The first expression can be simplified by combining like terms.

First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"

Finally, we simply put these two final terms together, to form "b+2"

Hence, 4b-7-3b+9 is equal to be + 2.

Hope this helps!

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

Determine if the following statement is true or false.
Alla [95]

Answer:

A. True

Step-by-step explanation:

The general formula for predicting an outcome in a binomial probability distribution function is: nCx(p)^x(q)^(n-x)

where p is the probability of success and q is the probability of failure

From the above formula; nCx represent the number of ways of obtaining x successes in n trials.

nCx is a combination computation and combination helps to determine in how many ways a certain outcome is possible.

What is the slope of the line in the graph?
Viktor [21]

Answer:

The slope of the line in the graph is 1.

Step-by-step explanation:

Slope is determined by rise over run. Meaning that the number of units the slope goes up/down divided by the number of units the slope goes to the left/right is the slope. The rise is one, and the run is one. 1 over 1 equals 1.
