Hello. I have tried everything and I still can't find the right answer. Can somebody please explain how to do this to me? Thanks so much!

Answer:

-1

Step-by-step explanation:

so -x-6 and x-4 are both = to y so that means they are both = to each

other so -x-6=x-4 add x to both sides -6=2x-4 add 4 to both sides 2x = -2 simplify by divide by 2 so x=-1

Answer:

Take the second equation and add 4 to both sides, this gives you x=y+4. The plug in y+4 on the first equation, so y=-(y+4)-6, distribute the negative to everything inside the parentheses, and you get y=-y-4-6. Combine like terms and you get y=-y-10, then add y to both sides, you get 2y=-10, divide both sides by 2 and you get y=-5.

Then plug -5 into the second equation and you get -5=x-4, add 4 to both sides and you get -1=x.

If you want to check your answer, just plug in x and y to either of the equations and see if it makes a true statement.

Answer:

LV = OE =34

Step-by-step explanation:

Due to the rectangle theory,

LV = OE

3x + 10 = 5x-6

-2x = - 16

x = 8

LV = 3(8) +10 = 34

OE= 5(8)-6 = 34

They are approximately 4 yards. Look at a coordinate grid and locate where (-5, -2) and (-8, -3) are and you will see they are 4 yards apart. The answer would be C.

Answer:

y = 140

Step-by-step explanation:

All angles inside the triangle will equal 180

Set your formula up as

180 = x + 120 + 20

180 - 120 - 20 = x

40 = x

y+x will also equal 180, therefore

180 = y + x

180 = y + 40

180 - 40 = y

140 = y

Answer:

2m + 3

Step-by-step explanation:

Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.

3 + twice of Kylie's marbles = twice of Kylie's marbles + 3

The amount of marbles kylie has is represented with m, making it (2 x m) + 3 = 2m + 3.

Answer:

[tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]

Step-by-step explanation:

Since our foci are located on the x-axis, then our major axis is going to be the horizontal transverse axis of the hyperbola:

Formula for hyperbola with horizontal transverse axis centered at origin

Since we are given our directrices of [tex]x=\pm3[/tex] and foci of [tex](\pm4,0)[/tex], then we can set up the directrices equation to solve for [tex]a^2[/tex]:

[tex]x=\pm\frac{a^2}{c}\\ \\\pm3=\pm\frac{a^2}{4}\\ \\12=a^2[/tex]

Now we can determine [tex]b^2[/tex] to complete our equation for the hyperbola:

[tex]a^2+b^2=c^2\\\\12+b^2=4^2\\\\12+b^2=16\\\\b^2=4[/tex]

Therefore, our equation for our hyperbola is [tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]

Answer:

No

Step-by-step explanation:

If (x - 3) is a factor then x = 3 is a root and the polynomial will equal zero for x = 3 , that is

3³ - 3(3)² + 2(3) + 2

= 27 - 3(9) + 6 + 2

= 27 - 27 + 8

= 8

since the polynomial ≠ 0 for x = 3 then (x - 3) is not a factor

Answer:

People to tables: 5:1

Tables to people: 1:5

Step-by-step explanation:

The statement that is true about the given sample is that;

B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,

We are given;

Sample size; n = 420

Sample proportion; p^ = 65%

Now, from the sample size and proportion, we can say that;

Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.

Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.

Answer:

The zeros are -2, 1, and 2

Step-by-step explanation:

You have to set each individual equation equal to zero.

ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2

as for the y intercept I don't know

Answer:

see explanation

Step-by-step explanation:

g(x) = (x + 2)(x - 1)(x - 2)

To find the zeros let g(x) = 0 , then

(x + 2)(x - 1)(x - 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

The zeros are x = - 2, x = 1, x = 2

To find the y- intercept substitute x = 0 into g(x)

g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4

The y- intercept is 4 or (0, 4 )

Answer:

The length of the missing leg is six

Step-by-step explanation:

Assuming that this is a right triangle, you can use the Pythagoras theorem

12^2+x^2=sqrt180^2

144+x^2=180

x^2=36

x=6

Therefore, the length of the missing leg is six.

Answer:

Taking the above as a right angled triangle...

Pythagoras' rule can be applied to get the Missing side.

It goes...

Hyp² = Opp² + Adj²

Which translates to Hypotenuse, Opposite and Adjacent respectively.

Hyp = √180

Opp= 12

So we're missing Adj

Making adj the subject.

Adj = √ Hyp² – Opp²

= √[(√180)² – (12)²

= √ [ 180 – 144]

= √36

Adj = 6ft.
