5y- 2y because pemdas says go left to right when having the same symbol and they are compatible because they are the same 5y-2y is -3 and then minus 9x-0x this only gets rid of the x so now you have just 9 so were left with -3/9 I’m not sure what your slash is but here are the possible answers
If slash is addition it is 6
If slash is subtraction it is -12
If slash is multiplication it is -27
If slash is division it is -0.333
Answer:
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
<em></em>
Step-by-step explanation:
Total number of coins = 43
Let number of nickels = n
Let number of dimes = d
Let number of quarters = q
Money in n nickels = 
Money in d dimes = 
Money in q quarters = 
Total money = $7.45
The sum of the numbers of nickels and dimes is 3 less than the number of quarters.
i.e.
Let us put the value in (1):
Putting the value of q in (1) and (2):
n+d = 20 .... (3)
(4) - (3):
d = 14
Now, from (3):
n = 6
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
2 and 1/3 would be your answer
Answer:
Terminal point (0, -1); sin Ø = -1 ⇒ A
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis
- The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0
- The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1
- The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0
- The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1
In a unit circle
∵ Ф = 270°
→ By using the 4th rule above
∴ The terminal point is (0, -1)
∴ sinФ = -1
∴ Terminal point (0, -1); sin Ø = -1
There will be no angle between the lines as the lines are parallel.
We are given the two lines:
2 x - 3 y + 5 = 0 and 2 x - 3 y - 7 = 0
Slope of the line 2 x - 3 y + 5 = 0:
-a₁/b₁ = -2/-3 = 2/3
Slope of the line 2 x - 3 y - 7 = 0
-a₂/b₂ = -2 / -3 = 2/3
Since both the lines have same slopes, they are parallel lines and will not intersect each other.
So, there will be no angle between the lines.
