3x - 50 = -20
Add 50 to both sides
3x = 30
x = 10
The number is 10
Your answer for the first inequality is D) s less than or equal to -2
2nd inequality: I got the answer s<55/8.
Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 4 ) and (x₂, y₂ ) = (2, 2 )
m = = = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 2 ) , then
2 = - 4 + c ⇒ c = 2 + 4 = 6
y = - 2x + 6 ← equation of line
19 is the answer 4+5(3)= 4+15=19
If you’re trying to elimination the answer would be (14,9)
