How do you convert 5y-x+4=0 into y=mx+b form?

1 answer:

3 0

$5y-x+4=0$

~Add x to both sides

$5y+4=x$

~Subtract 4 from both sides

$5y=x-4$

~Divide both sides by 5

$\frac{5}{5}y= \frac{1x}{5} - \frac{4}{5}$

~Simplify

$y= \frac{1}{5} x- \frac{4}{5}$

~M= $\frac{1}{5}$

~B= $-\frac{4}{5}$

3x + ky = 8

sattari [20]

Answer:

(a): x is 3 and ky is -1

(b): k is -2

Step-by-step explanation:

Let: 3x + ky = 8 be equation (a)

x - 2 ky = 5 be equation (b)

Then multiply equation (a) by 2:

→ 6x + 2ky = 16, let it be equation (c)

Then equation (c) + equation (b):

${ \sf{(6 + 1)x + (2 - 2)ky = (16 + 5)}} \\ { \sf{7x = 21}} \\ { \sf{x = 3}}$

Then ky :

${ \sf{2ky = 3 - 5}} \\ { \sf{ky = - 1}}$

${ \bf{y = \frac{1}{2} }} \\ { \sf{ky = - 1}} \\ { \sf{k = - 2}}$

Can someone answer this question and give an explanation

Temka [501]

Answer:

48cm^2

Step-by-step explanation:

First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.

After that, all you need to do it multiply and then add.

4*9 is 36, and 6*2 is 12.

36+12=48

Hope this helped!
