Find length of each side
IgorLugansk [536]

Option b: 10 in, 18.5 in, 31.5 in.

Explanation:

The three sides of a triangle are 2y+1, 3y+5 and 7y

The perimeter of the triangle is 60 in.

Since, Perimeter = all sides of the triangle

Let us add all the three sides to determine the length of each side.

Perimeter=2y+1+3y+5+7y

Substituting the value of Perimeter and simplifying, we get,

60=12y+6\\54=12y\\4.5=y

Substituting y=4.5 in the three sides of the triangle 2y+1, 3y+5 and 7y, we get,

2y+1=2(4.5)+1=10 in

3y+5=3(4.5)+5=18.5 in

7y=7(4.5)=31.5 in

Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.

Find the slope of the line that passes through the two points below.<br> (3,4) and (3,-1)
tangare [24]

Answer:

Slope = (-5,0)

Step-by-step explanation:

When given two points and asked to find the slope, you can find the answer using slope formula which is:

slope = (y2 - y1) / (x2-x1)

You have been given the points (3,4) and (3,-1). You can select which ones to be x1 and y1 and which ones to be x2 and y2. It doesn't matter which, so let's just do (3,4) are x1 and y1 and (3,-1) are x2 and y2. Now we can plug it into the formula.

Slope = (-1 - 4) / (3-3)

= -5 / 0

= -5,0

So the answer is (-5,0).
