F(x) =- (3x +9) – 13 find f(-5)

belka [17]

$f(x) = -(3x + 9) - 13\\f(-5) = -(3 \cdot (-5) + 9) - 13\\= -(-15 + 9) - 13\\= -(-6) - 13\\= 6 - 13\\= - 7$

Answer:

k = -1

Step-by-step explanation:

Put the given value of x in the equation, and solve the resulting equation for k.

2(5 -3) +k(1 +2·5) = k - 5 - 1

2(2) +k(11) = k -6 . . . . simplify a bit

10k = -10 . . . . . . . . . . add -4-k to both sides

k = -1 . . . . . . . . . . . . . divide by 10

The value of k is -1.

_____

<em>Check</em>

Use k = -1 in the original equation and solve for x.

2(x -3) -(1 +2x) = -1 -x -1

2x -6 -1 -2x = -x -2 . . . . eliminate parentheses

x = 7 -2 = 5 . . . . . . add x+7; answer checks OK

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.

Zanzabum

Hi there!

The general formula of A line in slope-intercept form is the following:
$y = mx + n$

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
$y = \frac{2}{5} x + n$

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

$- 1 = \frac{2}{5} \times - 3 + n$

Multiply first.
$- 1 = - 1\frac{1}{5} + n$

And finally add 1 1/5 to both sides of the equation.
$\frac{1}{5} = n$

We can now switch sides.
$n = \frac{1}{5}$

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
$y = \frac{2}{5} x + \frac{1}{5}$
