Answer:

  11.  x = 8

  12.  x = 15

  13.  x = 9

Step-by-step explanation:

This statement of the applicable relation is perhaps a little different than the one(s) you may have seen: From the point where the segments meet, the product of the length of segment to one side of the circle and the length of segment to the other side of the circle is the same for both segments. When the segment is tangent to the circle, those two circle intersection points are the same point.

This rule is applicable for all of these problems. Once the relation is written, the equation can be divided by the coefficient of x to find the value of x.

__

<h3>11.</h3>

  12·4 = 6x

  x = 48/6 = 8

__

<h3>12.</h3>

  x·x = 9·(16+9)

  x = √(9·25) = 15 . . . . take the square root

__

<h3>13.</h3>

  x·16 = 8·(8+10)

  x = 144/16 = 9

Answer A, B, C, Please, and Thanks!
DochEvi [55]

A) The variable on the horizontal axis of the graph (the independent variable) is "pounds of rice". That is what the first number in the ordered pair (6, 18) represents.

The variable on the vertical axis of the graph (the dependent variable) is "total cost in dollars". That is what the second number in the ordered pair represents.

(6, 18) represents that the total cost of purchasing 6 lbs of rice is $18.

B) The unit price is found at the point where the independent variable has the value 1. That would be at the point (1, 3), which indicates the unit price is $3 per pound.

C) You would have to buy 4 lbs of rice for the total cost to be $12. There are at least two ways to find the answer.

  1. Draw a horizontal line on the graph at cost = $12. It intersects the graph at lbs = 4.
  2. Divide the total cost by the unit price. $12/($3/lb) = 4 lb.

Write an equation in standard form given: m= -3/4 and b=5.
Dmitry [639]

Answer:

3x+4y=20

Step-by-step explanation:

The slope-intercept equation would be:

y=mx+b

y=-3/4(x)+5

But standard form is

ax+by=c

We can obtain this by moving the -3/4(x) to the left side

\frac{3x}{4} +y=5

Multiply both sides by 4 to get rid of the fraction

3x+4y=20

What is the answer to - 5y = - 5 and. 7x +6y=7
Vikentia [17]

Answer:

(1/7, 1)

Step-by-step explanation:

By "answer," you probably meant "solution."  What is the "solution of the system of linear equations

- 5y = - 5

+ 7x +6y=7

The first eqation can be solved for y:  y = 1.  Substitute 1 for y in the secon equation.  Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.

The solution to this system is (1/7, 1)
