Answer:
Step-by-step explanation:
5, -4
5-4=1
5(-4)=-20
Answer:
B. Square root
Step-by-step explanation:
using distance formula:
x = √z^2 - y^2
y = √z^2 - x^2
=> z = √x^2 + y^2
Answer:
y = -x + 9
Step-by-step explanation:
The line that passes through the points (-2,4) and (0,6) has a slope of 1, and a y intercept of 6. The equation to the first line is y = x + 6. and perpendicular lines always have the opposite, reciprocal slope of the other line. So the slope for the second line would be -1. A line with the slope of -1 and a point of (5,4) would contain the points (5,4) , (4,5) , (3,6) , (2,7) , (1,8) , and (0,9) , which is the y intercept for the second line. So the equation for the second line would be y = -x + 9
-5.9, -5 7/8, 5.78 because negative is less than zero and 7/8= .850 :)
It would be:1/x = 1/40+1/52 = 13+10/520 = 23/520
x = 520/23 = 22.60 minutes
