Answer:
d. about 50 times larger
Step-by-step explanation:
The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...
The larger earthquake had about 50 times the intensity of the smaller one.
M=350d+240 because the miles m is 350 per day she travels plus the 240 to pick up her cousin
Answer:
the number of deliveries would be 13
And, the equation is d ≥ 12.50
Step-by-step explanation:
The inequality function is given below:
Let us assume the d be the number of deliveries
10 × 8 + 6 × d ≥ 155
80 + 6d ≥ 155
6d ≥ 155 - 80
6d ≥ 75
d ≥ 75 ÷ 6
d ≥ 12.50
hence, the number of deliveries would be 13
And, the equation is d ≥ 12.50
The inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9
<h3>How to determine the inverse of the function?</h3>
The function is given as:
f(x) = 9x + 7
Express f(x) as y
y = 9x + 7
Swap the positions of x and y in the above equation
x = 9y + 7
Subtract 7 from both sides
9y = x - 7
Divide through by 9
y = x/9 - 7/9
Express as an inverse function
f-1(x) = x/9 - 7/9
Hence, the inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9
