Answer:is

=x(x-4)-45

Step-by-step explanation:q= (x+5) (x-9)

in the mathematical rules when the variables are in the brackets it means we have to remove the brackets by,multiplying the first variable to the second variable in another bracket, and then so on.

=x^2-9x+5x-45

=x^2-4x-45

by simplifying completely it will become,

=x(x-4) -45

that's the answer.

Find the 10th term of the arithmetic sequence with the terms a1=15 and d=80

Alchen [17]

Answer:

The 10th term is 735

Step-by-step explanation:

The 10th term of an Arithmetic Sequence is given by:

$a_{10}=a_1+9d$

From the question, we were given that:

$a_{1}=15$

and

$d = 80$

We substitute these values into the above expresion to obtain:

$a_{10}=15+9 \times 80$

$a_{10}=15+720$

$a_{10} = 735$

How does the graph of g (x) = StartFraction 1 Over x + 4 EndFraction minus 6 compare to the graph of the parent function f (x) =

rjkz [21]

The transformed equation $g(x)=\frac{1}{x+4}-6$ , the graph is shifted 4 units to the left and 6 units down.

Explanation:

The parent equation is $f(x)=\frac{1}{x}$

The transformed equation is $g(x)=\frac{1}{x+4}-6$

By using the function transformation rules, we can see that the parent function $f(x)=\frac{1}{x}$ is transformed into the function $g(x)=\frac{1}{x+4}-6$

Since, from the function transformation rules, we know that,

$f(x+b)$ shifts the function b units to the left.

Thus, the transformed function is shifted 4 units to the left.

Also, from the function transformation rules, we know that,

$f(x)-b$ shifts the function b units downward.

Thus, the transformed function is shifted 6 units down.

Thus, the transformed equation $g(x)=\frac{1}{x+4}-6$ , the graph is shifted 4 units to the left and 6 units down.
