17 is a prime number whereas 26,44 and 65 are the composite numbers.
<u>Step-by-step explanation:</u>
The number 17 does not belong with 26, 44 and 65.
Here 26 is divisible by 2 and 13.
44 is divisible by 2, 4 and 11.
65 is divisible by 5 and 13
But 17 is divisible by 1 and itself, that is it's a prime number, whereas the other numbers 26, 44 and 65 is divided by 1, itself and also by other numbers.
So 17 is a prime number whereas the 65, 26 and 44 are composite numbers.
If i understand correctly your answer is A. Hope i helped :-)
Answer:
6/7
Step-by-step explanation:
The constant rate of change is also know as the slope of the expression
Given
24x-28y=14
Write in standard form y = mx+c
m is the slope
24x-28y=14
-28y = -24x + 14
y = -24x/-28 + 14/-28
y = 6/7 x - 1/2
Compare
mx = 6/7 x
m = 6/7
Hence the constant rate of change is 6/7
Answer:
Equation: y=7x
y=-28
Step-by-step explanation:
y=kx
y=98
x=14
98=14k
98/14=7
k=7
Equation: y=7x
x=-4
y=7•-4
y=-28
Answer: The sailboat is at a distance of 15 km from the port.
Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.
We are to find the distance between the sailboat from the port in kilometers.
Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.
The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.
PS = ?
Using the Pythagoras theorem, we have from right-angled triangle SOP,
Thus, the sailboat is at a distance of 15 km from the port.
