5. If a = b, and b = c then a = c is the transitive property.

6. The converse is switching the order of the statement.

The answer would be If A <15, then a <10: true

7. You have RS + ST = RT

Using subtraction property solve for RS by subtracting ST from both sides to get: RS = RT-ST

8. The addition property would be adding the same thing to both sides:

So. If p=q, then p+s = q+s

9. Vertical angles are the same:

6x-22 = 4x+2

Subtract 4x from both sides:

2x-22 = 2

Add 22 to both sides:

2x = 24

Divide both sides by 2:

x = 12

Crank

Answer:

$A=81(\pi-1)\ in^2$

Step-by-step explanation:

step 1

Find the area of the plate

The area of a circle is given by the formula

$A=\pi r^{2}$

we have

$r=18/2=9\ in$ ---> the radius is half the diameter

substitute

$A=\pi (9)^{2}\\A=81\pi\ in^2$

step 2

Find the area of the square napkin folded (is a half of the area of the square napkin)

we know that

The diagonal of the square is the same that the diameter of the plate

Applying Pythagorean theorem

$D^2=2b^2$

where

b is the length side of the square

we have

$D=18\ in$

substitute

$18^2=2b^2$

solve for b^2

$b^2=162\ in^2$ -----> is the area of the square

Divide by 2

$162/2=81\ in^2$

step 3

Find the area of the space on the plate that is NOT covered by the napkin

we know that

The area of the space on the plate that is NOT covered by the napkin, is equal to subtract the area of the square napkin folded (is a half of the area of the square napkin) from the area of the plate

$A=(81\pi-81)\ in^2$

simplify

$A=81(\pi-1)\ in^2$

3x-8<23 and -4x+26>6

Papessa [141]

Answer:

3x-8<23 and -4x+26>6

x<31/3 x<5

Step-by-step explanation:

3x-8<23

Add 8 to both sides

3x<31

Then divide 3 to both sides

x<31/3

and -4x+26>6

Minus 26 to both sides

-4x>-20

You divide -4 to both sides

Keep in mind that everytime you divide a negative the inequality will change so > will be <

x<5

Which statement is true regarding the functions on the graph?

sergey [27]

Answer:

f(3) = g(3)

General Formulas and Concepts:

Algebra I

Reading a Coordinate Graph
Coordinates (x, y)
Solving systems of equations by graphing
Functions
Function Notation

Step-by-step explanation:

According to the graph, we see that both lines intersect at x = 3. Therefore, that means both lines at that x point will have the same y value. Both f(3) and g(3) would equal 6, leading us to the answer of f(3) = g(3).
