Answer:

t=-3.7

Step-by-step explanation:

5 (t+3)=-3.5

solving the bracket we have;

5t+15=-3.5

collect like terms

5t=-3.5-15

5t=-18.5

divide both sides by 5;

t=-3.7

How do you determine whether you are finding a percent of increase or a percent of decrease between two values? Explain.

Slav-nsk [51]

Answer:

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

Step-by-step explanation:

Let's assume initial value as x

assume final value as y

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

For example:

Initial value is 40

So, x=40

Final value is 50

so, y=50

now, we can find percentage in increase

$=\frac{50-40}{40}\times 100$

$=25$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

For example:

Initial value is 50

So, x=50

Final value is 40

so, y=40

now, we can find percentage in decrease

$=\frac{50-40}{40}\times 100$

$=25$

PLS HELP ME

charle [14.2K]

Answer:

f(x) = 2x² +13x -7

Step-by-step explanation:

Given a root r, a factor of the expression with that root is (x -r). For your roots, the factors of a suitable polynomial are ...

(x -1/2)(x +7)

Since you don't want any fractions, you can multiply this by 2:

(2x -1)(x +7)

And you can eliminate parentheses and write it as a function.

f(x) = (2x)(x +7) -1(x +7) = 2x² +14x -x -7

f(x) = 2x² +13x -7

Help. The function f(x) = 3x-4/x+6 can be rewritten in the form f(x)= 3 + -22/x+6. What is the end behavior of y=f(x)

Andreyy89

The end behavior of $f(x) = \frac{3\cdot x - 4}{x + 6}$ is 3.

The end behavior of a rational function is the value of the <em>horizontal</em> asymptote to which the function tends when $x$ tends to $\pm \infty$ . We can determine the end behavior as following:

$f(x) = 3 - \frac{22}{x+6}$

When $x$ tends to $\pm \infty$ , then $\frac{22}{x+6} \to 0$ . Hence, we conclude that the end behavior of $f(x) = \frac{3\cdot x - 4}{x + 6}$ is 3.
