How do I graph y+x= -3

Nitella [24]

Answer:

Use Desmos.com/calculator

Step-by-step explanation:

Remember, y=mx+b

y is equal to any given y point

x is equal to any given x point

m is equal to slope

b is equal to the y-intercept, or where x = 0 and the line crosses the horizon line.

In order to graph the line correctly, you have to isolate y.

y+x=-3

y=-x-3 would be equal to y=mx+b format

slope is negative 1

y intercept is negative 3

start on the y line, go to (0,-3) and start your line.

slope is negative 1, so you go down one and right one.

kap26 [50]

Answer:

-60% decrease

Step-by-step explanation:

60 is the old value and 24 is the new value.

percent change = $\frac{new - old}{|old|}$ x 100%

so for this problem, you can substitute the values given in the formula:

percent change = $\frac{60-24}{|60|}$ x 100% = $\frac{-36}{60}$ x 100% =

Solve c =(a² + 3b)/4 for b. Bruv take all my points I literally blow at math :'(

Sati [7]

Answer:

$b=\frac{4c-a^{2} }{3}$

Step-by-step explanation:

First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division

Then, you have $4c=a^{2} +3b$

Subtract both sides by a squared

DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition

From that you get $4c-a^{2} =3b$

Finally, divide both sides by 3.

You get $b=\frac{4c-a^{2} }{3}$
