Answer:
y= -x+6
Step-by-step explanation:
The equation was in point slope from, so you had to solve for y using inverse operations. The slope of x is -1 because -x = -1x.
Answer:
C
Step-by-step explanation:
4 X 4 X 4 X 4 X 4 and 4⁵
we can write 4 X 4 X 4 X 4 X 4 like 4⁵
4 X 4 X 4 X 4 X 4 = 4⁵
Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.
Answer:
-6y = 70x = 3
Step-by-step explanation:
-6x - 5y= 64x+ y=3
---------------------------
-y - y
---------------------------------
-6x -6y = 64x = 3
------------------------------------
+6x +6x
-------------------------------------
-6y = 70x = 3
Answer:
Each hat is $5
Each mask is $3
Step-by-step explanation:
Hat= x dollars
Mask= y dollars
Now,
3 hats and 4 mask sold = $27
We can write
3x + 4y = 27
Adding the second equation (-1 times 1st equation) gives us;
3x + 6y = 33
-1* (3x + 4y = 27)
3x + 6y = 33
-3x -4y = 27
2y = 6
y = 6/2
***y = 3***
Now we replace y= 3 into 1st equation and solve for x:
3x + 4y = 27
3x + 4(3) = 27
3x + 12 = 27
3x + 15
x = 15/3
***x= 5***
Each hat costs $5
Each mask costs $3
