Answer:
B: 280
Step-by-step explanation:
The regression line predicts that when x equals 5:

In order to find the value for y, one must simply apply the following logarithmic property:
if :
then: 
Applying it to this particular problem:

Therefore, the regression line predicts y will equal 280 when x equals 5.
Answer: Y = 10
Step-by-step explanation:
Because it is a horizontal line, the equation will just be Y = the Y value
Answer:
Top question: -7°
Bottom question : 18°
Step-by-step explanation:
Top question:
The base angles of am isosceles triangle are congruent:
x + 46 = 39 because the base angles of an isosceles triangle are congruent
x + 46° = 39°
x = -7°
Bottom question
The missing angle is 3x because the base angles are congruent
To find the value of x, we must add all the angles inside the triangle, and find the value of x that makes it equal to 180°
3x + 3x + 4x = 180°
10x = 180°
x = 18°

Hello!
As you can see,this triangle has a 97° angle, which means it is obtuse. As you can see, all of the lines are different lengths, so it is scalene.
Therefore, our answer is B) obtuse, scalene.
I hope this helps!
