The red graph is the result of a vertical translation, 4 units down, of the black graph.
This means that, whenever the black graph associates
![x\mapsto f(x)](https://tex.z-dn.net/?f=x%5Cmapsto%20f%28x%29)
The red graph must associate 4 less to the same input:
![x\mapsto f(x)-4](https://tex.z-dn.net/?f=x%5Cmapsto%20f%28x%29-4)
So, the equation for the red graph is
![y=f(x)-4](https://tex.z-dn.net/?f=y%3Df%28x%29-4)
or, equivalently,
![y+4=f(x)](https://tex.z-dn.net/?f=y%2B4%3Df%28x%29)
Perimeter = length + length + width + width.
7y-7.5 + 7y-7.5 + 7.5y+8 + 7.5y +8
Combine like terms:
29y+1
The perimeter is 29y + 1 feet
Answer:
A. y(3) + x = total cost
B. Shoe rental is $2.
Step-by-step explanation:
A. 4(3) + 2 = 14
B. If 4(3) = 12, and the total cost is $14. Then the shoes cost $2.
4(3) = 12 + 2 = 14
all of them except the last efg and bcd
Answer:
The intensity of the first earthquake is 6.31 times the second one
Step-by-step explanation:
The given formulae is M=log(
)
Here for both the earthquakes the value of S is same.
Let the Intensity of the first earthquake be I1 and the second be I2.
Given M1=7.5
M2=6.7
Now M1=log(
)------1
M2=log(
)-----2
Now subtract 1 and 2 we get
M1-M2=log(
)
I1/I2=![10^{M1-M2}](https://tex.z-dn.net/?f=10%5E%7BM1-M2%7D)
I1=I2(![10^{0.8}](https://tex.z-dn.net/?f=10%5E%7B0.8%7D)
I1=I2*6.31
