The table that represents a proportional relationship is:
x = -1, -3, -5
y = 1, 3, 5
<h3>
Which table represents a proportional relation?</h3>
A proportional relationship is written as:
y = k*x
Where k is the constant of proportionality.
Notice that for equidistant increases in x, we should have equidistant increases on y. Also, proportional relations always have the point (0, 0)
Then the table that represents a proportional relationship is:
x = -1, -3, -5
y = 1, 3, 5
Where the proportional relation is:
y = (-1)*x
When x = -1
y = (-1)*(-1) = 1
When x = -3
y = (-1)*-3 = 3
When x = -5
y = (-1)*(-5) = 5
So the correct option is the second one.

The correct answer is: x ≥1
Answer:
Eight times ten plus six times one plus two times one-tenth plus seven times one-thousandth.
Step-by-step explanation:
(8 x 10) = eight times ten
(6 x 1) = six times one
(2 x 0.1) = two times one-tenth
(7 x 0.001) = seven times one-thousandth
I am not always the best with the equations to words stuff, so please comment if I am wrong!
Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
