Second month=$35
Third month=$45
Fourth month=$55
Fifth month=$65
Sixth month=$75
Seventh month=$85
Eighth month =$95

Answer:
70 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
x + 65 + 45 = 180
x + 110 = 180
x = 180 - 110
x = 70
The size of angle x is 70 degrees.
Answer:
70
Step-by-step explanation:
180-65-45=70
Good luck

y=-4x-5 y=3x-2 is (3,7) a solution of the system?
Answer:
No
Step-by-step explanation:
Does (3, 7) satisfy the first equation, y = -4x - 5? Is 7 = -4(3) - 5 true? NO. Thus, (3, 7) cannot be a solution of the system
y=-4x-5
y=3x-2
The given point (3, 7) is not the solution in the given case.
What is a system of linear equations?A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
Given equations are as follows,
y = -4x - 5 (1)
y = 3x - 2 (2)
In order to find whether (3,7) is the solution for them, substitute x = 3 and y = 7 in both the equations and check the LHS and RHS of both.
For equation (1),
y = -4x - 5
LHS is y = 7
RHS = -4x - 5
= -4 × 3 - 5
= -17
Since, LHS ≠ RHS, the given values of x and y are not the solution for the given equation.
Now, equation(2) need not to be checked as the result for the given values is already not valid for equation(1).
Hence, the given coordinate (3,7) is not the solution for the given equations.

Four ounces of oregano and 2 ounces of garlic powder are mixed to create a poultry seasoning. Oregano costs $4 per ounce and garlic powder costs $3 per ounce. The table shows the costs of the ingredients.What is the value of y in the table?
There isn't an obvious question to this problem but with the given we can assume what is to be asked. I think we are to find the total cost of a certain poultry seasoning. The poultry seasoning would have a total weight of 4+2=6 ounces. The total cost will then have to be 4(4) + 2(3) = 22 dollars.

Answer:
f = 4
Step-by-step explanation:
Step 1: Distribute
-11f = 7 - 14f + 5
Step 2: Combine like terms
-11f = 12 - 14f
Step 3: Add 14f to both sides
3f = 12
Step 4: Divide both sides by 3
f = 4
Answer:
F = 4

Which of the following expressions is not equal to the others? 4ax2y 8ax y 2ayx4a ax 8y
Answer: 2ayx4a
Step-by-step explanation:
1) First, we will need to simplify each equation:
4ax2y = 8axy
8axy = 8axy
2ayx4a = 8ayx4a
ax8y = 8axy
2) We can now see that 2ayx4a is not the same as the others.
Solve each system by the addition method.

Put your answer in ordered pair (x, y) form.
When solving a system by addition, our goal is to cancel out one of the variables by adding the two equations together.
Notice that if we add these two equations together,
neither one of our variables will cancel out.
In this situation, we need to set things up so that when we do add
our two equations together, one of our variables will cancel out.
Notice that we have a 2x in our first equation.
If we had a -2 in our second equation,
then the x's would cancel out.
In order to create a -2x in the second equation,
we simply multiply both sides of the second equation by -2.
So we have (-2)(x - 2y) = (10)(-2).
Rewriting both equations, we have 2x + 4y = 28 and for
our second equation we have -2x + 4y = -20.
Now when we add our two equations together,
our x terms will cancel out and were left with 8y = 8.
Dividing both sides by 8, y = 1.
To solve for x, substitute a 1 in for y
in either one of the two equations.
So let's go with our first equation.
If we substitute a 1 in for y, we have 2x + 4(1) = 28.
4(1) is 1 according to the identity property of multiplication.
So we have 2x + 4 = 28.
Now subtract 4 from both sides to get 2x = 24.
Now divide both sides by 2 and x = 12.
Now put your answer in the form of the ordered pair {12, 1}.
What is the domain of the function y= Vx+4

A rectangular piece of cardboard, 100 cm by 40 cm, is going to be used to
make a rectangular box with an open top by cutting congruent squares from
the corners. Calculate the dimensions (to one decimal place) for a box with
the largest volume.
Answer:
16,242. 7 cm^3.
Step-by-step explanation:
We need to cut off a square piece at the 4 corners of the cardboard.
Let the length of their edges be x cm.
The volume of the box will be:
V = height * width * length
V = x(100-2x)(40-2x)
V = x(4000 - 200x - 80x + 4x^2)
V = x(4x^2 - 280x + 4000)
V = 4x^3 + - 280x^2 + 4000x
Finding the derivative:
dV / dx = 12x^2 - 560x + 4000 = 0 ( when V is a maxm or minm.)
4(3x^2 - 140x + 1000) = 0
x = 37.86, 8.80.
Looks like x = 8.80 is the right value but we can check this out be looking at the sign of the second derivative:
V" = 24x - 560, when x = 8.8 V" is negative so this is a Maximum for V.
So the maximum volume of the box is when x = 8.8 so we have
V = 8.8(100-2(8.8)(40 - 2(8.8)
= 16,242. 7 cm^3.

