Answer:

<h3>            -2a³ + 9a² + 6ab² + 45a + 18b² </h3>

Step-by-step explanation:

(a + 3)×(−2a² + 15a + 6b²) =

= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =

= -2a³ + <u>15a²</u> + 6ab² - <u>6a²</u> + 45a + 18b² =

= -2a³ + 9a² + 6ab² + 45a + 18b²

Identify whether the function graphed has an odd or even degree and a positive or negative leading coefficient.
Shtirlitz [24]

Answer:

odd degree and positive leading coefficient

Step-by-step explanation:

From the graph , we can see that when x goes to infinity , y goes to infinity

As x--> ∞, y--> ∞ (As x increases the value of y increases on the positive side)

we can see that when x goes to -infinity , y goes to -infinity

As x--> -∞, y--> -∞ (As x decreases the value of y decreases on the negative side)

When x--> ∞, y--> ∞   and x--> -∞, y--> -∞

The leading coefficient is positive  and largest exponent is odd

So the graph has odd degree and positive leading coefficient

Find the slope, or rate of change, from the graph.
TEA [102]

Answer:

-1/2

Step-by-step explanation:

slope is rise over run

or y change divided by x change

to find the slope you need to find points on the graph that meet exact points on the graph

i see (0,1) and (2,0)

to find slope without graph it would be (y2-y1)/(x2-x1)

in this case (0-1)/(2-0)

=-1/2

with graph you can count that it goes down -1 squares and to the right 2 squares

hope this helps
