3x + 2y = -9<br> 4x - 2y = -26<br> please help I have to solve this with the elimination method
Paladinen [302]

Answer:

x = - 5, y = 3

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 9 → (1)

4x - 2y = - 26 → (2)

Adding (1) and (2) term by term eliminates the y- term, that is

7x = - 35 ( divide both sides by 7 )

x = - 5

Substitute x = - 5 into either of the 2 equations and solve for y

Substituting into (1)

3(- 5) + 2y = - 9

- 15 + 2y = - 9 ( add 15 to both sides )

2y = 6 ( divide both sides by 2 )

y = 3

Having trouble with this one help appreciated
Hoochie [10]

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

y=kx

The number 'k' is called the constant of proportionality.

Given the equation

y=3.50x

as

y=kx

so

k=3.50           ∵ y=kx

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.
