Solve for x

Mathematics
1 answer:
Mademuasel [1]3 years ago
4 0

Answer:

x = 9

Step-by-step explanation:

Using the rule of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

Given

11^{x} = 11^{4} × 11^{5} = 11^{(4+5)} = 11^{9}

Since the bases on both sides are common, then equate the exponents

x = 9

-7/8 - (-h) = -7/12<br> solve for h<br> pls show work
Westkost [7]

Answer:

The answer is 7/24.

Step-by-step explanation:

I attached a picture, but I'll try to walk through it here.

1) A negative and a negative makes a positive, so h becomes positive.

2) I added 7/8 to both sides, in order to "isolate the variable", which simply means to get h by itself, on one side of the equation (you'll likely hear it said both ways).

3) I multiplied 7/8 by 3/3, and multiplied -7/12 by 2/2. This is known as a common denominator, which in this case is 24. You can only add and subtract fractions that have a common denominator.

4) Multiply both of the fractions to get 21/24 + (-14/24). "Adding a negative" is the same thing as subtracting.

5) 21 - 14 = 7, and since our denominators are the same, the answer is 7/24.

You can confirm the answer by substituting, or "plugging" 7/24 into your original equation, in place of h.

What is the solution to the equation X/2- 4 = 6? <br><br> x = 1 <br> x = 5 <br> x = 10 <br> x = 20
jeka94

[ Answer ]

\boxed{\bold{X \ = \ 20}}

[ Explanation ]

  • Solve: X ÷ 2 - 4 = 6

--------------------------

  • Rewrite Equation

\frac{X}{2} - 4 = 6

  • Add 4 To Both Sides

\frac{X}{2} - 4 + 4 = 6 + 4

  • Simplify

\frac{X}{2} = 10

  • Multiply Both Sides By 2

\frac{2x}{2} = 10 · 2

  • Simplify

X = 20

\boxed{\bold{[] \ Eclipsed \ []}}

Which is most likely the correlation coefficient for the<br> set of data shown?
beks73 [17]

Answer:

Step-by-step explanation:

It would -.21. Negative because the trend of the line sort of resembles a line with a negative slope, and .21 because the dat points do not even remotely resemble a line. The closer that number is to 1, the closer the dots will be to fitting on the line.
