First, convert that into a y=mx+b form.

Move the x to the other side so y is the only thing on the left. Since you moved it to the other side of the equal sign, be sure to make that number negative (the opposite sign)

Now… you have 4y=-3x+28
Let’s get y by itself. Since you’re multiplying 4 and y, you divide everything by 4 to get your y.

That leaves you with y=-3/4x+7.

We are looking at slope, which is your m in the y=mx+b form.

That is -3/4. The answer is the last square.

Answer:

notice: temperature rises quickly at sunrise, and drops before sunset
wonder: whether this location is shaded by mountains later in the day

Step-by-step explanation:

<u>notice</u>

The temperature starts off below zero in the early morning and stays cold until the sun comes up. Then it warms rapidly to an above zero temperature that peaks in early afternoon. Once the sun gets lower, the temperature starts cooling off again. (The daily temperature range of 25-27 degrees is pretty typical for partly-cloudy sky conditions and stable weather.)

<u>wonder</u>

We wonder if this isn't a location that is on the east- or north-side of a mountain, or in a mountain valley, where the sun hits it early and is shaded later in the day. (The topo map attached seems to show it is in such a location.)

Answer:

0.77

Step-by-step explanation:

From the information given:

The breakdown time (a)= 3 hours

The breakdown rate (λ) = 1/a = 1/3

Average flow time in the system (W) = 2.305 hours

For the entire system;

The average down machines L = Wλ

= 2.305 × (1/3)

= 0.77

I walked for 2 1/2 hours at 4km/h and for 4 hours at 2 1/2 km/h. What was the average speed for the entire journey?

Murrr4er [49]

Average speed of the entire journey is 3.08 km/hr

Step-by-step explanation:

Step 1: In the first half, given that the speed = 4 km/h and time = 2 1/2 = 2.5 hrs. Calculate the distance covered.

Distance = Speed × Time = 4 × 2.5 = 10 km

Step 2: In the second half, given that speed = 2 1/2 = 2.5 km/hr and time = 4 hrs. Calculate the distance covered.

Distance = 2.5 × 4 = 10 km

Step 3: Calculate average speed.

Average Speed = Total distance/Total time

= 10 + 10/2.5 + 4 = 20/6.5

= 3.08 km/hr

Joel has 8 white golf balls and 7 orange golf balls in a bag. If he removes an orange golf ball and does NOT return it to the ba

Alborosie

Answer:

57.14%

Step-by-step explanation:

So if he removes an orange ball from the bag, that means there are 8 white golf balls and 6 orange golf balls - 14 balls in total

8 balls of the 14 are white, so to find the percent we can set up a proportion

8/14=x/100

you can simplify 8/14 to 4/7

4/7=x/100

cross multiply

7x=400

divide by 7 on both sides

x=57.14%
