Answer:
3x-14xy+13y+4
Step-by-step explanation:
3x – 10xy + 13y – 4xy + 2x2
= 3x-14xy+13y+4
Answer: C.3
Explanation: if 5 times 3 equals 15 plus 2 is 17
A line has the following standard equation form:
y = m x + b
where m is the slope and b is the y intercept
So if Ariel cannot find the slope, then this would only
mean that m = 0, there is no slope. And hence the line is either a straight
vertical line or straight horizontal line.
Answer:
<span>There is no slope</span>
I believe you need to solve this using the quadratic formula!
To begin, this is what it is:
x= -b ± <span>√ b^2 - 4ac / 2a
Just plug in what you have in your problem...
2 being a, 13 being b, and -24 being c.
So we get:
x= -13 </span>± <span>√13^2 - 4(2)(-24) / 2(2)
x= -13 </span><span>± √169 - 8 (-24) / 4</span>
<span>x= -13 <span>± √169 + 192 / 4</span>
x= -13 </span>± √<span>361 / 4
The square root of 361 is 19.
So you have: -13 </span><span>± 19 / 4.
Here's where you take the equation </span>-13 <span>± 19 and put the addition and subtraction sign to use.
-13 - 19 = -32
and
-13 + 19 = 6
Now all is left to do is divide the two numbers by 4.
-32/4 = -8
and
6/4 = 3/2
x = -8, 3/2</span>
Answer:
Your bill is $120.80 .
10% of the total - we have to move the decimal point one space to the left: ...
20% of the total – we need to take the value of 10% and double it: ...
15% of the total – we have to divide the value of 10% by 2 and then add the result to the value of 10%:
