Write an equation of the line through each point. Use slope-intercept form (1,-1); parallel to y=2/5x-3

1 answer:

6 0

Y = 2/5x - 3....the slope here is 2/5. A parallel line will have the same slope.

y = mx + b
slope(m) = 2/5
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = 2/5(1) + b
-1 = 2/5 + b
-1 - 2/5 = b
-5/5 - 2/5 = b
-7/5 = b

so ur parallel equation is : y = 2/5x - 7/5

Answer:

B) 1 < x < 13

Step-by-step explanation:

use triangle inequality theorem which states that the sum of any two sides must be greater than the third side

let x = third side

6 + 7 > x; x < 13

6 + x > 7; x > 1

x + 7 > 6; x > -1

there will always be one inequality which produces a negative value which you can exclude from your answer because a length cannot be negative

What is the solution to the system of equations? X+y=6

V125BC [204]

X = y + 2
( y + 2 ) + y = 6 -> 2y + 2 = 6
2y = 6-2
y = 2

X + 2 = 6
-> x = 4
