Write an equation of the line through (3,-5) and perpendicular to 3y=x-6
Alona [7]
3y = x - 6
y = 1/3x - 2. 
slope her is 1/3. A perpendicular line will have anegative reciprocal slope. To find the negative reciprocal of a number, u flip the number and change the sign. So the slope we need os -3/1 or just -3.(see how I flipped the slope and changed the sign)

y = mx + b
slope(m) = -3
(3,-5)...x = 3 and y = -5
now we sub and find b, the y int
-5 = -3(3) + b
-5 = -9 + b
-5 + 9 = b
4 = b

so ur perpendicular equation is : y = -3x + 4

HELPPPPP I NEED THIS
Andru [333]

Answer:

D. 1.3

Step-by-step explanation:

5(1.3) = 6.5

Since the value of r is .2 less than b, b would be 1.5

2(1.5) = 3

6.5+3=9.5

Segment AX and Segment EX are secant segments that intersect at point X. What is the length of ED? a. 1 b. 3 c. 6 d. 9
suter [353]

Answer:

B. 3

Step-by-step explanation:

We can use secant theorem.

AX × BX = EX × DX

AX = 7 + 2 = 9

9 × 2 = (3 + x) × 3

18 = 9 + 3x

18 - 9 = 3x

9 = 3x

x = 9/3 = 3

The length of ED is 3 units.

The value of a collectible coin can be represented by the equation y=2x+9.74, where x represents the number of years that Consue
enyata [817]
Y = 2x + 9.74
x = number of years owned
y = total value in dollars

y = 2(0) + 9.74
y = 9.74
Substitute x with 0 because the question asks what is the value of coin when consuelo originally purchased it. So, at the time of purchase it's been 0 years since he owned it.
