what is 4 ( x+2 )=10
Answer:
x= 1/2
Step-by-step explanation:
We can use Distributive property to solve this.
4(x+2)=10
4x+8=10
-8 -8
4x= 2
4x/4= 2/4
x= 1/2
Hope this is right!
Answer: x = 2
Step-by-step explanation:
4(x+2)=10
4x + 8 =10
10 - 8 = 2
4x / 2 = 2
2 = x

The graph shows a function that models the value V (in millions of dollars) of
stock portfolio as a function of time t (in months) over an 18-month period.
Identify any extreme value of the function
Answer:
Option (B)
Step-by-step explanation:
A function that models the value V of the stock portfolio as function of t is given by the graph.
Each grid on the y - axis measures = [tex]\frac{3-2}{4}[/tex] = 0.25
Each grid on the x - axis measures = 1 unit
Local maximum from the graph = (3, 2.5)
Global minimum = (13, 0.75)
Global maximum = (18, 3)
Local minimum = (13, 0.75)
Here local and global minimum of the function will be same as (13, 0.75).
Therefore, Option (A) will be the answer.

find the slope of the line through each pair of points (-19,20) (20,7)
Answer:
m (slope) = 13/-39 (13 over -39)
Step-by-step explanation:
To find the slope by using two points, we do rise over run (y over x)
y2-y1 (the numbers 1 and two don't matter, it's just to be sure that each point's numbers line up, for example, that -19 and 20 line up, and that 20 and 7 line up)
x2-x1
20-7 = 13
-19-20 = -39
Then, simplify
13/-39 cannot be simplified, so that is your answer.

Answer:
x = -3
y = -2
z = 6
or

Step-by-step explanation:
So first, lets construct our matrix:
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\2&1&1&-2\\1&-1&3&17\end{array}\right][/tex]
Now lets get it into reduced row echelon form. R₂ ⇒ -2R₁ + R₂
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&-5&7&52\\1&-1&3&17\end{array}\right][/tex]
R₃ ⇒ -R₁ + R₃
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&-5&7&52\\0&-4&6&44\end{array}\right][/tex]
R₂ ⇒ -1/5R₂
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&1&-\frac{7}{5}&-\frac{52}{5}\\0&-4&6&44\end{array}\right][/tex]
R₃ ⇒ 4R₂ + R₃
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&1&-\frac{7}{5}&-\frac{52}{5}\\0&0&\frac{2}{5}&\frac{12}{5}\end{array}\right][/tex]
R₃ ⇒ 5/2R₃
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&1&-\frac{7}{5}&-\frac{52}{5}\\0&0&1&6\end{array}\right][/tex]
R₂ ⇒ 7/5R₃ + R₂
[tex]\left[\begin{array}{ccc|c}1&3&-3&-27\\0&1&0&-2\\0&0&1&6\end{array}\right][/tex]
R₁ ⇒ 3R₃ + R₁
[tex]\left[\begin{array}{ccc|c}1&3&0&-9\\0&1&0&-2\\0&0&1&6\end{array}\right][/tex]
R₁ ⇒ -3R₂ + R₁
[tex]\left[\begin{array}{ccc|c}1&0&0&-3\\0&1&0&-2\\0&0&1&6\end{array}\right][/tex]
And now we have our matrix in reduced row echelon form. The solution to the system of equations would be:
x = -3
y = -2
z = 6
(-3, -2, 6)
I hope you find my answer and explanation to be helpful. Happy studying.
The equation is reduced in an echelon form given below. Then the value of x, y, and z will be −3, −2, and 6.
[tex]\begin{bmatrix} 1 & 3 & - 3 & | & -27\\ 2 & 1 & 1 & | & -2 \\ 1 & -1& 3 & | & 17\\\end{bmatrix}[/tex]
What is the echelon form?When a matrix in a row image is transformed, Gaussian eradication has been applied to the rows, and when it is in a column image is transformed, Gaussian extinction has been applied to the sections. In other words, if a matrix's transposition is in row normalized form, the matrix is in pillar echelon form.
Let the equations be a₁x + b₁y + c₁z = d₁, a₂x + b₂y + c₂z = d₂, a₃x + b₃y + c₃z = d₃.
Then the echelon form is given as,
[tex]\begin{bmatrix}a_1 & b_1 & c_1 & | & d_1\\ a_2 & b_2 & c_2 & | & d_2\\ a_3 & b_3 & c_3 & | & d_3\\\end{bmatrix}[/tex]
The equations are given below.
x + 3y − 3z = − 27
2x + y + z = − 2
x − y + 3z = 17
Then the solution to the system of equations will be done using a calculator. Then the value of x, y, and z will be
x = -3, y = -2, and z = 6
The equation is reduced in an echelon form and will be
[tex]\begin{bmatrix} 1 & 3 & - 3 & | & -27\\ 2 & 1 & 1 & | & -2 \\ 1 & -1& 3 & | & 17\\\end{bmatrix}[/tex]

