Answer:
0.56
Step-by-step explanation:
14 divided by 25 is 0.56
Answer: x ≥ 4
<u>Step-by-step explanation:</u>
x + 10 ≥ 14
Subtract 10 from both sides of the equation:
x ≥ 4
Graphing:
> and < symbols represent an open dot
≥ and ≤ symbols represent a closed dot
Since the solution is: x ≥ 4, we will use a closed dot and the arrow will point to the right of 4.

Answer:
37.5 miles per hour
Step-by-step explanation:
The traffic along a stretch road moves at an average speed that carried inversely as the number of cars
Average speed= k/number of cars.
When there are 1,500 cars the average speed is 45
The first step is to calculate the constant k
45= k/1500
k = 1,500 × 45
k= 67,500
Therefore the average speed when there are 1,800 cars can be calculated as follows
Average speed= 67,500/1,800
= 37.5 miles per hour
Hence the average speed is 37.5 moles per hour
Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
