Hello!
To find the line perpendicular to the given line, y = 2x + 3, firstly, find the slope of the perpendicular line. To find it, use this format: -1/m, where m is the slope. It is also called the "negative reciprocal" of the slope of the given line.
Then, you substitute an ordered pair into a new slope-intercept equation (with the slope) and find the y-intercept.
-1/m when m = 2 → -1/2
y = -1/2x + b (substitute the given ordered pair)
-3 = -1/2(2) + b (simplify)
-3 = -1 + b (add 1 to both sides)
-2 = b | The y-intercept of the perpendicular equation is -2.
Therefore, the line perpendicular to the given equation, that also goes through the given ordered pair is y = -1/2x - 2.
Answer:
13 is the answer.
Step-by-step explanation:
Answer:
38 1/2 meters
Step-by-step explanation:
You have to multiply 28× 1 3/8
You can convert yhe 1 3/8 to an improper fraction, then multiply, and convert back to a mixed number. See image.
OR,
you can distribute the 28 over the sum of 1 and 3/8. This just keeps the fraction a little bit smaller and you can practice distributive property see image
Answer:
b) 13
c) 37
Step-by-step explanation:
b) 2 + 5 + 6 = 13
c) 3 + 2 + 5 + 6 + 8 + 8 + 4 + 1 = 37
hope this helps
