Answer:
y = [tex]\frac{4}{3}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
8x - 6y + 12 = 0 ( subtract 8x + 12 from both sides )
- 6y = - 8x - 12 ( divide terms by - 6
y = [tex]\frac{-8}{-6}[/tex] x + 2 , that is
y = [tex]\frac{4}{3}[/tex] x + 2 ← in slope- intercept form
Janet has a $65 budget to buy paper goods and plastic cutlery for an impromptu birthday party. She determines that the paper goods will cost $37.50. How many sets
of cutlery can she purchase if each set costs $0.75?
Janet can purchase 36.67 sets of cutlery if each set costs $0.75.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
Janet has $65 to spend on paper goods and cutlery, and the paper goods will cost $37.50,
So, she has $65 - $37.50 = $27.50 remaining to spend on cutlery.
Each set of cutlery costs $0.75,
So, Janet can purchase sets of cutlery :
⇒ $27.50 / $0.75
Apply the division operation, and we get
⇒ 36.67
Since it's not possible to buy a fraction of a set, Janet can only buy 36 sets of cutlery.
Therefore, she can purchase 36.67 sets of cutlery.

Answer:
3x^2 -2x + 1 =3(x^2-2/3x+1/3)=3(x-1/3)^2+2/9*3= 3(x-1/3)^2+2/3
(x-1/3)^2 is greater or equal to zero
3(x-1/3)^2 is greater or equal to zero
and 2/3 is greater than zero
So there sum is greater than zero
Proved
Step-by-step explanation:
3x^2 -2x + 1 =3(x^2-2/3x+1/3)
Consider x^2-2/3x+1/3
Remember that (a-b)^2 =a^2-2ab+b^2
x^2=a^2
a=x
-2/3x= -2*x*b
b=1/3
S0 (x-1/3)^2= x^2-2/3x+1/9
x^2-2/3x+1/3= x^2-2/3x+1/9+1/3-1/9= (x-1/3)^2+2/9
3x^2 -2x + 1 =3(x^2-2/3x+1/3)=3(x-1/3)^2+2/9*3= 3(x-1/3)^2+2/3
(x-1/3)^2 is greater or equal to zero
3(x-1/3)^2 is greater or equal to zero

The solution for s in the given equation is [tex]s = C-nD[/tex]
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation [tex]D= \frac{C-s}{n}[/tex] Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
[tex]D= \frac{C-s}{n}[/tex]
To solve for s, first multiply both sides by n to clear the fraction
We get
[tex]n\times D= n \times \frac{C-s}{n}[/tex]
Then,
[tex]nD = C - s[/tex]
Now, add s to both sides
[tex]nD + s= C - s+s[/tex]
[tex]nD+s = C[/tex]
Then, subtract nD from both sides
[tex]nD-nD+s = C-nD[/tex]
∴ [tex]s = C-nD[/tex]
Hence, the solution for s in the given equation is [tex]s = C-nD[/tex]

44 is the product 4 and Greg's height. Use the variable g to represent Greg's height
Step-by-step explanation:
do you happen to have a photo reference your sentence is a bit confusing
Answer:
44 = 4 · g OR g · 4 = 44
Step-by-step explanation:
So first we need to know what a variable is...
A variable is an unknown number in a math sentence
Knowing that we can write the equation.
"44 is the product 4 and Greg's height. Use the variable g to represent Greg's height"
Since we do not know Greg's height that is what we will use variable g to substitute it.
"44 is the product 4 and g"
Now all we have to do is convert this into an equation
(Note: Whenever you see product of something know that it means that you need to multiply)
So your final answer is...
44 = 4 · g
(Explanation: Since it says 44 is the product of then it means it is the answer so we will put an equal sign)

Find the coordinates of the point 7/10 of the way from A to B.
Answer:
The coordinates are (6.5, 1.7).
Step-by-step explanation:
The difference between A and B's x-coordinate is 15. 7/10 of this is 10.5, which added to -4 gives us an x-coordinate of 6.5.
The difference between A and B's y-coordinate is 11. 7/10 of this is 7.7, which added to -6 gives us a y-coordinate of 1.7.
Therefore, the coordinates are (6.5, 1.7).

One-sixth of the smallest of three consecutive even
integers is three less than one-tenth the sum of the
other even integers. Find the integers. this
#49 with work pleasee
Answer:
The three even, consecutive integers are 72, 74, and 76.
Step-by-step explanation:
Let a be the first even integer.
Then the other two consecutive integers, b and c, will be represented by:
[tex]\displaystyle b = a + 2 \text{ and } \\ \\ c = b + 2 = (a + 2) + 2 = a + 4[/tex]
One-sixth of the smallest (that is, a) is three less than one-tenth the sum of the other two even integers (that is, b and c).
Therefore:
[tex]\displaystyle \frac{1}{6} a = \frac{1}{10}\left( b +c\right) - 3[/tex]
Solve for a. Substitute:
[tex]\displaystyle \frac{1}{6} a =\frac{1}{10}\left((a+2)+(a+4)\right) - 3[/tex]
Simplify and solve for a:
[tex]\displaystyle \begin{aligned} \frac{1}{6} a &= \frac{1}{10}(2a + 6) - 3 \\ \\ \frac{1}{6} a &= \frac{1}{5} a + \frac{3}{5} - 3\\ \\ -\frac{1}{30} a &= -\frac{12}{5} \\ \\ a &= 72\end{aligned}[/tex]
Hence, the first even integer is 72.
Therefore, the two other consecutive even integers must be 74, and 76.
In conclusion, the three even, consecutive integers are 72, 74, and 76.
B is the midpoint of AC. If AB = x + 5 and AC = 3x - 6, find BC.
Hey there! I'm happy to help!
We see that at AB is halfway across our line. We see that AC is the total line.
So, to find the other half, we have to subtract AB from AC, which will give us the value of BC.
We first will subtract our x values.
3x-x=2x
And then we subtract our numbers.
-6-5=-11
So, BC is 2x-11.

Answer:

Since B is the midpoint, we have:

First angle = 40
Second angle = 50
Step-by-step explanation:
let 1st angle be 4x and 2nd angle be 5x
4x + 5x = 90 [Complementary means the sum of angles is 90]
=> 9x = 90
=> x = 90/9
=> x = 10
First angle = 4x = 4(10) = 40
Second angle = 5x = 5(10) = 50

( show your work ) The banner that football players run through is 18 feet high and 30 feet long. How much paper is needed to
construct a banner ?
Answer:
540 square feet worth of paper
Step-by-step explanation:
This is an area problem. Area is length multiplied by width. The provided length is 30 feet and the provided width is 18 feet. When they are multiplied, you get 540 square feet. Note that the height is the width in this context because if you laid the banner down, 18 would be the width. The banner is being held up, so the 18 feet is called the height.
