The first 9 positive odd integers are placed in the following 3 by 3 grid in such a way that the sum of the numbers in each row, column, and main diagonal is the same. Four of the numbers are shown and the other five numbers are represented by the letters A, B, C, D, and E.
Determine the values of A, B, C, D, and E.
Answers
Answer:
As stated in the question, the 9 numbers in the boxes are 1,3,5,7,9,11,13,15,17. Now, I have to find clues to see how to figure out each number.
First clue: Looking at the first row and the right column, they both have the letter B in it, but the first row also has A. Since they both have B, A+1=13+3. Simplified, A = 15. So, I have figured out the first value.
Second Clue: I can see that B,C, and D all have a relationship. Because for B, the rows and columns add up to 16 only, but for C, the middle row adds up to 18. Therefore, the value of B must be 2 more than C. For the leftmost column, I can see that the other two numbers would add to 20, and middle row would only add up to 18. This shows that C is 2 more than D.
Using this information, I can find all their values since I know the 9 numbers that are supposed to be in each box. To figure out their values, I have to find three consecutive odd numbers.
The only numbers I have left are 7,9,11, and 17.
Now I know that D=7, C=9, and B=11.
All that is left is the number 17, and the letter E.
E=17.
According to the question, I have to find the value of A+E.
Since A=15, and E=17, 15+17=32.
The value of A+E=32.

How many solutions does the system of equations below have?
y = 3x + 4
y+ 6 = 3x
O A. Exactly 1 solution
O B. More than 1 solution
O C. At least 1 solution
O D. No solution
Answers
Answer:
No solution
Step-by-step explanation:
Let's solve your system by substitution.
y=3x+4;y+6=3x
Step: Solvey=3x+4for y:
y=3x+4
Step: Substitute3x+4foryiny+6=3x:
y+6=3x
3x+4+6=3x
3x+10=3x(Simplify both sides of the equation)
3x+10+−3x=3x+−3x(Add -3x to both sides)
10=0
10+−10=0+−10(Add -10 to both sides)
0=−10

In Mr. Kagame's Algebra 1 class, 7 students took the Unit 7 test. The class average was 78% (rounded). Six students' scores are known:HELPPP
Answers
The score of the seventh student will be given by:
[tex]x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
What is the score of the last student?
So you know the scores of 6 of the students, let's define these as:
a₁, a₂, a₃, a₄, a₅, a₆.
And let's define x as the score of the 7th student.
We know that the average of the scores is 78% (rounded).
Then we can estimate the value of x using the average equation:
[tex]\frac{a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + x}{7} = 78[/tex]
Now you can solve that for x, to get:
[tex]x = 78*7 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6\\\\x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
That is the equation to get the score of the seventh student as a function of the six known scores.

again we have 4/9 and we see what we can put in to get another 36 , but we have a 9, so it’s 4. 4/9 x 4/4 = 16/36 when you divide this you them both you get 0.44 so they’re equivalent.
so 0.25 is less than 0.44
basically it’s saying 25<44
so 1/4 is less than 4/9
Find all real solutions Tan pi/3 x-3=0
Answers
Step-by-step explanation:
If the question is like this,
[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]
We take the arc tan of both sides.
[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]
[tex] \frac{\pi}{3} x - 3 = 0[/tex]
[tex] \frac{\pi}{3} x = 3[/tex]
[tex] = \frac{9}{\pi} [/tex]
Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable
[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]
So the answer is
[tex] \frac{9}{\pi} + 3n[/tex]
If this the question,
[tex] \tan( \frac{\pi}{3} x) = 3[/tex]
[tex] \frac{\pi}{3} x = 1.249[/tex]
[tex]x = \frac{3.747}{\pi} [/tex]
The period is once again 3 so we have
[tex] \frac{3.747}{\pi} + 3n[/tex]

Suppose the distributor charges the artist a $50.00 cost for distribution, and the streaming services pay $ 5.00 per unit. (Note: One unit = one thousand streams) Model the profit for the total number of streams by answering the questions below:
1. Use the cost for distribution to build the y-intercept. What is the y-intercept?
Hint: the y-intercept is a point on the y axis, so the answer should be an ordered pair
(x,y). Keep in mind that money is being spent, and therefore must be deducted from the profit. If the y-intercept is incorrect, all related numbers will be incorrect.)
2. Use the payment per unit to build the slope. What is the slope?
Answers
Equation in slope intercept form
y=mx+by=5x+50Slope:-m=5
Y intercept=b=50
The y-intercept of the function is (0, 50) and the slope of the function is 5
How to calculate the slope and y-intercept of a function?Slope is defined as the rate of change of function. Given the following parameters
Fixed price = $50
If the streaming services pay $ 5.00 per unit, then the rate of change is $5
The required profit for the total number of streams is given as:
P(x) = 50 + 5x
1) The y-intercept is the point where the value of x is zero
P(x) = 50 + 5x
P(0) = 50 + 5(0)
P(0) = 50
Hence the y-intercept of the function is (0, 50)
For the slope
mx = 5x
m = 5
Hence the slope of the function is 5

What single percentage change is equivalent to a 9% increase followed by a 17% increase?
Answers
Answer:
27.53%
Step-by-step explanation:
Initial number = 100
9% increase
100*1.09= 109
17% increase
109*1.17= 127.53
The difference with the initial number is:
127.53 - 100 = 27.53
27.53/100*100% = 27.53%
