Answer:
Step-by-step explanation:
Two lines are perpendicular if the first line has a slope of 
and the second line has a slope of 
.
With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:
We now know that 
for the first line, which means that the slope of the second line is 
. With this, we have the following equation for our new line:
where 
is the Y-intercept that we now need to determine with the coordinates given in the problem statement, 
:
Finally, we can create our line:
Answer:
R290.1
Step-by-step explanation:
Let
x = charge before he put his prices up
New charge = R320
Percentage increase in price = 7%
x + 7% of x = 320
x + 0.07 * x = 320
x + 0.07x = 320
1.07x = 320
x = 320/1.07
x = 299.06542056074
Approximately
x = R290.1
Charge before he put his prices up = R290.1
Answer:
$12
Step-by-step explanation:
3 cars divide that by $18 and u get $6 per car. multiply that by two cars nd you get $12.
Answer:
x = 4
Step-by-step explanation:
f(x) = I x+1 I
when x = -5
f(-5) = I (-5) +1 I
= I -5+1 I
= |-4|
= 4
Answer: The answer to your first question would be A. 1. This is simply because anything raised to the power of 0 is 1 no matter what. The answer to your second question would be B. 1, for the same reason as above, anything to the power of 0 is 1. Hope this helped and make sure to remember that rule, it is important and easy to remember!
