Answer:

Step-by-step explanation:

y = mx + b

Take any two points and set up 2 equations with 2 unknowns.

I'll start with the first two

y = 4x + b

410 = 4x + b (1)

440 = 6x + b (2)

Subtract (1) from (2)

440 = 6x + b

<u>410 = 4x + b</u> Subtract

30 = 2x Divide by 2

30/2 = 2x/2

x = 15

440 = 6(x) + b

440 = 6*15 + b

440 = 90 + b

b = 350

Now here is what you found.

Her base salary is 350 dollars

Each television she sells brings her an addition 15.

oscar‘s Daphnis house was shaped like a tent. The slanted sides are both 5 feet long and the bottom of the house is 6 feet acros

defon

Answer:

4ft.

Step-by-step explanation:

So, due to the shape being a triangle you could split the triangle in two to determine the height. This means that its essentially two right angle triangles beside one another with the hypotenuse being 5 ft long and its base being 3ft long. ( because we split the base by 2 so 6/2=3) Now we can perform the pythagorem theorum to solve for the wanted side (height). The pythagorem theorum is the hyptenuse squared equals one side squared plus the other side squared but considering we do not have one of those sides (height) we must re-organize the formula. SO the formula we will be using is hypotenuse squared minus side squared equals height squared.

Therefore,

5(squared) - 3(squared) = x(squared)

25-9=x(squared)

16=x(squared)

square root of 16=x

4=x

Finally, state your results... so we could say that due to our results the height of the tent would be 4 ft long.

Chaz is a 79.2 pound dog that was just adopted. Based on his foster home his daily energy intake is 1,840 kcal. Chaz’s new owner

zimovet [89]

Answer:

option (c)5 and $\frac{\textup{1}}{\textup{4}}$ cups

Step-by-step explanation:

Given:

Weight of Chaz = 79.2 pounds

Daily energy intake requirement = 1,840 kcal

Energy present in different brand food = 3,523 kcal/kg

Therefore,

the amount of food required = $\frac{\textup{Daily energy intake requirement}}{\textup{Energy present in different brand food}}$

the amount of food required = $\frac{\textup{1,840}}{\textup{3,523}}$

the amount of food required = 0.52228 kg

also,

1 kg = 1000 grams

therefore,

the amount of food required = 0.52228 × 1000 = 522.28 grams

now,

A cup of food weighs 100 grams

hence,

the number of cups required = $\frac{\textup{the amount of food required }}{\textup{Amount of food per cup}}$

the number of cups required = $\frac{\textup{522.28}}{\textup{100}}$

the number of cups required = 5.2228 ≈ 5 and $\frac{\textup{1}}{\textup{4}}$ cups

Hence, the correct answer is option (c)
