Answer:
2y + 2x = 0
Step-by-step explanation:
First you have to find the slope of the line.
Parallel lines have same slope
2y = -2-2x
y=-1-1x, y=-1x-1
slope = -1
Use point slope formula
y-y=m(x-x)
y-(-9) = -1(x-9)
y+9 = -1(x-9)
y+9 = -1x+9
y = -x
y + x = 0
2y + 2x = 0
Answer:
83.74 in squared
Step-by-step explanation:
The area of the original rectangle is: 14 * 8 = 112 in squared.
The area of a circle is 
, where r is the radius. In this case, we know the diameter is 6, so the radius is 3. Then, the area of the circle is:
3.14 * 3^2 = 3.14 * 9 = 28.26 in squared.
The remaining area is just the total minus the circle area:
112 - 28.26 = 83.74 in squared
If you are converting, make the denomenator 100 for fractions or look at 2 decimal places for decimals. if you want to find a certain percentage for a total, make the total of the item 100% and from there find 1% and multiply to the wanted percentage
Answer:
117 units
Step-by-step explanation:
if you use the ratio of the two longest sides then you can find all side lengths
= 
; x = half of 52, or 26
= 
; 20x = 52 · 15
20x = 780
x = 39
add to get perimeter: 52 + 26 + 39 = 117 units
Answer:
C
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 39) which sum to give the coefficient of the x- term (- 10)
The factors are - 13 and + 3, since
- 13 × 3 = - 39 and - 13 + 3 = - 10, hence
x² - 10x - 39 = (x - 13)(x + 3) ← in factored form
x - 13 is a factor → C
