Select the equations of f the lines that are parallel to the lines whose equations is y=3x+5
saw5 [17]

Answer:

<h2>y = 3x + b where b is any real number</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the equation: y=3x+5

Parallel lines have the same slope. Therefore the equation of the lines that are parallel to the given line if in form:

y=3x+b

where b is any real number.

Write a simplified expression that represents the perimeter of an irregular quadrilateral with some de lengths (2 1/4t - 5) (4t
hjlf

Answer:

Perimeter = \frac{39t-4}{4}

Step-by-step explanation:

Given

Lengths: (2\frac{1}{4}t - 5), (4t + 3), (1/2t - 1), (3t + 2)

Required

Determine the perimeter

The perimeter is calculated as the sum of the lengths of the irregular shape.

i.e.

Perimeter = (2\frac{1}{4}t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)

Remove brackets

Perimeter = 2\frac{1}{4}t - 5 + 4t + 3 + 1/2t - 1 + 3t + 2

Collect Like Terms

Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t - 5 + 3 - 1 + 2

Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t -1

Convert mixed number to improper fraction.

Perimeter = \frac{9}{4}t +4t + 1/2t + 3t -1

Take LCM

Perimeter = \frac{9t + 16t + 2t + 12t}{4} -1

Perimeter = \frac{39t}{4} -1

Take LCM

Perimeter = \frac{39t-4}{4}  <em>--- The perimeter of the shape</em>

The distance between points (3,7) and (x1-y1) is the square root of (x1-3)2+(y1-7)2
galben [10]

Answer:

True

Step-by-step explanation:

In analytical geometry, you can find the distance between two points situated on the same plane using the distance formula. The equation is

d = √[(x2-x1)^2+(y2-y1)^2]

This can be applied by first applying which is point 1 or point 2. Technically, it does not matter which is which, as long as you are consistent in pairing of the x,y coordinates. In this case, point 1 is (3,7) and point 2 is (x1,y1). Therefore, when you substitute the values, the distance would be 

d = √[(x1-3)^2+(y1-7)^2]

The statement is TRUE.

I hope this helped. I am not sure it did. But I hope it helped you. I hope you get the question right. And I am sorry if you get the question wrong.
