Sasha uses 2 cups of vinegar to make 1 salad dressing.
Sasha wants to make 4/5 of the salad dressing.
You can multiply 4/5 by 2:
or 
Answer:
f(- 3) = 12
Step-by-step explanation:
Substitute x = - 3 into f(x) , that is
f(- 3) = (- 3)² - (- 3) = 9 + 3 = 12
Think of it as a normal linear equation first. Let's find the slope.
m = rise/run = (3-1)/(0-1) = -2
We know the slope is negative now, so we can immediately get rid of the first two answers. Now, we know that the solutions must be under the line itself, so we can try figuring it out by testing some points. Let's use (0,0).
Is 0 </> 0+3? Since it's <, then we know the last answer is correct (y < -2x + 3).
