Answer:

y = -2/3x - 1

Step-by-step explanation:

First, find the slope so you can see that when x goes up by 3, y goes down by 2. This means that the slope is -2 divided by 3, or -2/3.

You can see in the picture that the y-intercept is at the point (0, -1).

That means the equation would be y = -2/3x - 1

The table shows a proportional relationship between the number of pounds of bananas purchased and the total cost of bananas.

Liula [17]

Answer:

Choice A, C and E

Step-by-step explanation:

Your table is poorly presented

Given

x y

$\begin{array}{cc} {3} & {1.47} \ \\ {5} & {2.45} \ \\ {9} & {4.41} \ \ \end{array}$

First, we calculate the constant of proportionality (k)

$k = \frac{y}{x}$

For (3,1.47)

$k = \frac{1.47}{3}$

$k = 0.49$

For (5,2.45)

$k = \frac{2.45}{5}$

$k = 0.49$

For (9,4.41)

$k = \frac{4.41}{9}$

$k = 0.49$

From the above calculations, the constant of proportionality is 0.49.

So, the usable rows must also have 0.49 as their constant of proportionality

Choice A

$(x,y) = (2,0.98)$

$k = \frac{0.98}{2}$

$k = 0.49$ --- This is usable

Choice B

$(x,y) = (7,4.45)$

$k = \frac{4.45}{7}$

$k = 0.64$ --- This is not usable

Choice C

$(x,y) = (6,2.94)$

$k = \frac{2.94}{6}$

$k = 0.49$ --- This is usable

Choice D

$(x,y) = (1,0.54)$

$k = \frac{0.54}{1}$

$k = 0.54$ ---- This is not usable

Choice E

$(x,y) = (8,3.92)$

$k = \frac{3.92}{8}$

$k = 0.49$ --- This is usable

Explain how to solve the inequality n/-8 < -40

stiks02 [169]

Answer: n>320

Explanation:

Let's solve your inequality step by step.

Step 1: Simplify both sides of your inequality

n/-8 < -40

-1/8n < -40

Step 2: Multiply both sides by 8/(-1).

(8/-1)*(-1/8n)< (8/-1)*(-40)

n>320

----Your answer is n>320.----
