Answer:
y = -7/2 + 5x/2
t = 3k/v
f = 9c/5 +32
Step-by-step explanation:
The answer is b) y = 3x + 3.
To find this, we first need to find the slope. The slope formula is listed below.
m = (y2 - y1)/(x2 - x1)
In this equation, m is the slope, and (x1, y1) is the first point, where (x2, y2) is the second point. We'll use (2, 9) and (3, 12) for the points.
m = (y2 - y1)/(x2 - x1)
m = (12 - 9)/(3 - 2)
m = 3/1
m = 3
Now that we have the slope at 3. we can use slope intercept form and one point to solve for the y-intercept. We'll use (2, 9) as the point.
y = mx + b
9 = 3(2) + b
9 = 6 + b
3 = b
When we use the slope and intercept together to get the equation. y = 3x + 3
Hello!
For every 1 blue marble there are 5 greens
You add the numbers in the ratio
1 + 5 = 6
Divide this number from the amount of marbles
60 / 6 = 10
Multiply the ratio by this
1 * 10 = 10
5 * 10 = 50
There are 10 blue marbles and 50 green ones
The answer is 10
Hope this helps!
