Answer:
y= 4x -6
Step-by-step explanation:
you write the equation by finding the y-intercept (what y is when x is 0) and then find the slope. slope is rise/run (or y-value over x-value) so you count how you get from the first number of the table, to the second number (for both top and bottom) with the x-values they go up by 1 every time, and with the y-values they go up by 4 every time. so put it as rise/run which would be 4/1 and then simplify, so it's 4. and then you plug the slope and y-intercept into the equation y=mx+b (m is slope and b is y-intercept) and you get: y=4x-6
1. (false) A chord is never a radius. A chord is the line segment whose 2 endpoints are points on the circle.
2. (true) A diameter is always a chord, in fact, it is the chord of largest length.
3. (true) A tangent is a line in the exterior of a circle, with only 1 common point with a circle. Whereas a secant has 2 common point with a circle and many more in the interior of the circle
4. (false) A chord can be at most equal to the length of the diameter.
5. (true) A chord can be very short. Consider 2 points on the circle which are very close to each other and the chord formed by them.
6. (true)
Answer:
if im correct i think the answer is y=1.25x-0.5

The image below shows the equation x - 2y = 6 being graphed.
Hope this helps! :)
A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)
So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.
P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)