Given:
A,B, and N are collinear and AB+BN= AN.
To find:
The point which is between the other two points.
Solution:
If A,B, and N are collinear, then these three points must be lie a single straight line.
AB + BN = AN
It means, the segment AN is the addition of two small segments AB and BN.
Using segment addition property, it is possible it and only if point B lies between A and N.
Therefore, the point B lies between A and N.

What is the correct Unit Rate for 54 pints of juice in 3 containers? *
Answer:
0.0555 containers
Step-by-step explanation:
We need to find the unit rate for 54 pints of juice in 3 containers. It means we need to find quantity of juice in 1 container.
54 pints = 3 containers
1 pint = [tex]\dfrac{1}{18}\ \text{containers}[/tex]
or
1 pint = 0.0555 containers
So, unit rate is 0.0555 containers.

What is the remainder when you divide
(2x3 – 5x – 7) by (x + 2) ?
Answer :i think its -13
Step-by-step explanation:
Answer:
The remaider is (- 13)Step-by-step explanation:
If we divide W(x) by (x-a) then the remainder is W(a)
W(x) = 2x³ - 5x - 7
x - a = x + 2 ⇒ a = -2
W(-2) = 2(-2)^3 - 5(-2) - 7 = 2(-8) + 10 - 7 = -16 + 3 = -13

In each circle below, a 50° angle with a vertex at the center of the circle is drawn. How are minor arc lengths CD and EF
related?
A <
50
BF
50°
2 cm
cm
They are the same because the central angle measure is the same.
The arc lengths are proportional: CD = 2 EF
Answer:
C. The arc lengths are proportional: Arc C D = 4 arc E F.
Step-by-step explanation:
The question is incomplete. Here is the complete question.
In each circle below, a 50° angle with a vertex at the center of the circle is drawn. How are minor arc lengths CD and EF related?
Circle A and B are shown. Line segments D A and C A are radii with lengths of 8 centimeters. Angle D A C is 50 degrees. Line segments F B and E B are radii with lengths of 2 centimeters. Angle F B E is 50 degrees.
They are the same because the central angle measure is the same.
The arc lengths are proportional: Arc C D = 2 arc E F.
The arc lengths are proportional: Arc C D = 4 arc E F.
The arc lengths are proportional: Arc C D = 6 arc E F.
Using the formula for calculating the length of an arc to find the length of both arcs.
[tex]L = \frac{\theta}{360} * 2\pi r[/tex]
For the minor arc CD:
[tex]\theta = 50^0\\[/tex]
r = 8cm
L = 50/360 * 2π(8)
L = 5/36 * 16π
L = 80π/36
Length of CD = 20π/9 cm²
For the minor arc EF:
[tex]\theta = 50^0\\[/tex]
r = 2cm
L = 50/360 * 2π(2)
L = 5/36 * 4π
L = 20π/36
Length of arc EF = 5π/9 cm²
Find the relationship between both lengths:
From CD = 20π/9 cm²
CD = 4 * (5π/9 cm²)
since length of arc EF = 5π/9 cm²
Then arc CD = 4* arc EF
This shows that the length of arc CD is four times that of arc EF
