Answer:
"a" must be negative
Step-by-step explanation:
The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.
The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.
Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.
By the size , color, or if they have wings or no wings, etc. just think of what might be different on each one or group.
Answer:
7*7*7*7
Step-by-step explanation:
=> 
<u><em>This means that 7 is multiplied 4 times</em></u>
So, it becomes:
=> (7×7×7×7)
R² - 6r - 8 = 0
r² = 7.12
r = -1.12
