the equation by 0.8 on both sides:
Now, subtracting 220 from both sides:
Now, multiplying with -1 on both sides:
So, the answer is:
C.
Answer:
$10.42
Step-by-step explanation:
Compound interest formula: A=p(1+r/n)^nt
9=p, r=0.05, n=1, and t=3
A=9(1+0.05)^3
A=9(1.05)^3
Plug this into calculator and you get $10.42
The answer is B. 120+24c=500
