Answer:
-3
Step-by-step explanation:
Allison has 5 negative tiles
Next she needs to remove 2 negative tiles
What is left is 3 negative tiles
(-5) -(-2) = (-5+2)=-3
Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is

The line passes through the points (2,-1) and (1,-5). So, the equation of the line is




Using distributive property, we get


Subtract 1 from both sides.


Therefore, the correct option is B.
Let dimes = d and quarters =q
D + q = 50
D= 50-q
0.10d + 0.25Q = 7.70
Replace d with 50-q:
0.10(50-q) + 0.25q = 7.70
Simplify:
5 -0.10q + 0.25q = 7.70
5 + 0.15q = 7.70
Subtract 5 from both sides:
0.15q = 2.70
Divide both sides by 0.15:
Q = 2.70 / 0.15
Q = 18
D = 50-18 = 32
There are 32 dimes and 18 quarters
Answer:
The result is
units.
Step-by-step explanation:
The coordinates for A and B:
A = (-2, 0)
B = (2, 2)
-To find the distance between A and B, you need the distance formula:
Where the first coordinate is
and the second coordinate is
.
-Use the coordinates A and B for the equation:

-Then, you solve the equation:





So, therefore the distance is
units.
Answer:
The sum of the three angles of any triangle will always be 180 degrees because when all three angles are put together, they form a straight line.
