The equation of the line is “y = -x + 2”.

Answer:

y=-x+2

Step-by-step explanation:

To work out the equation for this line you would first need to find the formula for the direction of the line. This is because if the y axis was on 1 the x axis is on the negative of that number.Then as the line is deviated, so you would need to find by how much it has deviated. To find that out you would look at the y intercept and count how many squares it has moved by. This is because the formulas y=x and y=-x all cross through (0,0). If it has moved up from (0,0) then you would write it as + and the deviation, and if it is below you would write it as a -.

1) Find the formula for the direction of the diagonal line.

In this case it would be $y=-x$ .

2)Find by how much the line has deviated.

In this case it is +2

3) The formula for the line

$y=-x+2$

Only the top one is equivalent to c/(13a)

The rule is (a^b)/(a^c)=a^(b-c)

Expand and simplify x(x + 2)(x + 4)

Answer:

Step-by-step explanation:

Comment

Expand the second and 3rd factors first. Then worry about the x.

Solution

x(x + 2)(x + 4)

first: x * x = x^2

Outside: 4*x = 4x

Inside: 2*x = 2x

Last: 2*4 = 8

Combine

x^2 + 4x + 2x + 8

x^2 + 6x + 8

Now is the time to worry about the extra x

x(x^2 + 6x + 8)

remove the brackets.

x*x^2 + x*6x + 8*x

Combine

Answer: x^3 + 6x^2 + 8x

Cost of a CD: $23.50 Markup: 63% Discount: 50%

Vedmedyk [2.9K]

Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.
=
$
23.50
+
(
$
23.50
⋅
(
63
%
100
)
)
(we divide by 100 to get the number out of a percent)
=
$
23.50
+
(
$
23.50
⋅
0.63
)
=
$
23.50
+
$
14.81
=
$
38.31
Ok now that we have the number after the price increase, we now need to find the final answer after a discount of
50
%
(do the exact same idea as above but switch the sign)
=
$
38.31
−
(
$
38.31
⋅
(
50
%
100
)
)
=
$
38.31
−
(
$
38.31
⋅
0.5
)
=
$
38.31
−
$
19.16
=
$
19.15
