I need to find the area, what is it?

Answers

Answer:

.75

Step-by-step explanation:

You have to do B * H / 2 which 1.5 x 1 = 1.5, and then 1.5/2 = .75

In order to find the area of a triangle, you must do 1/2 base x height.

So to plug in the numbers, you will have 1/2 x 1 x 1.5.

1/2 x 1 = 0.5 and 0.5 x 1.5 = 0.75

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.

*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)

Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7

I hope this is the right answer!

2 3/10= 2.3

2. 3(2x + 9)

Answers

Answer:

1. 56x 35x

what you had to do was add 42 plus 14x which gives you 56x. then for number two you had to multiply the numbers inside of the parenthesis by the number outside of the parenthesis which will give you 35x.

I’m not sure but, I think the second one is 6x+27. I don’t think you can’t simplify the first one, if that’s what your asking. But, if your asking what x is, please tell me and I’ll do that instead.

A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false?

Select the correct choice for each statement then explain your reasoning.

1. Speed is a function of time.
2. Time is a function of distance.
3. Speed is a function of number of students racing.
4. Time is a function of speed.

Answers

Answer:

The true statements are (a) and (d)

Step-by-step explanation:

(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.

(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.

(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.

(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.

The true statements are (a) and (d).

The true statement are (a) and (b)
