56 really to easy ...........
Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49

Step-by-step explanation:
Answer:
x≥8
Step-by-step explanation:
You actually don't need a graph to be able to solve this equation. As long as you are given two data points, you can already solve for the linear equation.
The most common way of writing linear equations is the slope-intercept form:
y = mx + b, where m is the slope and b is the y-intercept.
The slope is the ratio of the change of y to the change of x coordinates. Let's say point 1 is (-1,3) and point 2 is (2,-3). Then,
m = (-3-3)/(2-⁻1) = -2
Next, we use any of the given point to the standard equation along with the m to find b. Let's use (-1,3)
3 = -2(-1)+b
b = 1
Thus, the complete linear equation is y = -2x + 1. The answer is B.
