Find the value of x for which ABCD must be parallelogram

Mathematics

1 answer:

Since this is a parallelogram, both bases are equal. You can set them equal to each other to find x:

6+3x=x+14

Subtract x from both sides.

6+2x=14

Subtract 6 from both sides.

2x=8

Divide by 2.

x=4

Hope this helps! :)

Answer with steps!... Thanks

Answer:

A) False

B) True

Step-by-step explanation:

For A) First let's do x/11 = 15. If you solved it by now, you will know that the answer is 0.7333333. So now you just do 11x15. Because the answer is different then the answer we got when doing the division, the answer for A is false

For B) B is definitely true because equation are any mathematical sentences that have an equation symbol. So it's like saying 8x3=24 and 6x4=24. These two equations end up with the same answer so B is true.

I hope this helped you find out the rest :)

If g(x) = 3x − 4, what is the value of g−1(g(13))?

Vsevolod [243]

The function g(x) = 3x-4 is a linear function. Therefore the inverse does exist (which is also linear)

Because we have an inverse, this means we can use the rule
$g^{-1}(g(x)) = x$

Replace x with 13
$g^{-1}(g(x)) = x$
$g^{-1}(g(13)) = 13$

The answer is choice D

X+1/3y=4 in slope intercept form EXPLAIN

skad [1K]

Answer:

Y = 12

Step-by-step explanation:

x + 1/3y = 4

Multiply both sides of the equation by 3.

3 ⋅ 1 3 ⋅ y = 3 ⋅ 4

Simplify both sides of the equation:

1. Simplify both sides of the equation.

2. Multiply 3 by 4

How to simplify:

Cancel the common factor of 3

Rewrite the expression.

Multiply by 1

y = 3 ⋅ 4

Multiply 3 by 4
