Answer:

Answer choice C

Step-by-step explanation:

The unit price of a product is how much that product costs for a single unit, or in this case pound. 7 pounds of dog food to 21 dollars has the same ratio as 1 pound of dog food to three dollars, meaning that the unit price of dog food is $3 per pound. Hope this helps!

NEED HELP WITH PART B
Sergeu [11.5K]

Answer:

y = -20x + 100

Step-by-step explanation:

As per your requirement For Part B, the solution is

The equation in slope-intercept form to model the relations is below:-

To reach 2 points on the graph the line passes through

lets use p1(0, 100), p2(1, 80)

now we will compute the slope:

m = \frac{(y2 - y1)}{(x2 - x1)}

m = \frac{(80 - 100)}{(1 - 0)}

= -20

and now use line equation in form point-slope:

y - y1 = m(x - x1)

y - 100 = -20(x - 0)

y = -20x + 100

If the domain (or pre-image) is (-4, -2), (5, 9), (-6, 2) and the range (or image) is
Neko [114]

Answer:  90 degrees clockwise

This is equivalent to 270 degrees counterclockwise

The rule for either rotation is (x,y) \to (y,-x)

The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).

The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).

Are -2x + 9 = 7 and 2x = 2 equivalent?​
DochEvi [55]

Answer:

Yes because the answer to both of them is 1

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+9=7

Step 1: Subtract 9 from both sides.

−2x+9−9=7−9

−2x=−2

Step 2: Divide both sides by -2.

−2x

−2

=

−2

−2

x=1

Answer:

x=1    

Let's solve your equation step-by-step.

2x=2

Step 1: Divide both sides by 2.

2x

2

=

2

2

x=1

Answer:

x=1
