Answer: C. 1.5
Step-by-step explanation:
There is only one intercept at the origin - coordinates (0, 0).
We have the function f(x)=x²
Let y = x² We have to find out the x-intercept and the y-intercept
an x-intercept is a point on the graph where y=0 ⇒ x²=0 ⇒ x=0 ⇒ O(0,0) - x-intercept
a y-intercept is a point on the graph where x=0 ⇒y=0 ⇒ O(0,0) - y-intercept
↓
The function has only one intercept : O(0,0) as it is shown in the graph below ↓
7 kilometers per 1 week equals 8.75 kilometers per x weeks.
7 / 1 = 8.75 / x
7 = 8.75 / x
7x = 8.75
x = 8.75 / 7
x = 1.25
It took 1.25 weeks to build 8.75 kilometers of road.
The construction crew would need approximately 1.25 weeks to build 8.75 kilometers of road. This is calculated by dividing the total distance by the rate of construction.
To find out how many weeks it took the construction crew to build 8.75 kilometers of road, we need to divide the total distance (8.75 km) by the rate at which they built the road (7 km per week). So, the calculation will be 8.75 km ÷ 7 km/week.
This is a simple division problem. Using a calculator, you will find that 8.75 ÷ 7 equals approximately 1.25.
Therefore, the construction crew would need about 1.25 weeks to build 8.75 kilometers of road. Please note, this is an approximation, and actual times may vary.
