find the value of x root (4/7)^2x-1=16/49​

Answers

Answer 1

Answer:

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given expression:

                     [tex](\frac{4}{7}) ^{2x - 1}[/tex]   = [tex]\frac{16}{49}[/tex]

  Solve for x;

Solution:

    16  = 4²

   49 = 7²

  So;

           [tex](\frac{4}{7}) ^{2x - 1}[/tex]  = [tex]\frac{4^{2} }{7^{2} }[/tex]

          [tex](\frac{4}{7}) ^{2x - 1}[/tex]   = [tex](\frac{4}{7} )^{2}[/tex]

     Now;

              2x - 1 = 2

              2x = 3

                x  = [tex]\frac{3}{2}[/tex]

Answers

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

Daisy decides to go on a hike to a picnic area. Her map shows that when she reaches the giant oak tree she will have completed 60% of the hike. When Daisy reaches the giant oak tree she has walked 18 kilometers.

Answers

Answer:

12 km

Step-by-step explanation:

Question:How many kilometers does Daisy have left to reach the picnic area?

Given

60% of the hike = 18 km

Let the distance be x, then

0.6x = 18x = 18/0.6x = 30 km

Remaining distance is:

30 - 18 = 12 km

Sue Ling gave her dad a $50 gift certificate. He plans to buy a $12 book on home repair
and as many drill bits as he can for $1.79 each. Choose the inequality that shows x, the
number of drill bits he can buy.
I

Answers

Answer:

12 + 1.79(x) ≤ 50

Number of drill bits = 21

Step-by-step explanation:

Given:

Total amount = $50

Amount of book = $12

Price of each bit = $1.79

Find:

Number of drill bits

Computation:

Assume, Number of drill bits = x

So,

12 + 1.79(x) ≤ 50

1.79(x) ≤ 38

x ≤ 21.220

Number of drill bits = 21

Which equation represents a line which is perpendicular to the line
6x + 7y = -42?
Somebody please help?

Answers

Answer:

y  = [tex]\frac{7}{6} x - 5[/tex]

Step-by-step explanation:

 Given expression:

        6x + 7y  = -42

To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.

Solution:

Equation of any straight line is given as;

        y  = mx + c

where x and y are the coordinates

                m is the slope

                c is the intercept

Let us now find the slope of the line;

          6x + 7y  = -42

              7y = -6x - 42

   divide through by 7 to give;

             y = [tex]-\frac{6}{7} x[/tex] - 6

The slope is  [tex]-\frac{6}{7}[/tex]

     A line perpendicular will have a slope of a negative inverse;

          - ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]

The answer is A.

Answers

The expression that represents D is (q²+7)/f

The subject of formula is a way of representing a variable to represent all other variables in a function

Given the expression

fD - 7 = q²

Add 7 to both sides

fD - 7 + 7 = q² + 7

fD = q² + 7

Divide both sides by f

fD/f = (q²+7)/f

D =  (q²+7)/f

This is the table of values of a function. Write the output when the input is n.

Input= 4 6 9 n
Output= 2 4 7 ?

Answers

Answer:

n-2

Step-by-step explanation:

1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: take the input value and subtract two.

2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.

Can you help with these two plz? Number a and b if you can do c and d for me that would be great as well!

Answers

Answer:

a) x = 60. b) b = 110. c) x = 20. d) x = 30.

Explanation:

For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.

For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.

For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.

For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.
