Do the points A(1,3) B(4,2) C(-2,4) lie on the same line? Explain your answer. Show all work.
Jet001 [13]

We can see that

Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC

The given points are on same line.

Further explanation:

There are two methods to find if the given points are on same line

  • The slope method: If the points are on same line the slopes of two pairs of points will be same
  • Area of triangle method

Given points are:

A(1,3) B(4,2) C(-2,4)

We will find the slope of AB, BC, and AC

So,

m=\frac{y_2-y_1}{x_2-x_1}

Slope\ of\ AB=\frac{2-3}{4-1} \\=-\frac{1}{3}

Slope\ of\ BC=\frac{4-2}{-2-4}\\ =\frac{2}{-6}\\=-\frac{1}{3}

Slope\ of\ AC= \frac{4-3}{-2-1} \\=-\frac{1}{3}

We can see that

Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC

The given points are on same line.

The area of this rectangle is 96 ft2.<br> What is the length and width?
chubhunter [2.5K]

Answer:

length is 8

width is 12

Step-by-step explanation:

the equation to solve this would be

x*(x+4)=96

you isolate the variable by dividing each side by factors that doesn't contain the variable

X would then equal 8

length is 8

width is 8+4= 12

What are the first four terms in the sequence Tn=4n+9?
marysya [2.9K]

Answer: If the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n)/2 = n [2a 1 + (n - 1)d]/2

What is the value of x in the equation (x + 12) = (x + 14) – 3?
vodomira [7]
(x + 12) = (x + 14) - 3

subtract 12 from each side

x = x + 14 - 3 - 12

Now if we subtract x from each side we see that x - x = 0.  Combine the terms left over and we have -1, so

0 = -1

The answer is NO SOLUTION
