Answer:
yes it is yee cause the negatives cancel out
First you can convert 45 miles per hour to feet per hour:
45 × 5,280 = 237,600 feet per hour
Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:
237,600 ÷ 60 = 3,960 feet per minute
Now you just have to divide 3,960 by 60 again to get feet per second:
3,960 ÷ 60 = 66 feet per second
Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:
66 × 3 = 198 feet
Therefore your final answer is <em>198 feet</em> :)
Answer:
Inequality: x + 4 ≥ 12
Solution: x ≥ 8
Step-by-step explanation:
<u>Plus</u>: "+" → to add something to something else
<u>Greater than or equal to</u>: "≥" → the expression on the left side of the inequality sign is greater than the expression on the right side of the sign.
Let x be the unknown number.
A number plus four is greater than or equal to twelve:
x + 4 ≥ 12
To solve the found inequality, subtract 4 from both sides:
⇒ x + 4 - 4 ≥ 12 - 4
⇒ x ≥ 8
Therefore, the solution to the inequality is x ≥ 8. The unknown number x can be any real number equal to or greater than 8.
A) y = -3000x + 25635
B) m = -3000. The slope represents the rate the Toyota 4Runner depreciates each year.
b = 25,635. The y-intercept represents the cost of the SUV before any depreciation occurred (the starting amount).
The answer is A because the rate of change is 7.
You can find this by writing it from standard form to slope intercept (y = mx+b).
B is 6, C is 5, and D is also 5 (all lower than 7)