Step-by-step explanation:
9(2x-7y)
= 9 * 2x - 9 * 7y

Hope this helps!
Answer:
Step-by-step explanation:
Distribute (multiply) the 9 to both the 2x and -7y
You get: 18x -63y
This is because 9 times 2x is 18x. Furthermore, 9 times -7y is equal to -63y

x=89°
Hey there! :)
Answer:
x = 89°.
Step-by-step explanation:
x + 42 is supplementary to the inside angle at the top of the triangle, so:
The top angle of the triangle is equal to:
180 - x - 42.
All of the angles in a triangle add up to 180°, therefore:
180 = x + x - 47 + 180 - x - 42
Combine like terms:
180 = 2x + 133 - x - 42
180 = x + 91
Subtract 91 from both sides:
89 = x.
Therefore, x = 89°.

Try to answer the following question without running the code in Python:
If we run the following program:
a = 2 + 6
b = 7 % 3
c = a - b
c = c * 5
print(c)
what gets printed?
Answer:
35
Step-by-step explanation:
Given
the above lines of code
Required
What's the output
We'll analyze the code line by line
a = 2 + 6
At this point a = 8
b = 7 % 3
At this point b = 1. This is so because, the remainder of 7%3 is 1
c = a - b
At this point c = 7;
This is calculated by c = 8 - 1 = 7
c = c * 5
At this point; c = 35
This is calculated by: c = 7 * 5 = 35
print(c)
The value of c, which is 35 is printed
Use the Distributive Property to write each expression as an equivalent algebraic expression. (7 + a)3 Question 4 options: 3(7a) 21 + 3a 10 + 3a 7 + 3a
Answer:
(B)21+3a
Step-by-step explanation:
An expression is said to be distributive when:
[tex](a+b)c=a \cdot c+b \cdot c[/tex]
Given the algebraic expression: (7 + a)3
Applying the distributive property
[tex](7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a[/tex]
An equivalent expression is 21+3a.
The correct option is B
two angles of a triangle measure 27 degrees and 17 degrees what is the measure of the third angle? A) 146 degrees B) 136 degrees C) 46 degrees D) 44 degrees
Answer:
The third angle is 136
Step-by-step explanation:
The three angles of a triangle add to 180
27+17+x = 170
Combine like terms
44+x = 180
Subtract 44 from each side
44+x-44 =180-44
x =136
Answer:
136° is the answer.
Step-by-step explanation:
given ,
1st angle=27°
2nd angle= 17°
let the third angle be x
then ,x+27°+17°=180°
or x+44°=180°
or, x=180_44
therefore the value of x is 136°.

Answer:
4th choice: I and IV only
Step-by-step explanation:
Change the form of the given equation to standard form.
y = -2/3 x + 2
3y = -2x + 6
2x + 3y = 6
Now compare this equation with the 4 choices.
Any equation that has the same x- and y-terms but a different constant term is parallel.
I. is parallel.
II. and III. are not parallel.
Look at IV.:
4x + 6y = 3
Divide both sides by 2:
2x + 3y = 3/2
IV. is also parallel.
Answer: 4th choice: I and IV only
Answer:
I and IV only
Step-by-step explanation:
In order for graphs to be parallel, they must have the same slope
In this case, we are looking for a slope of -2/3
We can find the other slopes by solving for y (y=mx+b)
I. 2x+3y=10
Subtract 2x from both sides
3y=-2x+10
Divide by 3
y=-2/3+10/3 This works since the slope is identical
II. 2x-3y=9
Follow a similar progression as the previous (subtract the x's and divide the y's)
-3y=-2x+9
y=2/3=3 This doesn't work since it is positive
III. 4x-6y=30
-6y=-4x+30
y=2/3 x-5 (4/6 simplified to 2/3) Also doesn't work since it is positive
IV. 4x+6y=3
6y=-4x+3
y=-2/3x+3 (-4/6 simplified to -2/3) This one works, it is identical
