Answer:
true
Step-by-step explanation:
If the function is odd, then f(-x) = -f(x) for all x. So if the function is defined for x > 0 it must also be defined for x < 0. So that interval is NOT possible.
This shows that she covered 0.4 miles in 10mins
<h3>Rate of change</h3>
Speed is defined as the rate of change of distance.
If it takes 24 minutes for jana to walk one mile, the rate of Jana is expressed as;
Rate= 24/1 mile
Rate = 24min/mile
In order to determine the distance she walk in 10 minutes, we will have;
Distance in 10min = 10/24
Distance in 10 min = 0.4 miles
This shows that she covered 0.4 miles in 10mins

Step-by-step explanation:
y=42
x=90
Since the triangle has the hypotenuse as the diameter of the circle, the angle opposite the hypotenuse which is x is equal to 90 degrees.
Whenever there is a triangle with the corner of the triangle touching the side of the triangle, the distance between the two legs of the triangle on the circle is 2 times the angle of the corner that is touching. So 21(2)=42
Hope this helps :)
Answer: 1.6
Step-by-step explanation:
Answer:
2/7x + 8/7
Step-by-step explanation:
f(x) = -4 + 7/2x
y = -4+7/2x
Exchange x and y
x = -4 +7/2y
Solve for y
Add 4 to each side
x+4 = -4+4 +7/2y
x+4 = 7/2y
Multiply each side by 2/7
2/7(x+4) = 2/7 * 7/2y
2/7(x+4) = y
2/7x + 8/7
