Answer: (-1,0)
------------------------------------------------
Explanation:
A quick method is to simply look at the graph and notice the two altitudes cross at (-1,0)
----------
A longer method involves a bit of algebra but its not too bad
y = x+1
y = -1+1 ... plug in x = -1 (ie replace x with -1)
y = 0
So when x = -1, the value of y is y = 0
They pair up to get (x,y) = (-1,0) which confirms what the graph is showing

idk the bottom one
Step-by-step explanation:
A: -vp + 30 < 45
Subtract 30 from both sides.
-vp < 15
Divide both sides by -v.
p > -15/v
( when dividing a negative, the < sign must be changed to >)
B. 3w - 6r = 30
Subtract 3w from both sides.
-6r = -3w + 30
Divide both sides by -6
r = (-3w + 30)/ -6
simplify the right side
r = (w - 10)/2
OR
r = (-3w/-6) + (30/-6)
r = w/2 - 5
