What value of x makes the equation true?(–12.3) • (–6.9) • 9.5 = x • 9.5 • (–12.3)


X=

Answers

Answer 1
Answer: ♥ Answer: x=-6.9

Solve:
You need to Simplify both sides of the equation.
806.265=-116.85x
Now: Flip the equation.
-116.85x=806.265
Lastly Divide both sides by -116.85.
(-116.85x)/(-116.85) = (806.265)/(-116.85)


Final answer: x=-6.9

Answers

y = -1/2x +2 1/2
General equation;
y = mx + c

Calculating the slope;
Change in y/ (change in x) = gradient m

(2-1)/(1-3) = - 1/2

Replacing m gives;
y= -1/2x + c

Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is 
y = -1/2x +2 1/2

An inequality is solved the same way an equation is solved, with one exception. If an operation is performed that changes ordering, then the comparison symbol is reversed. The usual case is multiplication or division by a negative number:

  2 > 1

  -2 < -1 . . . . both sides multiplied by -1

The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 1 and x = 3.Graph of 2 to the power of x plus 1

Answers

So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.

f(1)=2^1+1 which would be equal to 3

1,3

f(3)=2^3+1 which would be equal to 9

3,9

9-3/3-1=6/2

6/2=3

The average rate of change is 3.



Which set of values could be the side lengths of a 30-60-90 triangle? A. {4, 4 square root of 3, 8} B. {4, 4 square root of 2, 8 square root of 2} C. {4, 4 square root of 2, 8} D. {4, 4 square root of 3, 8 square root of 3}

Answers

Your answer is A.

When you have a 30-60-90 triangle, your sides will always have a set pattern. 

The side across from the 30 angle will be equal to n (in this case n = 4).

The side across from the 60 angle will always be equal to n√(3) (in this case, 4√(3)).

The side across from the 90 angle will always be 2n (in this case, 8).

You could go into trig or pythagorean theorem to prove this, but it's much simpler to remember it because it's a special triangle. 

So, you're answer is A.

Your answer is going to be letter A
