Answer:
Step-by-step explanation:
To find slope you have to take y2-y1 over x2-x1
y2=your second y poiny
y1=first y point
x2=second x point
x1=first x point
Since it is minus a negative you get to change it to a plus sign, because they cancel each other out.
3 + 7
____
-4-0
10/-4
This isn't quite simplified, so you find a common factor for the numerator (top number) and the denominator (bottom number). You should note the number has to go into both numbers, not just one. The largest common factor would be 2 in this case.
10/2=5
-4/2=-2
Now your simplified answer would be 5/2
Answer:
$37.86
Step-by-step explanation:
Multiply 29.99 by 0.0625 to get the sales tax
29.99x0.0625=1.87
Multiply 29.99 by 0.20 to get the tip
29.99x0.20=5.998
Round 5.998 to 6
Add 1.87 to 29.99
29.99+1.87=31.86
Add 6 to 31.86
31.86+6=37.86
Answer:
The equation of the circle is (x - 2)² + (y + 5)² = 144 ⇒ A
Step-by-step explanation:
The form of the equation of the circle is (x - h)² + (y - k)² = r², where
- r is the radius of the circle
- h, k are the coordinates of the center of the circle
Let us solve the question
∵ The center of the circle is at (2, -5)
→ From the rule above
∴ h = 2 and k = -5
∵ The radius of the circle is 12
∴ r = 12
→ Substitute the values of r, h, and k in the form of the equation above
∵ (x - 2)² + (y - -5)² = (12)²
∴ (x - 2)² + (y + 5)² = 144
∴ The equation of the circle is (x - 2)² + (y + 5)² = 144
