Answer:
4.7= r/5
Step-by-step explanation:
Let the number of years of watching TV be
x
.
The number of years sleeping exceeds the number of years watching TV by
18
. This means that the number of years sleeping is higher than the number of years watching TV by
18
and can be represented by
（x+18).
The total time is 34
years. So we can form the following equation and solve for the required values:
x+(x+18)=34
x+x＋18=34
2x=34-18
2x=16
x=16/2
x=8
Thus, the number of years watching is 8
and the number of years sleeping is
8+18=26
.
Answer:
y = - 2x + 110
Step-by-step explanation:
The equation of a line in slope- intercept form is
y + mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 110) and (x₂, y₂ ) = (20, 70) ← 2 points on the line
m = 
= 
= - 2
the line crosses the y- axis at (0, 110) ⇒ c = 110
y = - 2x + 110 ← equation of line
Y = 1/(x - -2)
y = 1/(x + 2)
I moves the graph 2 units to the left
-8
On the number line if you are at positive 8 and add -8 you will lose 8 and get zero! Hope this helps!
