Answer:
always
Step-by-step explanation:
with 4 sides you can conclude that every quadrilateral is going to have 2 pairs of opposite sides. the opposite sides might not be equal, but they will be there.
Answer:
Step-by-step explanation:
If the liquid is cooling at a constant rate, then the equation for this is linear. We can use the info given to find the linear equation for this situation. We have 2 points: (2, 178) and (5, 154), where the x coordinate represents the time in minutes, and y represents the temperature. We use these values in the slope formula:
Now we will use one of the points to finish writing the equation. I chose (2, 178), but it doesn't matter which one you choose; they will both give you the same equation in the end.
y - 178 = -8(x - 2) and
y - 178 = -8x + 16 so
y = -8x + 196
If we are looking for the temp when the liquid starting cooling, then we are looking for the temp at time 0, or when x = 0 (sincce x is our time).
y = -8(0) + 196 so
y = 196
That's the temp of the liquid before it started any cooling.
Answer:
Step-by-step explanation:
So to find the equation of this line we must first find the slope
to find the slope with two points you do y2-y1/x2=x1
so (0+3)/(-3-16)
-3/19ths will be your slope
Now we have one part of the equation, we still need to find the y intercept. Remember the slope intercept equation goes like this: y=mx+b. Where m is your slope and b is your y-intercept. So in order to find the y-intercept, we just use one of the points already given and solve for b
like so:
0=-3/19(-3)+b
-3 -3 = 9
19 1 19
0 = 9/19+b
subtract 9/19 from both sides
and b is -9/19
so your equation will go like this: y=-3/19x-9/19
