Answer:
slope is -1
Step-by-step explanation:
Slope of the line (m)=(y2 -y1)/(x2 -x1)
given
(x1, y1)=(-4 , 5)
(x2,y2)=(-7 , 8)
Now using the above formula
m =(8-5)/(-7-(-4))
m = (3)/(-7+4)
m= 3/(-3)
m=-1
therefore the slope of the line is -1
Step-by-step explanation:
Given:
Wavelength of wave : 3.3m
Frequency of wave : 100Hz.
speed/velocity : ?
As we know
velocity = wavelength × Frequency
= 3.3 × 100
=330ms−1
So the speed of the wave is 330 ms·¹
Answer:
12
Step-by-step explanation:
b-4x
Plug in 4 as b and -2 as x
= (4)-4(-2)
Multiply 4 and 2
= 4-(-8)
Two negatives make a positive
= 4+8
= 12
I hope this helps!
The equation for the graph is m=250-25w
Answer:
False
Step-by-step explanation:
If Monica just adds 8 to the week number the values she would get would not equal those presented in the chart. Therefore this statement cannot be true.
