Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
pls double check these im not super sure
im p sure the first one with || means parallel n second one means perpendicular lol
Answer:
m= ll m= -1/3
m= ⊥ m= 3
Step-by-step explanation:
uh regular slope
m = -1/3
parallel - slope is same
perpendicular - product of slopes is -1

3,4,7 just plug the x into the equation
Answer:
B
Step-by-step explanation:
We know that all of the ages are 7 apart so we don't need to mess with that.
Since Ed's age is 3/2 times Ted's age, we can make an equation.
Ted = t
Ed = e
e = 3/2t
Now we can just substitute and see if it checks out.
21 = 1.5 * 14
And since they are equal B is the answer.
