39 algebra. , i am failing and this is due in an hour.

Question 10: Question 13: Question 11:

Step-by-step explanation:

For Question 10:

The functionis in the form of . We know the slope is (rise 1 run 2)and the y intercept is -1 (where the line goes through the y axis). We can then put the function is slope intercept form () and we would have .

For Question 13:

To evaluate the function for we need to plug -2 into the function as x. . times -2 would equal 3 because the negatives cancle out. 3-4 equals -1 so the solution is .

For question 11:

Same as question 13. plug 8 into x in . This would be . 8 squared is 64 and 64-4 is 60. Therefore .

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
