Five more than the product of a number and 8 equals 3 Use y for the unknown variable
Answers
Answer
y = -1/4
Step-by-step explanation:
Let the unknown variable be y
5 more than the product of a number and 8 equals to 3 can be expressed mathematically as
Recall, that the unknown variable is y
5 + (8 * y) = 3
Open the parenthesis
5 + 8y = 3
Substract 5 from both sides
5 - 5 + 8y = 3 - 5
8y = -2
y = -2/8
y = -1/4

Which of the following is a true stateme 3/4 < 4/6; 5/6 > 10/12; 8/16 = 1/4; 11/15 < 4/5
Answers
Answer:
11/15 < 4/5
Step-by-step explanation:
this is because:
3/4 < 4/6 is the same as 9/12 < 8/12 which is incorrect
5/6 > 10/12 is the same as 10/12 > 10/12 which is incorrect
8/16 = 1/4 is the same as 8/16 = 4/16 which is incorrect
therefore the only possible answer is 11/15 < 4/15 because:

Answers
Answer
Perimeter = 22 units
Explanation
To answer this, we need to note that two tangents to a circle that start from the same point usually have the same lengths.
So,
AD = AE = 6
CD = CF = 4
Since,
AB = 7 and AB = AE + EB
AE = 6
So,
AB = AE + EB
7 = 6 + EB
EB = 7 - 6
EB = 1
FB = EB = 1
So,
AC = AD + DC = 6 + 4 = 10
AB = 7
CB = CF + FB = 4 + 1 = 5
So, the perimeter of the triangle is given as the sum of all its exterior sides
Perimeter = AB + AC + CB
Perimeter = 7 + 10 + 5 = 22 units

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 .
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
-8 (-3

14. ∠FGB and ∠CHE are alternate exterior angles.
15. ∠CHG and ∠DHE are vertically opposite angles.
How to find angles?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles, linear angles etc.
The parallel lines are line AB and CD.
The transversal line is FE.
Therefore,
∠AGH is congruent to ∠DHG because they are alternate interior angles.
Alternate interior angles are congruent.
∠FGB is congruent to ∠CHE because they are alternate exterior angles.
Alternate exterior angles are congruent.
∠CHG is congruent to ∠DHE because they are vertically opposite angles.
Vertically opposite angles are congruent.

3x( 4x +7 ) + 3( 8 + 2 ) = 11( 2x + 3 ) + 11
?
Answers
Answer:
[tex]x=\dfrac{1 +\sqrt{673}}{24}, \quad x=\dfrac{1 -\sqrt{673}}{24}[/tex]
Step-by-step explanation:
Given equation:
[tex]3x( 4x +7 ) + 3( 8 + 2 ) = 11( 2x + 3 ) + 11[/tex]
Distribute the parentheses:
[tex]\implies 12x^2+21x+24+6=22x+33+11[/tex]
[tex]\implies 12x^2+21x+30=22x+44[/tex]
Subtract 22x from both sides:
[tex]\implies 12x^2+21x+30-22x=22x+44-22x[/tex]
[tex]\implies 12x^2-x+30=44[/tex]
Subtract 44 from both sides:
[tex]\implies 12x^2-x+30-44=44-44[/tex]
[tex]\implies 12x^2-x-14=0[/tex]
Use the quadratic formula to solve for x.
Quadratic Formula
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\quad\textsf{when }\:ax^2+bx+c=0[/tex]
[tex]\implies a=12, \quad b=-1, \quad c=-14[/tex]
Therefore:
[tex]\implies x=\dfrac{-(-1) \pm \sqrt{(-1)^2-4(12)(-14)}}{2(12)}[/tex]
[tex]\implies x=\dfrac{1 \pm \sqrt{1+673}}{24}[/tex]
[tex]\implies x=\dfrac{1 \pm \sqrt{673}}{24}[/tex]
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:
