Answer:

a = 4

Step-by-step explanation:

Assuming you require to find the value of a

In a rhombus all the sides are congruent, thus

9a - 13 = 3a + 11 ( subtract 3a from both sides )

6a - 13 = 11 ( add 13 to both sides )

6a = 24 ( divide both sides by 6 )

a = 4

Then

XW = 9a - 13 = 9(4) - 13 = 36 - 13 = 23

Thus the sides of the rhombus are 23 units

What happens to the value of the expression 80-2r80−2r80, minus, 2, r as rrr decreases? Choose 1 answer: Choose 1 answer: (Choic
Pie

Answer:

(Choice B) B It decreases.

Step-by-step explanation:

According to the situation, the solution of the value of the expression is as follows

Let us assume

r         80 -2r

5        80 - 10 = 70

4        80 - 8 = 72

3        80 - 6 = 74

2        80 - 4 = 76

1         80 - 2 = 78

As we can from the above calculation that expression value risen if r value decreased

Therefore the correct option is B.

Line CD passes through points C(3, -5) and D(6, 0) . what is the equation of the line CD in standard form?​
Kazeer [188]

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find <em>b</em>

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

And we have our final answer!
