Answer: 10
Step-by-step explanation: When multiplying integers,
if the signs are the same, the product is positive.
So a negative times a negative always equals a positive.
Therefore, -5(-2) is 10.
Answer:
(4, 1)
Step-by-step explanation:
x^2 + y^2 - 2y - 8x - 19 = 0
We rearrange the terms and complete the square twice.
x^2 - 8x + y^2 - 2y = 19
x^2 - 8x + 16 + y^2 - 2y + 1 = 19 + 16 + 1
(x - 4)^2 + (y - 1)^2 = 6^2
The center is (4, 1)
Answer:
its the steepness of two numbers on a graph - measures the steepness of the line. (what a slope is)
y=40x+10
Step-by-step explanation:
y=mx+b
Answer:
5! and 6p3
Step-by-step explanation:
5! = 5*4*3*2*1 = 120
6p3= n!/(n-r)!
where n = 6
and r = 3
6p3 = 6!/(6-3)!
= 6*5*4*3*2*1/3*2*1
= 120
Answer:
b
