The point (-2, k) lies on the line 2x – 4y + 3 = 0.<br> Find the value of k.

Over [174]

Answer:

k = (-1/4)

Step-by-step explanation:

Given that,

The point (-2, k) lies on the line 2x – 4y + 3 = 0.

We need to find the value of k.

Put x = -2 and y = k in the given equation.

2(-2) – 4k + 3 = 0

-4-4k = -3

-4+3 = 4k

-1 = 4k

k = (-1/4)

So, the value of k is equal to (-1/4).

Who can finish this for me

Paladinen [302]

Answer:

Step-by-step explanation:

$(5 - 5 {x}^{4} - {x}^{3} ) - (6 {x}^{3} - 4 {x}^{4} - 3)$

Remove unnecessary parentheses

$5 - 5 {x}^{4} - {x}^{3} - (6 {x}^{3} - 4 {x}^{4} - 3)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

$5 - 5 {x}^{4} - {x}^{3} - 6 {x}^{3} + 4 {x}^{4} + 3$

Collect like terms

$5 + 3 - 5 {x}^{4} + 4 {x}^{4} - {x}^{3} - 6 {x}^{3}$

$5 + 3 - {x}^{4} - 7 {x}^{3}$

Add the numbers

$8 - {x}^{4} - 7 {x}^{3}$

Use the commutative property to reorder the terms

$- {x}^{4} - 7 {x}^{3} + 8$

Hope this helps...

True or False. Is (3,1) a solution to this system:

Alisiya [41]

It would be false since none of them are equal to 1.
