Answer:
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: where <em>m</em> is the slope and <em>b</em> is the y-intercept.
Perpendicular lines always have slopes that are negative reciprocals (ex. 1/2 and -2, 3/4 and -4/3)
<u>Determine the slope (</u><em><u>m</u></em><u>):</u>
Rearrange into slope-intercept form:
Now, we can identify clearly that the slope is -2. Because perpendicular lines always have slopes that are negative reciprocals, a perpendicular line would have a slope of . Plug this into :
<u>Determine the y-intercept (</u><em><u>b</u></em><u>):</u>
Plug in the given point (1,3) and solve for <em>b</em>:
Therefore, the y-intercept is . Plug this back into :
I hope this helps!
Answer: Equilateral Triangles
Step-by-step explanation: Let x = the degree measure of each angle. Triangles have three angles and so we will add x THREE times. Makes sense, right? If all the angles are equal, and they add up to 180, then it has to be 60 degrees!
Answer:
31200 m
Step-by-step explanation:
120 times 60 equals 7200 and 200 times 120 equals 24000 and add the two up you get 31200
Hi!
okay say you have the fractions 1/4 and 6/24, these two fractions are equivalent because you can multiply the numerator and the denominator by 6 to get 6/24 (1x6 = 6 and 4x6 = 24).
similarly you can reduce 6/24 to 1/4 by dividing the numerator and denominator by 6 (6/6 = 1 and 24/6 = 4).
i hope this helped!
Answer:
4.06 inches, or about 4 inches.
Step-by-step explanation:
The value of pi is a <em>circle's circumference divided by its diameter</em>.
Here, the equation is <em>40.6 ÷ 10</em>.
The quotient of 40.6/10 is 4.06 inches.
I assume the approximate value will be among the range of <em>4 inches through 4.1 inches</em>.
