2 answers:

Hey there!

The answer is B, the commutative property of multiplication.

The commutative property of multiplication states that you get the same value in an expression, not depending on the order. See here, you have -3/9 and 2, and even though they're in different orders, when you multiply them, they're equal.

Notice how it doesn't work in other operations such as subtraction and division (it works in addition):

10/5 ≠ 5/10
4-10 ≠ 10-4

However,

5 + 10 = 10 + 5

Hope this helps!

Tyler filled up his bathtub, took a bath, and then drained the tub. The function

TiliK225 [7]

Answer:

B(0) = 0 depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0

B(1) represents the function one minutes after filling began.

B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.

Step-by-step explanation:

The function gives depth of water in inches 7 minutes after filling began

A.) B(0)=0

The statement B(0) = 0 means the depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0

B.) B(1)

B(1) represents the function one minutes after filling began.

C.B(9)=11

B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.

At the farmers market two pounds of peaches cost 4.20 how much would five pounds cost show work

Marizza181 [45]

Hey!

You can make a proportion:

$\frac{2}{\$ 4.20} = \frac{5}{x}$

Cross multiply

$\$ 4.20 \times 5 = \$ 21$

Divide by 2

$\$ 21 \div 2 = \$ 10.5$

<em>5 pounds would cost $10.50</em>

Good luck and hope this helps! :)

Which of the following equations is a direct variation?<br> y=3X+2<br> y=5<br> y=2x<br> y=8x+6

Alex

$direct \: varition \: means \: y \alpha x \\ it \: becomes \: y = kx$
So y=2x is the only answer that fit y=kx, while k=2

A triangle has vertices A(1, 1), B(2, 4), and C(4, 2). Line p is parallel to side AB and contains point C.

kenny6666 [7]

Answer:

$p:y = 3x-10$

Step-by-step explanation:

We are given the following in the question:

A(1, 1), B(2, 4), C(4, 2)

i) Slope of AB

$A(1, 1), B(2, 4)\\\\m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{4-1}{2-1}=3$

Thus, slope of AB is 3.

ii) Point slope form

The point slope form of a line can be written as:

$y - y_1 = m(x - x_1)$

The point intercept form of line can be written as:

$y = mx + c$

The line is parallel to AB and contains point C(4, 2). Since line p is parallel to AB, line p will have the same slope as line AB

Putting values, we get,

$y - 2 = 3(x-4)\\y = 3x-12+2\\y = 3x-10$

which is the required slope intercept equation of line p.
