Answer:
a = 5
Step-by-step explanation:
a +a+4 + 2a-3 = 21
4a +1 =21
4a = 20
a = 5
Where is the graph or picture?
12. 500=2^2 * 5^3
13. 7-2*9=-11
14. 225-5*16+5=230-80=150
15. |1/3 * (8-20)|= 4
16. 3/2* ( 64-4*9)= 3/2*28=3*14=42
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.
