How can help me with this operation about Pre-Calculus. Simplify

Mrrafil [7]

If we want to compute $f(2+h)$ , we have to substitute every occurrence of $x$ with $2+h$ in the definition of the function:

$f(x)=x^2-11x \implies f(2+h) = (2+h)^2-11(2+h) = 4+4h+h^2-22-11h = h^2-7h-18$

Similarly, computing $f(2)$ means to substitute the input with 2:

$f(x)=x^2-11x \implies f(2) = 2^2-11\cdot 2 = 4-22 = -18$

So, we have

$f(2+h) - f(2) = h^2-7h-18 - (-18) = h^2-7h$

And finally

$\dfrac{f(2+h)-f(2)}{h} = \dfrac{h^2-7h}{h} = h-7$

3 2/5 time 5. Show work

xenn [34]

let's firstly convert the mixed fraction to improper fraction and then multiply.

$\bf \stackrel{mixed}{3\frac{2}{5}}\implies \cfrac{3\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{17}{5}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{17}{~~\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\cdot ~~\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~\implies 17$

NEED ASAP WILL GIVE BRAINLIEST Write a real world problem that can be represented by the following inequality, 15X - 20 ≤ 130 ,a

ddd [48]

Answer:

I used my name, lol

Step-by-step explanation:

Kat wants to use her money to support animals at a shelter after receiving her pay check from work . She pays $15 per animal, and leaves $20 for the workers. She can spend at most $130. How many animals can she help?

Solve for x

$15x-20\leq 130$

Add 20 to both sides to isolate x

$15x-20+20\leq 130+20\\15x\leq 150$

Divide each side by 15

$\frac{15x}{15}\leq \frac{150}{15} \\\\x\leq 10$

Kat can help at most 10 animals.

(I am so sorry I took so long, I couldn't come up with anything.)

How can you use properties of multiplication to determine what the factors are

aleksandrvk [35]

Factors can be multiplied together to get the original number.

For example here are the factors of 66.

1 and 66. 2 and 33. 3 and 22. 6 and 11.

1 multiplied by 66 results in the original number 66.

2 multiplied by 33 results in the original number 66.

3 multiplied by 22 results in the original number 66.

6 multiplied by 11 results in the original number 66.
