Determine the check digit (d) for the UPC bar code number 2-91273-05213-d. Show your work?
Answers
the given UPC bar code digit is
2- 91273 - 05213 - d
for determining d we will follow the rule
first, we sum up all the odd place numbers
like
2 + 1 + 7 + 0 +2 + 3 = 15
then multiply with 3
15 * 3 = 45
then
we sum up all the even place numbers,
9 + 2 + 9 +5 + 1 = 26
now we will add these two results
26 + 45 = 71
now we can see that 71 is 9 less than the next multiple of 10 that is 80 in this case'
80 - 71 = 9
so the answer is
d = 9 .

Fill in the boxes with numbers and operations to reflect the equation of the circle after the transformations
Answers
Given the equation of the circle:
[tex]x^2+4x+y^2-12y=-24[/tex]We will complete the squares for x and y to write the equation of the circle as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]Where (h,k) is the coordinates of the circle and r is the radius of the circle
so, the equation will be:
[tex]\begin{gathered} (x^2+4x+4)+(y^2-12y+36)=-24+4+36 \\ \\ (x+2)^2+(y-6)^2=16 \\ \\ (x+2)^2+(y-6)^2=4^2 \end{gathered}[/tex]So, the radius of the circle = 4
And the center of the circle = ( -2, 6 )
Now, we will make the transformation for the circle:
Shift 1 unit up, the center will be = ( -2, 7 )
shift 2 units right, the center will be = ( 0, 7 )
Reflection across the x-axis, the center will be = ( 0, -7)
So, the equation of the circle after transformation will be:
[tex](x-0)^2+(y+7)^2=4^2[/tex]So, the answer will be:

So,
[tex]\begin{gathered} \text{diameter}=4\text{ inches} \\ \text{radius}=\frac{dameter}{2} \\ \text{radius}=\frac{4}{2} \\ \text{radius}=2 \end{gathered}[/tex]Then,

4) How many solutions does the system of linearequations have?2x + 3y = 6-8x - 12y = -20image
Answers
Answer
Explanation
To know how many solutions this system of linear equations have, we willl need to solve it.
2x + 3y = 6
-8x - 12y = -20
Making x the subject of formula in the first equation
2x + 3y = 6
2x = -3y + 6
Divide through by 2
(2x/2) = (-3y/2) + (6/2)
x = (-3y/2) + 3
Substituting this for x in the second equation
-8x - 12y = -20
x = (-3y/2) + 3

What is Algebra?
One of the many different mathematical disciplines is algebra. Algebra, a common thread that runs through nearly all of mathematics, is the study of mathematical symbols and the rules for using them in formulas.
To feed his plants, Miguel combines water and plant food. According to the directions on the plant food, you should add 1 teaspoon to every 4 cups of water. To demonstrate the relationship between cups of water (w) and teaspoons of plant food (f), create an equation.
48 teaspoons = 1 cup.
1 teaspoon = plants food
4 cups = water.
= 48 teaspoons x 4.
= 192 teaspoons
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
The mixture = 192w + f
The relation between f and w is f = kw.
1 teaspoon = plant food
7 cups = water.
= 48teaspoon x 7
= 336teaspoon
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
The mixture = 336w + f
Hence, 336 plant food should Miguel add to 7 cups of work
