Answer:
x = - 16
Step-by-step explanation:
The equation relating two proportional quantities is
y = kx ← k is the constant of proportionality
To find k use the condition when y = 1, x = - 4
k = 
= - 
y = - x ← equation of proportionality
when y = 4, then
4 = - x (multiply both sides by - 4 )
x = - 16
Answer:
v= 2
Step-by-step explanation:
The minutes taken by Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.
<h3>What is division?</h3>
It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
Grayson can text 70 words in 4 minutes,
The time is taken to type one word = 4 / 70 = 0.057 min
Thus, typing 140 words Grayson would take = 0.057 × 140 = 8 min
Therefore, the minutes taken Grayson to text 140 words if Grayson can text 70 words in 4 minutes is 8 min.

Whats the total perimeter?
For this case we have the following expressions:
So:
Indicates all values less than or equal to -2.
That is, from -∞ to -2.
Indicates all values greater than or equal to 0.
That is, from 0 to ∞.
The "or" means that they do not intersect. So, the correct graph is option A.
Answer:
Option A
