Answer:
(f⋅g)(x)=8x^2−2x−15
Step-by-step explanation:
To find the expression (f*g)(x), multiply f(x) into g(x) using the distribution property.
(f*g)(x) = (2x - 3)(4x + 5) = 8x² - 12x + 10x - 15 = 8x² - 2x - 15
Answer:
7-4= 3
one-third of 9 is 3
so the answer would be one-third of 9
Step-by-step explanation:
one-third of 9 is 3
3+4=7
N>8 but with the little line underneath.
So choice two
Answer:
Step-by-step explanation:
It would be X=2 because axis of symmetry is the line passing through X=2.
Let's look at our equation,
<span>p÷7
We must look at all our options before selecting one of them.
Can the answer be A?
</span><span>Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.
</span><span>
No that would not work,
We would have subtraction. It would look like this.
p-7.
How about B?
</span><span>Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span><span>
That would actually work. This is how our equation would look.
p</span>÷7.
<span>It matches the expression.
Before we make that our final answer, we should check everything else.
Here is C
</span><span>C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.
</span>
That would not work.
How about D?
<span>D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.
</span>
D is also incorrect. It would not work at all.
That means our final answer is:
<span>B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span>
I hope that helped! :)
