The coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

What is midpoint of line segment?

The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.

Here, the mid point of line EF is M with coordinates (1,-1) with coordinates  of E(-3,2) therefore, using mid point formula to find coordinates of F(x,y)

[tex]\begin{aligned}\frac{-3+x}{2}&=1\\x&=2+3\\&=5\end{aligned}[/tex]

and for y coordinates of F :

[tex]\begin{aligned}\frac{2+y}{2}&=-1\\y&=-2-2\\&=-4\end{aligned}[/tex]

Therefore, the coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

Answer:

yes 4fl oz bottle of orange juice that costs $12 dollars is better to buy

Step-by-step explanation:

2 bottles of orange juice=8$

if you split 8$, you get 4$ that means each bottles of orange juice is 4$

so if you get 4 bottles of orange juice it is 4$x4$= 16$ The question says that 4 bottles cost 12$ its supposed to be 16$. So the 4 fl oz bottle of orange juice that costs 12$ dollars is better to buy.

1 bottle=4$               2x4=8$ (the first equation)    

1bottle=4$                4x4=16 (the second equation)   But the question says we got the bottle of orange juice for 12$ its supposed to be 16$ that is a huge discount. so yes the answer is correct.

Answer:

60° and 67°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(49)

17x + 8 is an exterior angle of the triangle, thus

17x + 8 = 50 + 10x ( subtract 10x from both sides )

7x + 8 = 50 ( subtract 8 from both sides )

7x = 42 ( divide both sides by 7 )

x = 6

Thus

∠ C = 10x = 10(6) = 60°

(50)

99° is an exterior angle of the triangle, thus

2x + 10 + 6x + 1 = 99 , that is

8x + 11 = 99 ( subtract 11 from both sides )

8x = 88 ( divide both sides by 8 )

x = 11

Thus

∠ T = 6x + 1 = 6(11) + 1 = 66 + 1 = 67°

Answer:

C.) [tex]x^2+2x-3[/tex]

Step-by-step explanation:

They give us the function; [tex]P(x)=x^3-7x+6[/tex], which is then divided by the binomial, [tex](x-2)[/tex].

We can use polynomial synthetic division to solve this! First, let's understand how we must use it properly.

As we can tell from the function [tex]P(x)=x^3-7x+6[/tex] , there is an exponent value of 3, and an "invisible" exponent of one on -7x. When doing the synthetic division, we must put in a zero before we introduce the term '-7x' in our process of division.

The binomial [tex](x-2)[/tex] tells us that we are dividing the function by that, but we have to take the opposite value of the integer value, and here's why.

[tex](x-2)=0[/tex]

If we are trying to solve for 'x' here, we have to add plus sides by two, and we get x=2. That is what we have to put on the left side of the synthetic division we will use, we are essentially stating that one of the root/solution(s) to the function is 2, and we get verification of that when the synthetic division results in zero towards the end.  

Then when the synthetic division has been done, since we are dividing by that binomial, we take out the values that we know already, which are '1', '2', and '-3', and take away one power of exponent to each of them (if applicable)

Thus, leaving us with our answer, [tex]x^2+2x-3[/tex].

The required quetient of the given expression is x² - 2x -3. Options C is correct.

It is a method for performing division of polynomials, with little writing and lesser calculations than complex division.

here,
synthetic division is given as,
put divisor equal zero,
x - 2 = 0 so x = 2

Now,
Arranging the division with zero and coefficients and constant of the expressions,

2    |   1  0   -7    6
     +      2   4   -6
----------------------------
          1  2  -3   0

So, the question, by synthetic division is given as x² + 2x -3.

Thus, the required quetient of the given expression is x² - 2x -3. Options C is correct.

Step-by-step explanation:

Answer:

x = 60

Step-by-step explanation:

x/12 is the same as 1/12x

so now the equation is 1/12x+1=6

then to simplify it even more we do -1 from both sides so

1/12x+1=6

         -1  -1

again the equation is 1/12x=5

then we multiply both sides by 12 and get x = 60
