Answer:

x = 2

Step-by-step explanation:

Given

5x - 4 = - 3x + 12 ( add 3x to both sides )

8x - 4 = 12 ( add 4 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Complete the equation of the line through (2,-2) and (4,1).
scoundrel [369]
Slope formula : (y2 - y1) / (x2 - x1)
(2,-2)....x1 = 2 and y1 = -2
(4,1)...x2 = 4 and y2 = 1
now we sub into the slope formula and solve for the slope
slope = (1 - (-2) / (4 - 2) = (1 + 2) / 2 = 3/2

now we use y = mx + b
slope(m) = 3/2
use either of ur points....(4,1)...x = 4 and y = 1
now sub into y = mx + b formula and find b, the y int
1 = 3/2(4) + b
1 = 6 + b
1 - 6 = b
-5 = b

so ur equation is : y = 3/2x - 5 <==

\huge\text{Hey there!}

\mathsf{v + 25 < 5}

\large\textsf{SUBTRACT 25 to BOTH SIDES}

\mathsf{v + 25 - 25 < 5 - 25}

\large\textsf{CANCEL out: 25 - 25 because that gives 0}

\large\textsf{KEEP: 5 - 25 because it gives us v or solve for it}

\mathsf{v < 5 - 25}

\mathsf{5 - 25 = -20}

\boxed{\boxed{\large\textsf{Answer: }\mathsf{\bf v < -20}}}\large\checkmark\\\boxed{\boxed{\mathsf{\bf It\ is\ an\ O P E N E D\ circle\ on\ -20\ shaded\ to\ the\ left}}}
