11 girls to 15 which is the total number of band students.
<u>Answer:</u>
f(x) = 7 is an even function.
<u>Step-by-step explanation:</u>
Any function is even when 
and gives a graph that is symmetric with respect to the y-axis.
We are given these options and we have to check whether which of them is an even function:
and 
- This function is not even
and 
- This function is not even
and 
- This function is not even
and 
- EVEN FUNCTION
We get the same value for 
and 
, therefore f(x) = 7 is an even function.
Answer:
D
Step-by-step explanation:
use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)
we're given that m=2 and the point is (2,9)
Substitute into the equation
y-9=2(x-2)
That means that the answer is D
Hope this helps!
Answer:
3. m∠1 = 106° ~ this is because ∠1 and ∠2 together make a straight line and are therefore supplementary, meaning added together, they equal 180° (so I did 180° - 74° = 106°)
4. m∠3 = 74° ~ again, it is supplementary to ∠1. It is also equal to ∠2
5. m∠8 = 114° ~ angles opposite of each other (like 1 and 4) are equal (as we know from question 4). From there, we can use the corresponding angle theorem, so we know 4 and 8 are congruent. (also you can just know 1 and 8 are congruent by using the opposite exterior angles theorem)
6. m∠6 = 124° ~ using same-side interior angle theorem, they are supplementary angles (or the corresponding angles theorem mentioned above, make 4 congruent to 8, and 8 is supplementary to 6)
7. m∠7 = 96° ~ using same side exterior angle theorem, these angles are supplementary
8. m∠2 = 64° ~ again, same side exterior angle theorem
