Answer:

(0,3)

Step-by-step explanation:

Step 1: 7x-2y=-6 Step 2: 7x-2y=-6 solve by elimination of the y value

2(8x+y=3)2 +(16x+2y=6)

Step 3: 23x=0, which means <u>x=0</u>

Step 4: subtitute 0 into the equation 8x+y=3

you get 8(0)+y=3, which comes to 0+y=3

you get <u>y=3</u>

therefore the solution to this system is (0,3)

The following graph shows a proportional relationship.

MAXImum [283]

The constant of proportionality of the given graph is gotten as 4.

<h3>How to find the constant of proportionality?</h3>

The constant of proportionality here is simply the slope of the graph.

Now, we will take two points and use their coordinates to find the slope from the formula;

m = (y2 - y1)/(x2 - x1)

Let us pick 2 points which are;

(1, 4) and (2, 8). Thus;

m = (8 - 4)/(2 - 1)

m = 4/1

m = 4

Thus, the constant of proportionality of the graph is gotten as 4.

A cowboy at a dude ranch fills a horse trough that is 1.8 m long, 70 cm wide, and 35 cm deep. He uses a 2.0 cm diameter hose fro

Alexandra [31]

Answer: The time taken for the cowboy to fill in the ranch is 12.53 mins.

Step-by-step explanation:

The given parameters:

- Length of the ranch, L = 1.53 m

- Width of the ranch, w = 61 cm = 0.61 m

- Depth of the ranch, h = 42 cm = 0.42 m

- Diameter of the hose, d = 2 cm

- Radius of the hose, r = 1 cm

- Speed of the water, v = 1.66 m/s

The volume of the ranch is calculated as follows:

V = Lwh

V = 1.53 x 0.61 x 0.42

V = 0.392 m³

but all in all the time taken for the cowboy to fill the ranch is 12.53 min.

5. Marie buys 2 pounds of turkey and 1 pounds of ham. She pays a total of $20,

NARA [144]

Answer:Let t = cost per pound of turkey

Let h = cost per pound of ham

4t + 2h = 30

t = h - 1.5

substitute h-1.5 in place of t in 1st equation

4(h-1.5) + 2h = 30

4h - 6 + 2h = 30

6h - 6 = 30

6h = 36

h = 6

t = h-1.5 = 4.5

1 pound of turkey costs $4.50

1 pound of ham costs $6.00

----------

cost of 1 pound each $10.50
