Step-by-step explanation:
because ther is only on car the value 5 could be constant. but because there could be a number of people in the car that is described by x and is multiplied by the cost which is 1
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. Use the graph to find the range.
Step-by-step explanation:
Explanation: y=7 is a straight line with zero slope and y-intercept 7 as shown below. Hence its domain (all allowed x-values) is all real numbers, and its range (all allowed y-values) is only 7.

Answer:
It would take 0.0977 seconds to go 1 meter at that speed
From the first two inference, it takes her phone 1 minute to charge 2% i.e 1 minute of charge = 2% of battery.
Therefore; charging from scratch,
1 min = 2%
x mins = 50%.
using cross multiplication,
x mins = (50% × 1 min) ÷ 2%.
x = 25 mins.
For 90%, applying the same formula,
y min = (90% × 1 min) ÷ 2%
y = 45 mins.
So from zero percent, it will take Dana's phone 25 minutes to charge to 50% and 45 minutes to charge to 90%.
Answer:
Step-by-step explanation:
Plot the points and connect in pairs.
We got a right triangle.
<u>The legs have the length:</u>
- 1 - (-2) = 3 units and
- 1 - (-3) = 4 units
<u>The area of the triangle is:</u>
- A = 1/2bh
- A = 1/2*3*4 = 6 square unit
