Alright Fabian, here's the deal.

First you need to solve the inequality for k. To do this, you have to
a) distribute the -(3k + 4)
b) collect like terms: -k - 3k
c) move the term with k to the left (optional but it's a habit)
d) divide both sides by the coefficient. Check out picture for details.

Liono4ka [1.6K]

Answer:

$\huge \frac{8}{45}$

Step-by-step explanation:

$\frac{9}{10} - \frac{13}{18} \\ \\ = \frac{9 \times 9}{10 \times 9} - \frac{13 \times 5}{18 \times 5} \\ \\ = \frac{81}{90} - \frac{65}{90} \\ \\ = \frac{81 - 65}{90}\\ \\ = \frac{16}{90} \\ \\ = \frac{8}{45} \\$

The given equation is:

y = -10x + 1
Slope of this equation = -10

New line will be perpendicular to this line, so slope of new line = 1/10

So, we are to find the equation of a line with slope 1/10 and passing through (5,7). Using the point slope form we can write

y - 7 = 1/10 ( x - 5)
y = x/10 -1/2 + 7
y = x/10 + 13/2
⇒
x/10 - y = -13/2

So option C gives the correct equation of the new line
