Answer:

Step-by-step explanation:

All you have to basically do on this one is go backwards.

The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).

12-4=8

Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.

8/4=2

Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12

Hope this helped!

D is halfway between A and B

so the coordinates of D are (2,2)

E is halfway between A and C so the coordinates of E are (-1,1)

now you need to find the gradient/slope of DE and BC using the formula:

$\frac{y2 - y1}{x2 - x1}$

<h3>Gradient of DE: </h3>

SUB IN COORDINATES OF D AND E

$\frac{1 - 2}{ - 1 - 2}$

therefore the gradient of DE is 1/3.

<h3>Gradient of BC:</h3>

SUB IN COORDINATES OF B AND C

 $\frac{ - 2 - 0}{ - 3 - 3}$ 

therefore the gradient of BC is -2/-6 which simplifies to 1/3.

<h3>therefore, BC and DE are parallel as they both have a gradient/slope of 1/3 and parallel lines have the same gradient</h3>

Can someone plz help me solved this problem! Need help ASAP! Help me !

lana66690 [7]

Answer: 5, 8

Step-by-step explanation:

The difference between 3 times a number and -8 is BETWEEN 23 and 32

Note: "difference" means subtraction --> 3x - (-8) --> 3x + 8

23 < 3x + 8 < 32

15 < 3x < 24 subtracted 8 from all 3 sides

--> 5 < x < 8 divided 3 from all 3 sides

the function f(x)= sqrt x is translated left 5 units and up 3 units to create the function g(x). what is the domain of g(x)?

Zinaida [17]

Answer:

x ≥ -5

Step-by-step explanation:

If we have a translation to left c units, we write " x + c " in the function, and

If we have a translation to right c units, we write " x - c" in the function

If we have vertical translation up b units, we "add b to the function", and

If we have vertical translation down b units, we "subtract b to the function"

The parent function is $f(x)=\sqrt{x}$

Since translation left 5 units and up 3 units, we can write:

$f(x)=\sqrt{x+5} + 3$

The domain is affected by the square root sign and we know the number under the square root CANNOT be negative, so we can say:

x + 5 ≥ 0

x ≥ -5

This is the domain.

6 is what percent of 8?

kvasek [131]

6 is 75% of 8. 6/8 can be simplified to 3/4, which is easier to see as 75%.
