Find b if the equation is w=2a+3b

1 answer:

3 0

There isn't enough information to know the exact number of b but

w=2a+3b
subtract 2a from both sides
2a-w=3b
divide both sides by 3
$2a - w \div 3 = b$

PLEASE HELP!!! WILL MARK BRAINIEST

Serga [27]

y = -4x + 3 this line has slope = -4

parallel lines, slope is the same so slope of new line is also equal -4

passing thru (8, -3)

y = mx + b

b = y - mx

b = -3 - (-4)(8)

b = -3 + 32

b = 29

equation:

y = -4x + 29

hope it helps

Work out m and c for the line:<br> 2x + 3y +1=0 <br><br>m=<br>c =

Sergio [31]

Answer:

m = - $\frac{2}{3}$ , c = - $\frac{1}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 3y + 1 = 0 ( subtract 2x + 1 from both sides )

3y = - 2x - 1 ( divide terms by 3 )

y = - $\frac{2}{3}$ x - $\frac{1}{3}$ ← in slope- intercept form

with m = - $\frac{2}{3}$ and c = - $\frac{1}{3}$
