Answer:
9x + 4
Step-by-step explanation:
Step 1: Write expression
4x - 2 + 5x + 6
Step 2: Combine like terms (x)
9x - 2 + 6
Step 3: Combine like terms (constants)
9x + 4
Answer:
w= -9
Step-by-step explanation:
28 + 19w= -8+15w
28 + 19w= -8+15w
-15w -15w
So then,
28 + 4w= -8
Next,
28 + 4w= -8
-28 -28
So then you'll have,
4w= -36
Then finally,
4w=-36
÷4w ÷4w
w= -9

Answer:
you just have to check the first and the third box
Step-by-step explanation:
put each into slop intercept form
y+6=-5(x-2) is the same as y=-5x+4
y-2=-5(x+6) is the same as y=-5x-28
y=-5x+4
y=-5x-28
all of them have a slope of -5, but you need to plug in (2,-6) to see which on is true
