Answer:

Step-by-step explanation:

Simplifying

d + -5 = 7

Reorder the terms:

-5 + d = 7

Solving

-5 + d = 7

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + d = 7 + 5

Combine like terms: -5 + 5 = 0

0 + d = 7 + 5

d = 7 + 5

Combine like terms: 7 + 5 = 12

d = 12

Simplifying

d = 12

What is the standard form equation of the line shown below?
jolli1 [7]
(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b

so ur equation is : y = -1/3x + 14/3....however, this is not ur answer because it is not in standard form.

y = -1/3x + 14/3
1/3x + y = 14/3....multiply both sides by 3
x + 3y = 14 <=== standard form
