For funcitons f(x)=2x+3 and g(x)=-3x-2, please find (f∘g)(-1)

ratelena [41]

Answer:

$\displaystyle (f\circ g)(-1) = 5$

Step-by-step explanation:

We are given the two functions:
$\displaystyle f(x) = 2x + 3\text{ and } g(x) = -3x - 2$

And we want to find:
$\displaystyle (f\circ g)(-1)$

Recall that this is equivalent to:
$\displaystyle (f\circ g)(-1) = f(g(-1))$

Hence, find g(-1):
$\displaystyle \begin{aligned} g(x) & = -3x - 2\\ \\ g(-1) & = -3(-1) - 2\\ \\ & = (3) - 2 \\ \\ & = 1 \end{aligned}$

Substitute:
$\displaystyle f(g(-1)) = f(1)$

Find f(1):

$\displaystyle \begin{aligned} f(x) & = 2x+ 3 \\ \\ f(1) & = 2(1) + 3 \\ \\ & = 5\end{aligned}$

In conclusion:
$\displaystyle (f\circ g)(-1) = 5$

Answer:

x = 24 , y = 19

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

2x - 8 = x + 16 ( subtract x from both sides )

x - 8 = 16 ( add 8 to both sides )

x = 24

and

2y = y + 19 ( subtract y from both sides )

y = 19

At the school Halloween dance. 85% of the students were present. If there are 765 students at the dance then how many total stud

marishachu [46]

Answer:

900 students

Step-by-step explanation:

We have, 85% × x = 765 or, 85/100 × x = 765. Multiplying both sides by 100 and dividing both sides by 85, we have x = 765 × 100/85. So x = 900. If you are using a calculator, simply enter 765×100÷85, which will give you the answer.
