Answer:

y=\frac{3}{4}x+2

Step-by-step explanation:

So when you express a linear function in slope-intercept form it's given in the form of y=mx+b, where m is the slope, and b is the y-intercept. This is because as x increases by 1, the y-value will increase by m (because multiplication), and since the slope is defined as rise/run, the rise will be m, and run will be 1, giving you a slope of m/1 or m. The reason b is the y-intercept, is because whenever the linear function crosses the y-axis, the x-value will always be 0. Meaning that mx will be 0 because m * 0 will equal 0... and that leaves b by it self, so b will determine the y-intercept.

So if you look at the graph, the linear function crosses the y-axis as (0, 2) so the value of b will be 2. This gives you the equation y=mx+2.

Now to calculate the slope, we can take any two points and see how much the rise was and how much the run was. It can also be more formally defined in the equation: y=\frac{y_2-y_1}{x_2-x_1}. So let's take the points (0, 2) and (8, 8). As you can see the x-value increases by 8 or "ran" by 8, and the y-value increased by 6. So the rise over run in this case is 6/8 which can simplified as 3/4. That is the slope. This gives you the complete equation of: y=\frac{3}{4}x+2

3. A new bag of golf tees contains 10 red tees, 10
maw [93]

Answer: 0.2308

Step-by-step explanation:

A new bag of golf tees contains 10 red tees,10 orange, 10 green tees, and 10 blue tees. You empty the tees into your golf bags.What is the probability of grabbing out two tees of the same color in a row for you and your partner?

# of ways to succeed:: 4(10C2) = 4*45 = 180 ways

# of random pairs:: 40C2 = 780

P(2 of same color) = 180/780 = 0.2308

Therefore your answer is 0.2308

I hope this helps! :)

<u>Answer (1):</u>

Coefficient of any term  means the number multiplied in that term including sign.

ab^2 is same as 1ab^2.

Hence required coefficient is 1.



<u>Answer (2):</u>

4(3-7)^2+102


=4(-4)^2+102


=4(16)+102


=64+102


=166


Hence final answer is 166


<u>Answer (3):</u>

\sqrt{\frac{49}{25}}


=\frac{\sqrt{49}}{\sqrt{25}}


=\frac{7}{5}


Hence final answer is \frac{7}{5}
