In a function, each x-value must be paired with exactly one y-value.
If you can find an x-value that is paired with more than one y-value, then it’s not a function.
The quick way to find the answer is to look through all the sets and see if there’s any set that uses the same x-value more than once.
For A, the x-values are 0, 1, 2, 3.
For B, the x-values are 1, 2, 3, 4.
For C, the x-values are 2, 2, 3, 4.
For D, the x-values are 3, 4, 5, 6.
Only C has a repeated x-value.
Answer:top left corner
Step-by-step explanation:
Answer:
a) x+3=19
Step-by-step explanation:
a)
x is the age of Ronald , Collin is three years older than Ronald , so if we add up x(Ronald's age) and 3(the difference between both of their ages), we would get Collin's age(19) . That is the explanation for this equation.
b)
x+3=19
x=19-3
x=16
thus , x is 16 , in other words , Ronald's age is 16.
Answer:
65°
Step-by-step explanation:
If you add all the angles in a triangle, they equal 180°. You can subtract given angles to find missing angles.
Let's first subtract 25° from 180°. 180° - 25° = 155°.
This is a right triangle, so we know there is also a 90° angle. Also subtract this. 155° - 90° = 65°.
We are left with 65°. This is the measure of the third angle.
The triangle's angles are, 25° ; 90° ; 65°
