try mutipliying 8 times 5 that will give you your answer because 6 times 5 gave you the numerater so try the denominator

Solve the quadratic equation numerically (using tables of x- and y- values). -4x=-x2+12

Levart [38]

-4x=-x2+12 should be written <span>-4x=-x^2+12, with " ^ " representing exponentiation.

You are to invent a table of x values and find the difference between -4x and -x^ 2+12. The smaller the difference, the closer you are to finding the correct root, x.

To get you started:

x -4x x^2+12 difference
--- ------------ ---------------- --------------
2 -8 16 24 (pretty bad!)
-4 16 28 12 (better)
-10 40 112 72 (much worse)

To answer this problem correctly, you must present such a table, even tho' it'd be faster to use the quadratic formula (or some other method) to find x.

(07.03 MC) An equation is shown below: 9(3x − 16) + 15 = 6x − 24 Part A: Write the steps you will use to solve the equation, and

Alik [6]

Answer: See steps and explanation below. The value 5 makes the equation true.

9(3x - 16) + 15 = 6x - 24 Distributive Property

27x - 144 + 15 = 6x - 24 Combine like terms

27x - 129 = 6x - 24 Subtract 6x from both sides

21x - 129 = -24 Add 129 to both sides

21x = 105 Divide both sides by 21

I need help with this what would k be? Or is she correct

charle [14.2K]

Answer:

The value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2

Step-by-step explanation:

We need to determine the value of k if $2^4=16^k$

We are given:

$2^4=16^k$

Exponent rule, if bases are equal the exponents are equal

We can write $16= 2^4$

$2^4=(2^4)^k\\2^4=2^{4k}$

Now since the base is same, i,e 2 so, the exponents will be same

$4=4k\\k=1$

So, the value of k=1

So, Maura claim is incorrect. The value of k=1 and not k=1/2

show that 1/2 ÷ 3 =1/6 by using a model.Explain why the result is less than the number you started with 1/2

aleksklad [387]

Answer:

True

Step-by-step explanation:

Let's see if it is true....

1/2 ÷ 3

Rewritten,

=1/2 ÷ 3/1

(All numbers have a denominator of 1)

Flip the pancake!

=1/2 * 1/3

(When dividing fractions you flip one of the fractinons numerator and denominator)

The answer is,

=1/6

Therefore, the original statement 1/2 ÷ 3 = 1/6 is true!

Now the model is in the link below!

Hope this helps!
