It is A, C

because they are all the same

because they are all the same

**Answer:**

The correct option are A and C.

**Step-by-step explanation:**

If two lines intersect each other at a point, then each of the pairs of opposite angles made by these lines are called vertical angles.

From the given figure it is noticed that the line SA and DE intersect each other at point O.

The line OB touch the lines SA and DE. It does not intersect the lines, therefore the line OB does not make any vertical angle.

**Therefore option A and C are correct.**

We can solve the system of equations to check the number of system of the solutions.

y=-6x+2 ...(1)

-12x-2y=-4 ...(2)

Substitute -6x+2 for y in equation (2). So,

-12x-2(-6x+2)=-4

-12x+12x-4=-4 (By distribution property).

-4=-4 (-12x and +12x has been cancel out).

Notice x has vanish from the above equation and we are left with -4=-4 which is correct.

So, **the system has infinte number of solutions.**

If you want to solve the equation x / 5 + 9 = 4, then you'll have to make x be on it's own, like this: x = -5 * 5, which gives us -25! Hope this helped! Brainliest is always appreciated.

Hello!

Judging by the model and question at hand I have figured out that the best way to come across the solution you are looking for is to use the**complementary angle rule!**

This entitles that ∠3+∠4=90°

And we already have one of these angles!

So, the new equation we should have is ∠4+39°=90°

The next step you should take is to isolate the angle!

To do this you want to subtract 39° from both sides of the equation.

The outcome should look something like this ∠4=51°.

**And thus your answer! m∠4=51°**

Hope this helped!

(x - 6) cannot be negative as there are no real square roots of a negative quantity so x must be >= 6

So the domain is 6 =< x < infinity

So the domain is 6 =< x < infinity

C. octagon but even though u dont have no picture

**Answer: The correct option is**

**(A) 12.**

**Step-by-step explanation: **We are given to find the **length of MN from the figure shown.**

From the figure, we note that LMN is an isosceles triangle where

We know that

in an isosceles triangle, the **lengths of the sides opposite to the equal angles are equal.**

**So, in triangle LMN, we have**

**Therefore, the length of side MN is**

**Thus, the required length of MN is 12 units.**

**Option (A) is CORRECT.**

Carrie will spend 248.75 on 25 t-shirts. Multiply $9.95 by 25.

It would be (-3, 0) (work is shown above)

There are no real roots of √x where x is negative.

so the domain is 0 ≤ x < ∞

so the domain is 0 ≤ x < ∞

**Answer:**

4.08 inches.

**Step-by-step explanation:**

A cube has six sides, and each of the sides has area of , where is the length of the edge of the cube.

Thus the total surface area of the cube is

Now we are told that this surface area is 100 square inches, therefore , and now we can solve for :

The answer is C because a line contains all the values (including decimals) and the graph on the right only has the integer values (positive and negative whole numbers).

We have that

set of data [8, 12, 15, 17, 18]

**step 1**

Find the mean

[8+ 12 + 15 + 17 + 18]/5-------> 70/5------> 14

**step 2**

for each number: subtract the Mean and square the result

(8-14)²----->36

(12-14)²----> 4

(15-14)²----> 1

(17-14)²----> 9

(18-14)²----> 16

**step 3**

work out the mean of those squared differences

[36+4+1+9+16]/5-----> 66/5-----> 13.2----> this value is called the "Variance"

**step 4**

Take the square root of that

standard desviation=√13.2-----> 3.63-------> 4

**the answer is**

The answer is 3.4×10^-10

X=mother's age

y=son's age

3y=x

x+y=38+(5*2)

therefore x=36 and y=12

y=son's age

3y=x

x+y=38+(5*2)

therefore x=36 and y=12

The half-life of helium-5 is 7.6 × 10^{-22} seconds, and the half-life of helium-9 is 7 × 10^{-21} seconds.

Approximately the half-life of helium-9 is greater than that of helium-5.

**Answer:** 9 times.

Approximately the half-life of helium-9 is greater than that of helium-5.

The answer would be A.

B is wrong cause temperature increases and decreases.

C is wrong cause the dot would be curved near the end

D is wrong cause how could 1 line represent 2 measures of a shape

The equivalent polynomial is 12x^2 -23x - 24.

You can get this by multiplying the two parenthesis by each other.

First start by multiplying the two front numbers:

4x * 3x = 12x^2

Then multiply the outermost numbers:

4x * -8 = -32x

Then multiply the innermost numbers:

3x * 3 = 9x

Then multiply the last numbers:

3* -8 = -24

Now combine all of them to get the above polynomial.

What is the answer choice?

When solved

(x + 1 < 4) ∩ (x - 8 > -7)

becomes:

(x+1-1 < 4-1) ∩ (x - 8 +8 > -7+8 )

(x < 3) ∩ (x > 1).

and if you change places it will become even more obvious:

( 1<x ) ∩ ( x < 3 )

meaning: x is set of all numbers greater than 1 and less than 3 or otherwise:

**{x | 1 < x < 3}**

(x + 1 < 4) ∩ (x - 8 > -7)

becomes:

(x+1-1 < 4-1) ∩ (x - 8 +8 > -7+8 )

(x < 3) ∩ (x > 1).

and if you change places it will become even more obvious:

( 1<x ) ∩ ( x < 3 )

meaning: x is set of all numbers greater than 1 and less than 3 or otherwise:

The 2 red lines on the triangle mean that the 2 sides are equal.

Because the 2 sides are equal, Angle D is the same as angle C.

So now angle C & D are both 52 degrees, we can find Angle E

180 - 52 - 52 = 76 degrees

Angle DEF + Angle E need to equal 180 degrees

Angle DEF = 180 - 76 =**104 degrees**

Because the 2 sides are equal, Angle D is the same as angle C.

So now angle C & D are both 52 degrees, we can find Angle E

180 - 52 - 52 = 76 degrees

Angle DEF + Angle E need to equal 180 degrees

Angle DEF = 180 - 76 =

The equation in standard form should be 2x^2 + 7x - 15 = 0

Factored the expression is (2x - 3)(x + 5).

In order to find the factored portion, you must look for factors of the front number (2) to use in the front of the parenthesis and factors of the last number (-15) to go in the end.

When we use the ones that we have above, it distributes to the overall end result.

(2x - 3)(x + 5)

2x^2 - 3x + 10x - 15

2x^2 + 7x - 15
