Ratio is just a fraction in other form. To create ratio we can just make fraction and transform it into ratio, so
Now we can simplify the ratio/fraction
= 4:3 - its the result
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
m(m-3)=108
Step-by-step explanation:
Complete question below:
Two positive integers are 3 units apart on a number line. Their product is 108.
Which equation can be used to solve for m, the greater integer?
m(m – 3) = 108
m(m + 3) = 108
(m + 3)(m – 3) = 108
(m – 12)(m – 9) = 108
Solution
On the number line,
Let
m= larger integer
The integers are 3 numbers apart on the number line, so
m-3=smaller integer
The product (×) of the larger and smaller integers=108
(m)*(m-3)=108
m(m-3)=108
Therefore, the equation that can be used to solve for m, the larger integer is:
m(m – 3) = 108
Answer:
No
Step-by-step explanation:
A function is an equation for which any x value matches with exactly one y value
.
x=1 matches with any y answer (as y is not included in the equation), so it is not a function.

Answer:
1. c.
2. a.
3. b.
Step-by-step explanation:
Remember f(x) = y
1. f(x) = y = 2/5x+8
2. f(x)= y - 8 = x => y = 8 +x
3. f(x) = y = x - 8
