The equation is written in slope intercept form [ y = mx + b ]

m = slope

b = y-intercept

Using what I wrote above, we can see that:

m = 3

b = 30

Best of Luck!

Answer:

Solve y-3x+30 = 0

Step-by-step explanation:

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-3x+30 = 0 and calculate its properties

A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the price

sergejj [24]

We suggest, that the number 32 is 100% - because it is the output value of the task.
We suggest, that x is the value that we are looking for. 
3. If 32 is 100%, so we can jot it down as 32=100%. 
4. We know for sure, that x is 15% of the output value, so we can jot it down as x=15%. 
5. Now, these are the equations are we have.
1) 32=100%
2) x=15%
where the left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
32/x=100%/15%
6. Now we just have to work out the equation, and we'll get the answer that we want.

7. Answer for what is 15% of 32

32/x=100/15
(32/x)*x=(100/15)*x - multiply both sides of the equation by x
32=6.66666666667*x - divide both sides of the equation by (6.66666666667) to get x
32/6.66666666667=x 
4.8=x 
x=4.8

15% of 32=4.8
So, the answer is $4.8
Hope this helped

denis-greek [22]

A) I included a graph, look below.

B)

Input the y in x = y + 3.

x = (-4x - 3) + 3
x = -4x + 0
Add 4x to both sides.
5x = 0
Divide both sides by 5.
x = 0

Input that x value in y = -4x - 3

y = -4(0) - 3
y = 0 - 3
y = -3

(0, -3)

C)

Convert both equations to Standard Form.

x = y + 3
Subtract y from both sides.
x - y = 3

y = -4x - 3
Add 4x to both sides.
4x + y = -3

Add the equations together.

4x + y = -3
x - y = 3
equals
5x = 0
Divide both sides by 5.
x = 0

Input that into one of the original equations.

0 = y + 3
Subtract 3 from both sides.
-3 = y

(0, -3)

P(A) = .6, P(B) = .3, P(Β | A) = .5

Reika [66]

Answer:

Step-by-step explanation:

$P(B|A)=\frac{A ~and~B}{P(A)} \\0.5=\frac{P(A and B)}{0.6} \\P(A~and~B)=0.5 \times 0.6=0.30$
