10mm=1cm
10×6=60
So 66mm is greater
66-60=6
So by 6mm
The numbers are 0.85 and 0.15

Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
Given:
Q = 0.0764 kJ = 764 J, heat input
W = -830 J, useful work done
From the 1st Law of Thermodynamics, the change in internal energy is
δE = Q - W
= 764 - (-830)
= 1594 J = 1.594 kJ
Answer: 1.59 kJ (two sig. fig.)
