Answer:
C
Step-by-step explanation:
a typical line equation is the slope-intercept form
y = ax + b
"a" is the slope (always the factor of x) expressed as ratio of "y coordinate difference" / "x coordinate difference".
b is the y-intercept (the y value when x = 0).
going from (-2, 5) to (0, 3) we see
x changes by +2 (from -2 to 0).
y changes by -2 (from 5 to 3).
so the slope is -2/+2 = -1
using one of the points (0, 3) to solve for the missing b :
3 = -1×0 + b
b = 3
so, the equation is
y = -x + 3
Answer:
The answer to your question is diagonal = 30 in, width = 24 in, height = 18 in.
Step-by-step explanation:
- From the data given, we conclude that the proportion 4:3 is 0.75.
So the 30-inch television must have the same proportion 4:3 or 0.75.
The dimensions of the new TV must be lower than 30.
Use proportion to solve this problem
5 : 4 :: 30 : x
x = (30 x 4) / 5
x = 24 in
And
5 : 3 :: 30 : x
x = (3 x 30) / 5
x = 18
The data given help to calculate the dimensions of the 30 in TV.

Answer:
a(t) = 700t-400
Step-by-step explanation:
Given that when Nour drove altitude increased at a constant rate. Let us consider sea level as 0 and starting time as 0 we have
At the start t =0 and a = -400 m
When t=2 a = 1000 m.
Rate of change of a wrt time = change in a/Change in time
= {1000-(-400)}/(2-0) = 700
i.e. slope = 700
a = 700 t +C
To find C:
When t =0, a =-400
Hence C =-400
Equation is a(t) = 700t-400
