Pls i seriously don’t get anything

(1)

distribute parenthesis on both sides of the equation and simplify

10r - 30 = 4r + 52 - 10r - 50

10r - 30 = - 6r + 2 ( add 6r to both sides )

16r - 30 = 2 ( add 30 to both sides )

16r = 32 ( divide both sides by 16 )

r = 2

(2)

distribute parenthesis

- 0.5x + 5 < 12 ( subtract 5 from both sides )

- 0.5x < 7

divide both sides by - 0.5, remembering to reverse the inequality symbol as a consequence

x > - 14 → (C)

(3)

obtain the equation of the line in slope-intercept form

y = mx + c ( m is the slope and c the y-intercept )

calculate the slope using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 3 ) ← 2 points on the line

m = = -

the y-intercept = (0, 2 ) ⇒ c = 2

y = - + 2 ← equation of line

the shaded area ( the solution ) is below the line which is solid, thus

y ≤ - x + 2 → (B)

(4)

This data can only be a function if each value of x maps to exactly one value of y

The only values satisfying this criteria are B, C and D

as 0 → 1 and - 3 → - 1 so cannot map to other values of y

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
