x-\ original\ price\\\\
10x=45,50\ \ \ \ | divide\ by\ 10\\\\
x=4,550\$\\\\
Original\ price\ is\ 4,550\$.

The orginal problem was x times 10, so to find the original you'd have to do it backwards and divide by 10:

45.50/10 = 4.55$

Hope this helps!

X² - 8x - 33=0<br> complete the square
Andreas93 [3]
<h2>Answer:</h2><h2></h2><h2>\boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}</h2>

<h2>Explanation:</h2>

Step 1. Write x^2 - 8x - 33=0 in the form x^2+2ax+a^2=0

2a=-8\quad :\quad a=-4

Step 2. Add and subtract (-4)^2 to the left side of the equation

x^2-8x-33+\left(-4\right)^2-\left(-4\right)^2=0 \\ \\ \\ But: \\ \\  x^2+2ax+a^2=\left(x+a\right)^2 \\ \\ x^2-8x+\left(-4\right)^2=\left(x-4\right)^2

Step 3. Complete square

\left(x-4\right)^2-33-\left(-4\right)^2=0 \\ \\ \left(x-4\right)^2-49=0 \\ \\ (x-4)=\pm \sqrt{49} \\ \\ x-4=\pm 7 \\ \\ \boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}

Find the equation of a line parallel to y - 5x = 10 that passes through the point (3, 10). (answer in slope-intercept form)
s344n2d4d5 [400]
Y - 5x = 10 can be written in the slope-intercept form as
y = 5x + 10

The slope-intercept form is y = mx + b, where m = slope, and b = y-intercept.

In this case, the 5 is the slope.

Parallel lines have equal slopes, so the line we need to find also has a slope of 5. Its equation is

y = 5x + b

We need to find what b is.

We can use the given point, (3, 10), in for x and y and solve for b.

10 = 5 * 3 + b

10 = 15 + b

-5 = b

Now that we know that b = -5, we replace b with -5 to get our equation

y = 5x - 5
