Y=2x+6
gradient is found from the formula,
y intercept is found by subbing the values of (-1,4) into the equation y=2x+c
Answer:
(verify - make sure or demonstrate that (something) is true, accurate, or justified)
Answer
In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
Step-by-step explanation:
Is this a right triangle or not? If it's a right triangle, you could use the Pythagorean Theorem to find the length of the 3rd side, which would be the hypotenuse. Thus, 14^2 + 4^2 = c^2, where c is the length of the hypot.
Then 196 + 16 = 212, and this is c^2. Then c, the length of the hypotenuse, is sqrt 212, or approx. 14.6 inches.
This does not agree with any of the four possible answers. Thus, you must look at each of these possible answers and eliminate any that could not be correct.
for example: if you take 10 inches and add 4 inches, you get 14 inches. The result would not be a triangle, but rather a straight line.

Answer:
Diameter of the circle is twice it's radius D=2r.
Circumference of the circle is 2πr.
According to the above problem,
<u>2π(radius)</u>=20 inches
2(radius)=20/π=20/3.14
Diameter=<u>6.37 inches</u>
<h3><u>6.37 inches</u> is the right answer.</h3>
