The graph represents function 1, and the equation represents function 2: Function 1 A coordinate plane graph is shown. A horizon

Katena32 [7]

The horizontal line at y=4 doesn't have any slope, so the answer should be relatively easy to find. It's just the slope of Function 2.

y = 8x + 12 is the function for Function 2. 8x is the important part.

So the rate of change differing from both functions is 8.

at the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. three cheeseburgers and two

qwelly [4]

Answer:

There are 230 calories in each cheeseburger and 290 calories in each small fries.

Step-by-step explanation:

Let us assume:

The calories in each cheeseburger = x

The calories in each small fries = y

So, the calories in 4 cheeseburger

=4 (calories in 1 cheeseburger ) = 4 x

and the calories in 5 small fries = 5(calories in 1 small fries ) =5 y

⇒ 4 x + 5 y = 2310

Similarly, calories in 3 cheeseburger

= 3 ( calories in 1 cheeseburger ) = 3 x

and the calories in 2 small fries = 2 (calories in 1 small fries )= 2 y

⇒ 3 x + 2 y = 1330

Solving the given system of equation:

4 x + 5 y = 2310 ............(1)

3 x + 2 y = 1330 ............. (2)

Multiply equation (1) with (-3) , and (2) by 4 and add both equation.

-12 x - 15 y + 12 x + 8 y = -6930 + 5320

or, - 7 y = -1610

⇒ y = 1610 / 7 = 230 , or y = 230

Putting this in (2) , we get 3 x + 2 y = 1330

⇒ 3 x + 2(230) = 1330 or, 3 x = 1330 - 460 = 870

or, x = 870/3 = 290

⇒ x = 290

Hence, there are 230 calories in each cheeseburger.

There are 290 calories in each small fries.

Find the area of a circle with a diameter of 12 in. Rounded to the nearest whole

zheka24 [161]

Answer:

113.04

Step-by-step explanation:

To find the area of a circle, you multiply 3.14 times the radius squared. To find the radius, you divided the diameter by 2. You get 6. You square 6 and get 36. Multiply that by 3.14 and you'll get 113.04 as your area.

Answer:

2/7

Step-by-step explanation:

The quotient is ...

$\dfrac{-16}{-56}=\dfrac{2\cdot8}{7\cdot8}=\boxed{\dfrac{2}{7}}$

A common factor of -8 can be cancelled from numerator and denominator.

The davis family traveled 35 miles in 1/2 hour if it is currently 2:00pm any the family destination is 245 miles away at what ti

xxMikexx [17]

The distance traveled by Davis family = 35 miles

Time taken to cover the distance = $\frac{1}{2}$ hour

Speed = Distance $\div$ Time

Speed = $35 \div \frac{1}{2}$

Speed = $35 \times 2$

So, speed = 70 miles/hour.

At 2:00 pm, the family destination was 245 miles away.

So, the number of hours, when the family was 245 miles away = $245 \div 70$

= 3.5 hours

So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.
