Answer:
<u>Equation for the relation:</u>
Let the distance covered be 'y' and the time elapsed be 'x'
We are given that y = 90 and x = 30 for a particular moment in time
dividing y by x, we get:
y / x = 90 / 30
y / x = 3
y = 3x
<u>Distance covered in 10 seconds:</u>
Speed of moving walkway = distance travelled / time taken
Speed = 90 / 30
Speed = 3 feet / second
The speed of the walkway is 3 feet per second. Which means that the walkway covers 3 feet in a second
Distance covered in 10 seconds:
from the equation: s = ut, we can find out the distance travelled in 10s
we are given: u = 3 ft/s , t = 10s
Replacing the variables
s = 3 * 10
s = 30 feet
The walkway covers 30 ft in 10 seconds
Since you took away 25% from the 100% value, we know 637.50 is 75% of the full value. So divide it by three to get the 25% value of 212.50, then multiply by 4 to get the full value of 850. So the original price was $850.
Answer:
y = -8x + 4
Step-by-step explanation:
In slope intercept form, y = mx + b, the slope is m and the y intercept is b.
Substitute -8 for m and 4 for b.
hope this helps :)
Answer:
Step-by-step explanation:
The equation of the straight line passing through the points (0,-7) and (3,-5) will be 
⇒ 
⇒
......... (1).
Now, the inequality shades the upper portion of the straight line.
Therefore, the y value for the inequality will be more than y value for the equation corresponding to a fixed value of x.
Hence, the inequality equation will be . (Answer)
