the function of quadratic is number4
You know what a set of values is not proportional when when you divide the dependent variable by the independent variable and they all give you different answers for example
2 divided by 2 equals 2
3 divided by 2 equals 1.5
therefore those two sets of numbers are not proportional
Answer:
x = 11 , m∠2 = 31
Step-by-step explanation:
We know that m∠1 is equal to both 6x+8 and 74
Therefore, 6x+8 = 74
And 6x = 66
x = 11
To find m∠2, we just plug in the value of x that we got earlier
(7x-2) + m∠2 = 106
(77-2) + m∠2 = 106
m∠2 = 31
These angles are supplementary, meaning that their sum should be 180.
Write an equation.
5x+110=180
5x+110-110=180-110
5x=70
x=14
To find the angle measure,
multiply 5 by 14.
5 x 14= 70
To check:
70+110=180
Therefore, the variable has a value of 14.
