Answer:
the answer is
Step-by-step explanation:
1= A(3, 2) B (1, -1) C(4, -2)
2= A(3, 8) B(1, 5) C(4, 4)
3= A(3, -4) B(1, -7) C(4, -8)
4= A(7, 2) B(5, -1) C(8, -2)
5= A(-1, 2) B(-3, -1) C(0, -2)
Answer:
Step-by-step explanation:
the y- intercept is at -3 so is either
y= x-3 or y=2x -3
the x-intercept is at 2 so when y=0, x must be 2
0= x-3 so x=3
0=2x-3 so 2x=3 and x=3/2
in conclusion none of the equations given are the graphed
FYI the equation for the graphed line is
y= 3/2 x-3
A sample of mercury-conductor
A piece of glass-insulator
A rubber hose-insulator
A negatively ionized lithium paste-conductor
<u>Step-by-step explanation:</u>
Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.
Mercury is a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.
Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.
Answer:
QT < TR.
Step-by-step explanation:
QT = TR because TZ is a mid segment so QT < TR is false.
Question 1: The y-intercept is where the line crosses the y-axis. The increments of the y-axis is by 20, and the y-intercept is at (0, 20).
The slope is the change in y over the change in x. Find two points:
(0, 20) and (2, 80)
Now:
(80 - 20)/(2 - 0) = 60/2 = 30
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
So:
y = 30x + 20
Question 2: Again, look for the y-intercept, which is pretty clear. It's (0, 60).
Now find two points:
(0, 60) and (2, 40)
Find the slope:
(40 - 60)/(2 - 0) = -20/2 = -10
So, the equation is:
y = -10x + 60
And, there you go!
