0.9x = 450
x = 450/0.9
x = 500
Answer = 500
Its not a function because there are two ages that are the same.
The slope-intercept form:

m - slope
b - y-intercept → (0, b)
We have the points (-4, -6) and (2, 6). Substitute:

Put the coordinates of the point (2, 6) to the equation of a line:

<h3>Answer: y = 2x + 2</h3>
1. 5 -4x =6 +2x
+4x. +4x
5=6. +6x
-6 -6
-1 = 6x
--- ---
6. 6
-6=x
2. 9 - 2x = 7x
+2x. +2x
9 = 9x
--- ----
9. 9
1 = x
Answer:
Step-by-step explanation:
A) We use this relation: Distance = time * speed ( speed or vitesse or rate)
So d= 3.4*t= 3.4t (miles)
B) If t= 5/8
then the distance d= 3.4* 5/8= 2.125 miles.
C) If the distance d= 5.44, we can find the time like:
d= 3.4*t, and we know d=5.44
so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours
Hope you understand it.
