Answer:

8 hours

Step-by-step explanation:

total labor hours required

12 * 6 = 72

hours per worker with 9 workers

Are two lines with positive slopes parallel?

frosja888 [35]

Answer:

Not necessarily, but they could be.

Step-by-step explanation:

The only time two lines are parallel is if they have the exact same slope. Since both are positive here, that could be true. However, if they differ even the slightest bit, than no, they would not be parallel.

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the so

OleMash [197]

The point of intersection of two given equations is (0.333, 2.667).

Given that, equation with two variables are y = 8x and y = 2x + 2.

The given equations will intersect at some point where y is the same for both equations.

When you replace y in y = 2x + 2 with y = 8x, we get 8x = 2x + 2.

So, the solution of 8x = 2x+2 will satisfy both equations.

Now, we need to find the solutions to take the integer values of x between -3 and 3.

That is,

x = -3 , then 8(-3) = 2(-3) +2⇒-24 = -6+2

⇒-12 = -4 False.

similarly, for x = -2

8(-2) = 2(-2)+2

⇒-16 = -2 False

For, x = -1

8(-1) = 2(-1)+2

⇒-8= 0 False

For, x = 0

8(0) = 2(0)+2

⇒0= 2 False

For, x = 1

8(1) = 2(1)+2

⇒8= 4 False

For, x = 2

8(2) = 2(2)+2

⇒16 = 6 False

For, x = 3

8(3) = 2(3)+2

⇒24 = 8 False

Therefore, there is no solution to 8x = 2x +2 for the integers values of x between -3 and 3.

The equations can be solved graphically by plotting the two given functions on a coordinate plane and identifying the point of intersection of the two graphs.

The point of intersection is the values of the variables which satisfy both equations at a particular point.

Hence, you can see the graph as shown below, the point of intersection is (0.333, 2.667).

Brilliant_brown [7]

Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .

<u>Step-by-step explanation:</u>

Here we have , Bruce saved $ 35.00 to buy a new video game. The game's original price was $ 42.00 , but it was on sale for 30% off. The sales tax rate was 5%. We need to find Did Bruce have enough money to buy the game .Let's find out:

We have , Bruce saved $ 35.00 to buy a new video game . The game's original price was $ 42.00 , but it was on sale for 30% off. i.e.

Price = $Original price - \frac{Original-price(30)}{100}$

⇒ $42-\frac{42(30)}{100}$

⇒ $42-\frac{1260}{100}$

⇒ $42-12.6$

⇒ $29.4$

Now, The sales tax rate was 5%. So , total amount to be paid is :

⇒ $29.4 + \frac{29.4(5)}{100}$

⇒ $29.40 +1.47$

⇒ $30.87$

Bruce have $35 which is greater than amount to be paid i.e. $30.87 . So , Bruce have enough money to buy the game .
