Answer:

\Huge\boxed{\mathsf{\Rightarrow X=-6}}}

Step-by-step explanation:

Isolate x on one side of the equation.

2(-2x-4)  ← (Expand by using with distributive property.)

<u><em>DISTRIBUTIVE PROPERTY</em></u>

⇒ A(B+C)=AB+AC

⇒ A(B-C)=AB-AC

A=2

B=(-2x)

C=4

2(-2x)-2*4

-2*2x-2*4

-2*2x-2*4 (Solve.)

-2*2-2*4=-4x-8

Rewrite the equation problem.

10-x=-4x-8

10-x-10=-4x-8-10 (Subtract 10 from both sides.)

Solve.

-x=-4x-18

-x+4x=-4x-18+4x (Then, add 4x from both sides.)

3x=-18 (Solve.)

3x/3=-18/3 (Divide by 3 from both sides.)

-18/3 (Solve & Simplify.)

-18/3=-6

X=-6

\Large\boxed{\mathsf{X=-6}}}

Therefore, the correct answer is x=-6.

Answer:

-6 (All Real Numbers)

Step-by-step explanation:

First, you need to solve it and then determine if it is a solution or not. -6 is an integer, making it a real number. Therefore, the answer is "All Real Numbers".

<em>Hope this helps! :-)</em>

DOES ANYONE UNDERSTAND QUADRATIC APPLICATIONS FOR ALGEBRA 1???? PLS DONT RESOND IF YOU DINT KNOW
lilavasa [31]

Answer:

1 ) Vertex form.

2 ) Standard form.

3 ) I'm not sure about this one, but there are only 3 forms, in which the last one is factored form, and the other two are above, so it must be factored form.

Step-by-step explanation:

1 ) Vertex form : y = a( x - h )² + k

Vertex form shows you where the vertex(the lowest/highest point aka ( h, k ) ) of the parabola is, without graphing it. (But you could graph it and find the vertex like that, I recommend you use desmos graphing)

2 )Standard form : y = ax² + bx + c

Standard form can be used to show the y-intercept( aka c ), in this case, where the snowball was thrown from. (Again, you can graph it and find where he parabola hits the y axis)

3 ) Factored form : ( ax + c )( bx + d )

Factored form tells us the x-intercepts, or in this case where the snowball landed or how long the snowball is in the air. (like i said, you could graph it, and find the points(there could be only one or maybe none in some cases) that are on the x axis)

I know this was four days ago, but I hope this helped you understand a little better.

Question 17 of 25
Brilliant_brown [7]

Answer:

c

Step-by-step explanation:

y = \frac{5}{2} x + 2 → (1)

2y = 5x + 4 ( divide through by 2 )

y = \frac{5}{2} x + 2 → (2)

the 2 equations are the same and will have infinitely many solutions

The figure shows a kite inside a rectangle. Which expression represents the area of the shaded region? 2x2 4x2 6x2 8x2
notka56 [123]
The picture in the attached figure

we know that
area of the <span>the shaded region=area of rectangle -area of a kite

area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²

area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²

area of the the shaded region=8x²-4x²-----> 4x²

the answer is 
4x²
