Answer:
n -8.2 = 2.3(t -1)
Step-by-step explanation:
You are given definitions for the variables t and n, along with two data points:
(t, n) = (1, 8.2) and (5, 17.4)
The slope of the line between these points is ...
m = (y2 -y1)/(x2 -x1)
m = (17.4 -8.2)/(5 -1) = 9.2/4 = 2.3
The equation can be written in point-slope form as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
n -8.2 = 2.3(t -1) . . . . a linear model describing the data
______
<em>Additional comment</em>
If we eliminate the parentheses and add 8.2, we get the point-slope equation ...
n = 2.3t +5.9
Since triangle ABC is a isosceles triangle
∠ABD = 66°
(Base angle of isosceles triangle)
∠BAC = 180° - (66° × 2) = 48°
y = 48° ÷ 2 = 24°
z = 90°
Answer is C.
the answer is -3g that's what I got
Answer:
(-5, 2).
Step-by-step explanation:
Working backwards
Move up 3 units (-5, 1) ---> ( -5, 4)
Move down 2 units (-5, 4) ----> (-5, 2).
