Well in the equation y = mx+b, m is the slope and b is the y intercept.
So you'd have to figure out the rate of change or the slope which is x over y.
And the y intercept is just where ever the line crosses the y axis.

Hope this makes sense. Let me know if you need any more help :)

Answer:

Given that the question rightly asks the amount it cost to drive from Smithville to Jones City, we have;

The question rightly asks the amount it cost to drive from Smithville to Jones City is approximately $7.209

Step-by-step explanation:

The coordinates of Smithville is (-25, 10)

The coordinates of Jones City is (15, 12)

The cost of driving a car for a mile = $0.18

Therefore, the distance from Smithville to Jones City is given by the formula for the distance, l, between two points with coordinates as follows;

$l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}$

Where;

(x₁, y₁) = (-25, 10) and (x₂, y₂) = (15, 12)

$l = \sqrt{\left (12-10 \right )^{2}+\left (15-(-25) \right )^{2}} = 2 \cdot \sqrt{401}$

The distance from Smithville to Jones City = 2·√401 ≈ 40.05 miles

The amount, A, it cost to drive from Smithville to Jones City a distance of approximately 40.05 miles is therefore given as follows;

A = 40.05 miles × $0.18 ≈ $7.209

Let the graph of f(x) represent the cost in thousands of dollars to feed the zoo animals daily, where x is the number of animals

pickupchik [31]

Answer:

<u>There are 200 animals, and the cost is $8,000 daily</u>

Step-by-step explanation:

y=f(x) represents the cost in thousands

x is the number of animals measured in hundreds

so the point (2,8) means

x = 2

y = f(2) = 8

so it means for 2*100=200 animals, the cost is 8*1000=8 000

The correct answer is then

There are 200 animals, and the cost is $8,000 daily

hope this helps

Lizzie bought 0.8 kg of pears at €1.90 per kilogram and 1.4 kg of apples. The total cost €4.46. What was the price per kilogram

scoundrel [369]

Answer:

The the cost of 1 kg apples = € 2.1

Step-by-step explanation:

The amount of pears bought by Lizzie = 0.8 kg

The amount of apple bought by Lizzie = 1.4 kg

Total amount paid = €4.46

Now, the cost of 1 kg pears = €1.90 per kg

So, the cost of 0.8 kg pears = 0.8 x (1.90) = €1.52

Now, let the cost of 1 kg apples = € m

So, the cost of 1.4 kg apples = 1.4 x ( € m) = 1.4 m

So, the total amount = Cost of Apples + Cost of Pears

⇒ €4.46 = €1.52 + 1.4 m

or, 1.4 m = 4.46 - 1.52 = 2.94

⇒ m = 2.94/1.4 = 2.1

or, m = 2.1

Hence, the the cost of 1 kg apples = € 2.1
