Answer:

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Step-by-step explanation:
We can find the slope through two points.
m = (y2 - y1)/(x2 - x1)
m = (4 - -5)/(4 - -8)
m = 9/12 = 3/4
The slope of the line is 3/4.
Slope-intercept form of a line is y=mx+b. Where m is the slope and b is the y-intercept.
y = 3/4x + b
A point on the line is (4, 4). x = 4 and y =4.
4 = 3/4(4) + b
4 = 3 + b
b = 1
The y-intercept is 1.

Answer:
all work is shown and pictured
For this case, we must indicate the fraction that is equivalent to 0.53.
It is observed that the decimal is rolled twice to the left, that tells us to divide by 100.
Thus, dividing the whole number "53" among 100 we have:

Step-by-step explanation:
<u>Step 1: Define</u>
2x² - 20x = x² - 19
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract x² on both sides: x² - 20x = -19
- Complete the Square [Addition Property of Equality]: x² - 20x + 100 = -19 + 100
- [Complete the Square] Simplify: (x - 10)² = 81
- [Equality Property] Square root both sides: x - 10 = ±9
- [Addition Property of Equality] Add 10 on both sides: x = 10 ± 9
- Evaluate: x = -1, 19
