Answer:
2x-6
Step-by-step explanation:
You can rewrite this problem into an equation. You know that the ratio of boys to girls is 4 to 3, which is the same as:
Cross multiply to get to 4G = 3B
Divide both sides by 4, to isolate the G (# of girls).
G = 3B / 4 = 0.75B
So you know that B + G = 35 (boys plus girls equals 35). Replace the G in this equation with the one you found above so that the entire equation only has one variable.
B + G = 35
B + 0.75B = 35
1.75B = 35
1.75B / 1.75 = 35 / 1.75
B = 20
However, you need to find G. So plug B back into one of the equations:
B + G = 35
20 + G = 35
G = 15
Answer: y =
Step-by-step explanation:
We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.
We could find the points (0,-3) and another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.
(0,-3)
(3,-2)
y -3 - (-2) = -1
x 0 - 3 = -3
-1/-3 = 1/3
so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3
so the equation will be y = 1/3x - 3
