Step-by-step explanation:
A bedroom wall is 12 feet long. A decorator places the center of a square painting that has side lengths of 3 feet in the exact center of the bedroom wall.
How many feet are between the right edge of the painting and the right edge of the bedroom wall, x?
O 16 feet
o 9 feet
04 feet
.3 feet
the answer is 9 feet
cuz 12-3=9
What is the equation of a line parallel to 2x−3y=5 that passes through the point (−9,2)?
3x−2y=−31
3x+2y=−23
2x−3y=−24
2x+3y=−12
Parallel lines have the same slope
The equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]
From the question, we have:
[tex]\mathbf{2x - 3y = 5}[/tex]
Make y the subject
[tex]\mathbf{- 3y = 5 - 2x}[/tex]
Divide through by -3
[tex]\mathbf{y = \frac 23 x - 5}[/tex]
Because the required equation is parallel to [tex]\mathbf{2x - 3y = 5}[/tex], then they must have the same slope
A linear equation is represented as:
[tex]\mathbf{y=mx + c}[/tex]
Where:
m represents the slope
So, by comparison:
[tex]\mathbf{m = \frac 23}[/tex]
This means that:
The required equation has a slope of 2/3
The equation of the line is:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
Where:
[tex]\mathbf{m = \frac 23}[/tex]
[tex]\mathbf{(x_1,y_1) = (-9,2)}[/tex]
So, we have:
[tex]\mathbf{y = \frac 23(x + 9) + 2}[/tex]
Open brackets
[tex]\mathbf{y = \frac 23x + 6 + 2}[/tex]
[tex]\mathbf{y = \frac 23x + 8}[/tex]
Hence, the equation of the line is: [tex]\mathbf{y = \frac 23x + 8}[/tex]

g(x) = x^3+ x
. If
f(x) = g^-1(x)
and
f(2) = 1
what is the value of
f'(2)
?
Given that
[tex]g(x) = x^3 + x[/tex]
the inverse [tex]g^{-1}(x)[/tex] is such that
[tex]g\left(g^{-1}(x)\right) = g^{-1}(x)^3 + g^{-1}(x) = x[/tex]
or
[tex]g\left(f(x)\right) = f(x)^3 + f(x) = x[/tex]
Differentiating both sides using the chain rule gives
[tex]3f(x)^2f'(x) + f'(x) = 1 \\\\ f'(x) \left(3f(x)^2+1\right) = 1 \\\\ f'(x) = \dfrac1{3f(x)^2+1}[/tex]
Then the derivative of f at 2 is
[tex]f'(2) = \dfrac1{3f(2)^2+1} = \boxed{\dfrac14}[/tex]

Step-by-step explanation:
K12 test
figure has two intersecting lines and a ray.
From this figure, the value of x= 24
Given :
Two intersecting lines and a ray. one angle is 110 degrees.
opposite to 111 degrees are 87 and x degrees
From the two intersecting lines, we know that vertical opposite angles are equal .
111 degrees and 87+x are vertical opposite angles
So, they are equal .
Lets make them equal and solve for x
[tex]111=87+x[/tex]
Now we subtract 87 on both sides and solve for x
[tex]111-87=87-87+x\\\\x=24[/tex]
So the value of x is 24 degrees

Answer:
465 I think is the answer
% / 100 = Part / Whole
replace the given values:
85 / 100 = Part / 620
Cross multiply:
= 85 x 620 = 100 x Part
= 52700 = 100 x Part
Now, divide by 100 and get the answer:
Part = 52700 / 100 = 527

2: 4,000 composite units
Step-by-step explanation:
We assume your "composite unit" consists of the smallest set of units in the ratio in which they are sold.
1)A "composite unit" is 1B +2A. The contribution margins are the difference between the selling price and the variable cost per unit:
A: 72 -40 = 32
B: 48 -28 = 20
composite unit: 2A+B = 2(32) +20 = 84
(a) The contribution margin per composite unit is $84.
__
(b) The break-even point is the number of composite units that have a total contribution margin equal to the total fixed costs:
84n = 1260000
n = 1260000/84 = 15000
30,000 units of A and 15,000 units of B must be sold to break even.
__
(c) The additional number of composite units required to achieve pre-tax income of 294000 is ...
294,000/84 = 3500
37,000 units of A and 18,500 units of B must be sold for a pretax income of $294,000.
__
2)Contribution margins per unit are ...
H: 6 -4 = 2
C: 8 -6 = 2
I: 10 -7 = 3
A composite unit is 3H +2C +I, so the contribution margin per composite unit is ...
3(2) +2(2) +1(3) = 6 +4 +3 = 13 . . . dollars
The break-even point is 52,000/13 = 4,000 composite units

Answer:
a straight line has an angle of 180
therefore 180-109=71
71÷2 = 35.5
x is 35.5 degrees
The measure of x is 29 degree.
What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.As, Parallel line have property
Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.As, <CBA = <BAD (Alternate Interior Angle)
So, <BAD = 42
Now, <BAD + <BAC + <CAE = 180 (Linear Pair)
42 + 109 + x = 180
151 +x = 180
x = 180- 151
x = 29

Answer:
y=-2/5x-1
Step-by-step explanation:
I started by looking for the y-intercept of the line, where the line intersects with the y-axis and saw it was -1.
Then I looked at the slope of the line and used the rise/run strategy. From the y-intercept to the point it was 2 units down and 5 units across (2/5) and since it is going down it's negative
Plugging it in: y=mx+b
m=slope
b=y-intercept
y=-2/5x-1
Hope this helps :)
