Complete the equation of the line whose y intercept is (0, 6) and the slope is 3

Answers

Answer:

y=3x+6

Step-by-step explanation:

The slope form can be written as y=mx+b

m is the slope, which is 3 in this case.

b is the y-intercept (6).  

Add those values into the slope form equation.  Just leave y as is.

It’s y=3x+6 because if you solve for the y-intercept by doing 6=3(0)+b you’ll get b=6. Then you just plug in the m values and the b and you’ll get y=3x+6

A cyclist rode 3.75 miles in 0.3 hours.

How fast was she going in miles per hour?
At that rate, how long will it take her to go 4.5 miles?

Answers

Answer:

1)speed=12.5 miles/hr

2)time=56.25hr or 0.36hr(i prefer this one..check explanation)

Step-by-step explanation:

speed=distance/time

s=3.75/0.3=12.5

speed is = 12.5 miles/hr

2nd part:

speed=distance/time

so time=speed*distance

: time=12.5*4.5=56.25hr(hard to believe the answer)

or

miles:hours

3.75:0.3

4.5:x

cross multiply

4.5*0.3/3.75=0.36

x=0.36hrs (answer is believeable)

Answers

Answer:

I think what you would have to do is use the formula m= y1 - y2/ x1 - x2 so you can find the slope of any two points on the graph and then to get the equal value of both of them you will have to multiply or add, but I am not sure. If they are different measurements you will have to convert.

A farmer has 96 apples to sell at the farmers market. She wants to bag the apples before going. How many ways can the farmer bag the apples so that: each bag has at least 4 apples each bag has no more than 10 apples all bags have the same number of apples

Answers

Answer and explanation:

Farmer's number of apples = 96 apples

Given that Farmer needs to bag the apples so that there are at least 4 apples in each bag(not less than 4 apples in each bag) and not more than 10 apples in each bag

And also all apples in each bag are equal

We need to find the numbers between 4 and 10(including 4 and 10) that can divide 96 without a remainder

4 can divide 96= 24

5 cannot divide 96 without remainder

6 can divide 96 =16

7 cannot divide 96 without remainder

8 can divide 96=12

9 cannot divide 96 without remainder

10 cannot divide 96 without remainder

From the above we see that the factors of 96 = 4, 6, 8 between 4 and 10

4 apples = 24 bags

6 apples = 16 bags

8 apples = 12 bags

Therefore, there can be 3 possible ways of having equal number of apples in each bag between 4 and 10 apples
