Answer:

  In step 4, Jim's answer is incorrect.

Step-by-step explanation:

In step 1, Jim swaps the order of addends using the commutative property of addition.

In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)

  6.1 +(-8.5 -1.3) . . . associative property

  6.1 +(-1)(8.5 +1.3) . . . distributive property

In step 3, Jim has used the properties of real numbers to form the sum of two of them.

In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

__

The descriptive statements about steps 2 and 4 are both true.

Directions: Find each value or measure. Assume that segments that appear to be tangent are tangent ​
SOVA2 [1]

Answer:

x = 7, x = 5

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord.

(1)

27x = 9 × 21 = 189 ( divide both sides by 27 )

x = 7

(2)

12(3x - 5) = 120 ( divide both sides by 12 )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

What slope is perpendicular to m= 5/8<br> m=-5/8<br> m=5/8<br> m=-8/5<br> m=8/5
MrRa [10]

Answer:

C) m =\frac{-8}{5}

The slope of the perpendicular line m =\frac{-8}{5}

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the slope of the given line is

    m =\frac{5}{8}

The slope of the perpendicular line

 = \frac{-1}{m}

The slope of the perpendicular line

 = \frac{-1}{\frac{5}{8} }

<u><em>Final answer</em></u>

The slope of the perpendicular line

                                          m =\frac{-8}{5}
