Answer: $\bold{y=\dfrac{1\pm \sqrt{4x+13}}{2}}$

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and solve for y:

$y+\dfrac{13}{4}=\bigg(x-\dfrac{1}{2}\bigg)^2\\\\\\x+\dfrac{13}{4}=\bigg(y-\dfrac{1}{2}\bigg)^2\rightarrow \text{(swapped the x's and y's)}\\\\\\\sqrt{x+\dfrac{13}{4}}=\sqrt{\bigg(y-\dfrac{1}{2}\bigg)^2}\rightarrow \text{(took square root of both sides)}\\\\\\\sqrt{\dfrac{4x+13}{4}}=\pm \bigg(y-\dfrac{1}{2}\bigg)}\rightarrow \text{(created common denominator in radical)}\\\\\\ \dfrac{\sqrt{4x+13}}{2}=\pm \bigg(y-\dfrac{1}{2}\bigg)}\rightarrow \text{(simplified radical)}$

$\pm \dfrac{\sqrt{4x+13}}{2}=y-\dfrac{1}{2}}\rightarrow \text{(divided both sides by}\ \pm )\\\\\\\dfrac{1}{2}\pm \dfrac{\sqrt{4x+13}}{2}=y\quad \rightarrow \text{(added}\ \dfrac{1}{2}\ \text{to both sides)}\\\\\\\dfrac{1\pm \sqrt{4x+13}}{2}=y\quad \rightarrow \text{(combined numerators)}$

Solve for x. Express the answer in simplest form,

slega [8]

$\frac{6x-1}{5}=\frac{3}{1} \ \ \ |\hbox{cross multiply} \\
6x-1=3 \times 5 \\
6x-1=15 \\
6x=15+1 \\
6x=16 \\
x=\frac{16}{6} \\
x=\frac{8}{3} \\
x=2\frac{2}{3}$

Determine the intercepts of the line. -7x - 6y = -15

Cerrena [4.2K]

Answer:

(0,5/2) y intercept

(15/7,0) x intercept

Step-by-step explanation:

To find the y intercept, let x = 0 and solve for y

0 - 6y = -15

Divide each side by -6

y = -15/-6

y = 5/2

(0,5/2)

To find the x intercept, let y = 0 and solve for x

-7x - 0 = -15

Divide each side by -7

-7x/-7 = -15/-7

x = 15/7

(15/7,0)
