Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 2y = 7 into this form

Subtract 3x from both sides

2y = - 3x + 7 ( divide all terms by 2 )

y = - $\frac{3}{2}$ x + $\frac{7}{2}$ ← in slope- intercept form

with y- intercept c = $\frac{7}{2}$ → C

1. Find the value of x.<br> 2. Find the value of y.

DiKsa [7]

Answer:

$5y + 85 = 180 \\ 5y = 10 - 85 \\ 95 \div 5 = 19 \\ 5x + 95 = 180 \\ 5x = 180 - 95 \\ 5x = 85 \\ x = 17$

Find a formula for the inverse of the function. f(x) = e^6x − 9

STatiana [176]

Answer:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

Step-by-step explanation:

So we have the function:

$f(x)=e^{6x}-9$

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

$x=e^{6f^{-1}(x)}-9$

Add 9 to both sides:

$x+9=e^{6f^{-1}(x)}$

Take the natural log of both sides:

$\ln(x+9)=\ln(e^{6f^{-1}(x)})$

The right side cancels:

$\ln(x+9)=6f^{-1}(x)$

Divide both sides by 6:

$f^{-1}(x)=\frac{1}{6}\ln(x+9)$

And we're done!
