Answer:
7/6
Step-by-step explanation:
To find the slope of a line between two points
m = (y2-y1)/ (x2-x1)
= (6--1)/(9-3)
= (6+1)/(6)
= 7/6
Answer:
B. 45 degrees
Step-by-step explanation:
We know that the square at the bottom corner means it's 90 degrees. Since there are 180 degrees in a triangle, we could do 180 - 90. Assuming it's perfectly symmetrical, we would divide 90 ÷ 2. This means that the angle measures 45 degrees.
Answer:
29.30
Step-by-step explanation:
Note:
4.5 as a decimal is 0.045
So You can multiply 4.5% by 28 or 0.045 by 28 Either way work.
28 x 4.5%=1.26
28+1.26=29.26
Rounding:
29.30

By elimination, we can remove B and D because they lie outside of the triangle.
We know that the orthocenter is where the altitudes of a triangle intersect.
The side AB is horizontal, so you know that the altitude of AB is vertical. The altitude of AB also connects to vertex C.
Since the orthocenter must lie on the altitude of AB, and the altitude is vertical, the orthocenter must lie directly above vertex C. This means that the x-coordinate of the orthocenter is the same as the x-coordinate of vertex C.
The only choices where the x-coordinate is the same as the one for vertex C is C and D. But we eliminated choice D, meaning the answer is choice C.
<span>D = 4 - 4*9*(-7) = 4 + 252 = 256 = 16*16
x1 = (-2 + 16)/9 = 14/ 9
x2 = (-2 - 16) / 9 = -2
