To get from 3x + 2y + 1 to -2x + y - 5, we need to subtract 5x + y + 6.
To determine what should be subtracted from 3x + 2y + 1 to get -2x + y - 5, we need to subtract the given expression from the desired result.
The given expression is -2x + y - 5.
So, the subtraction would be:
(-2x + y - 5) - (3x + 2y + 1)
To subtract these expressions, we distribute the negative sign to each term inside the parentheses:
-2x + y - 5 - 3x - 2y - 1
Next, we can combine like terms:
(-2x - 3x) + (y - 2y) + (-5 - 1)
Simplifying further:
-5x - y - 6
To get from 3x + 2y + 1 to -2x + y - 5, we need to subtract 5x + y + 6.

An irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.
Answer:
X = 109
Step-by-step explanation:
I = 5 – 2 (180) = 540
100 + 102 + 108 + 121 = 431
540 – 431 = 109
X= 109
The value of the angle x will be 109 degrees.
What are polygons?A polygon is a closed polygonal chain made up of a finite number of straight-line segments that are joined to form a planar figure in a geometry or polygonal circuit. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.
Given that an irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.
The value of the angle x will be calculated as below:-

Franklin loves to cook with fresh herbs. So, he decides to plant 8 different herbs and keep the small pots on his kitchen windowsill. He starts with a 4-pound bag of soil and puts the same amount of soil in each pot. If he uses all of the soil, how many ounces does he add to each pot?
Answer:
8 ounces for each pot
Step-by-step explanation:
First, we know there are 16 oz in a pound. Since there are 4 pounds, we multiply 4 by 16 to get 64, which is the amount of oz of dirt Franklin will plant. We then divide 64 by 8, to find out the amount of oz per pot.

a. The final result is -45 + ?(-3).
b. We have a negative value inside the square root, this expression is not defined in the real number system. If you're working with complex numbers, we can proceed by evaluating the square root of -130.
c. The result is 10.
d. The result is 6.
a. -15 × (-3 + 5) - 15 + ?(-3)
Let's simplify the expression step by step:
-15 × (-3 + 5) - 15 + ?(-3)
First, we can simplify the expression within the parentheses:
-15 × 2 - 15 + ?(-3)
Next, we perform the multiplication and addition:
-30 - 15 + ?(-3)
Now, let's address the "?(-3)" part. Since we don't have a specific value for the missing factor, we'll leave it as it is for now.
-30 - 15 + ?(-3)
Finally, we can simplify the expression by performing the subtraction:
-45 + ?(-3)
The final result is -45 + ?(-3).
b. √(-125 - 5) × 3²
Let's simplify this expression step by step:
√(-125 - 5) × 3²
First, we evaluate the expression within the square root:
√(-130) × 3²
Since we have a negative value inside the square root, this expression is not defined in the real number system. If you're working with complex numbers, we can proceed by evaluating the square root of -130.
c. (-5) - (-8) - (-7)
Let's simplify this expression step by step:
(-5) - (-8) - (-7)
To simplify double negatives, we can rewrite the expression as addition:
(-5) + 8 + 7
Now, we can perform the addition:
-5 + 8 + 7 = 3 + 7 = 10
The result is 10.
d. (-5) - (-8) - (-7) - (+2) - (+2)
Let's simplify this expression step by step:
(-5) - (-8) - (-7) - (+2) - (+2)
Again, let's rewrite the double negatives as addition:
(-5) + 8 + 7 - 2 - 2
Now, we can perform the addition and subtraction:
-5 + 8 + 7 - 2 - 2 = 3 + 7 - 2 - 2 = 10 - 4 = 6
The result is 6.

Answer: The slope is 2/3
Step-by-step explanation:
The difference in the rise (y-values) 2, divided by the difference in the run (x-values) 3, is 2/3.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (0, -1)
1 -(-1) ÷ 3 - 0
2 ÷ 3
2/3
The slope of the given line is 2/3.
From the given figure, the coordinates of the points on line are (3, 1) and (-3, -3).
What is slope of a line?The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.
The slope of a line is m=(y2-y1)/(x2-x1)
Using the coordinates (x1, y1) = (3, 1) and (x2, (y2) = (-3, -3)
Slope(m) = (-3-1)/(-3-3)
= -4/(-6)
= 2/3
Therefore, the slope of the given line is 2/3.

The total amount that Portfolio 2 earns is approximately $567.75.
How much does Portfolio 2 earn?To calculate the earnings for Portfolio 2, we need to calculate the return on each investment and then sum them up.
Return on Savings Account:
= $1,450 * 2.80%
= $40.60
Return on Government Bond:
= $2,200 * (-1.55%)
= -$34.10
Return on Preferred Stock:
= $3,700 * 11.70%
= $432.90
Return on Common Stock:
= $1,500 * 8.49%
= $127.35
Total earnings for Portfolio 2 is:

Find a and b using the factor theorem.
[tex]f(x)=x^3+ax^2+bx-12[/tex] has factor [tex](x-1), (x+1)[/tex]
The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.
To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

Answer:
See attached image
Step-by-step explanation:
In order to graph, find about three different points that belong to the line, and join them with a straight line.
The points I suggest are using easy values of "x" that will make the calculation of the y-value simple. For example the x-values: 0, 5, -5
When x = 0 , y becomes: y = -(2/5) (0) + 5 = 5
When x = 5, y becomes : y = -(2/5) (5) + 5 = - 2 + 5 = 3
When x = -5, y becomes: y = -(2/5) (-5) + 5 = 2 + 5 = 7
Then plot the points (0, 5), (5, 3) and (-5, 7) on the plane, and join them with a line as shown in the attached image.

h number of hours traveled by Joe
Speed is a physical quantity defined as the distance divided by time taken.
It is mathematically expressed as;
Speed = [tex]\frac{Distance}{time taken}[/tex]
Now substitute D for distance and h for the number time;
Speed = [tex]\frac{D}{h}[/tex]
