Answer:I think the pair that is perpendicular is
Y=2/3x
Answer:
252
Step-by-step explanation:
7/25=252/900
Answer:
11/381
Step-by-step explanation:
Not sure what the ? after each number means but I'm going to assume they aren't there
so we need find the number of tokens in all which is
44+1414+66=1524
P(red)=44/1524 now reduce giving P(red)=11/381
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
Answer:
<h3>x = 2</h3>
Step-by-step explanation:
3x + 5 = 19 - 4x <em>subtract 5 from both sides</em>
3x = 14 - 4x <em>add 4x to both sides</em>
7x = 14 <em>divide both sides by 7</em>
x = 2
