Answer:
Last one: ⅗
Step-by-step explanation:
cosF = adjacent/hypotenuse
cosF = FD/FE
= 6/10
= 3/5
Answer:
y = -41
Step-by-step explanation:
y= -7x -6
y= -7(5) -6
y= -35 -6
y= -41
X² - 4x + y² - 8y = 5
Complete the square:
x² - 4x + (4) + y² - 8y + (16) = 5 + (4) + (16)
→ (x - 2)² + (y - 4)² = 25
Center: (2,4)
radius: √25 = 5
Answer:
y =6x+17
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-7- -1)/(-4 - -3)
= (-7+1)/(-4+3)
-6/-1
6
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 6x+b
Substitute a point into the equation
-1 = 6(-3) +b
-1 = -18+b
Add 18 to each side
17 =b
The equation is
y =6x+17
179 / 9 is about 20
exact = 19.888888
