Answer:
Y = 2.5X + 8
Y: height (in feet)
X: time (in years)
Step-by-step explanation:
Height = 8 + 5(t/2)
= 8 + 5t/2
Height = 8 + 2.5t
Y = 2.5X + 8
<h3>
Answer:</h3>
B. (0, 9)
<h3>
Step-by-step explanation:</h3>
Reflection across x=a is represented by the transformation ...
... (x, y) ⇒(2a-x, y)
Reflection across y=b is represented by the transformation ...
... (x, y) ⇒ (x, 2b-y)
The double reflection, across x=2, y=1 will result in the transformation ...
... (x, y) ⇒ (2·2-x, y) ⇒ (4-x, 2·1-y) ⇒ (4-x, 2-y)
For (x, y) = X(4, -7), the transformed point is ...
... X''(4-4, 2-(-7)) = X''(0, 9)
Answer:
what is the blank for
Step-by-step explanation:
sorry I mean bank
(3,4) (9,7)
to find the slope
m = (y2-y1)/(x2-x1)
= (7-4)/(9-3)
3/6
1/2
The slope is 1/2
point slope form
y-y1 = m(x-x1)
y-4 = 1/2(x-3)
distribute
y-4 = 1/2x -3/2
add 4 to each side
y = 1/2 x -3/2 + 4
y = 1/2 x -3/2 + 8/2
y = 1/2 x + 5/2
this is in slope intercept form
