It should be -118.2 I just did that on an online calculator/solver. If its not the right answer I can try something different.
Answer:
4y-3x or -3x+4y
Step-by-step explanation:
first you have to distribute so you will do -1/3*9x and then -1/3*-12y
1. -1/3*9x=-3x
2. -1/3*-12y = 4y
then you have your answer 4y-3x or -3x+4y
Hope this helps!!!
Answer:
.7
Step-by-step explanation:
30/.7 is 21
Answer:
1) x+y=-2
x=-2-y
2) x-y=-8
substitude value of x
(-2-y)-y=-8
-2-2y=-8
-2y=-6
y=3
Substitute value of y in 1
x=-2-3
x=-5

If x is the age and y is the diameter of the trunk, write the equation:
ax+b=y
We must solve for a and b with the given information.
If (x, y) is (1, 4), we have:
a+b=4
If (x, y) is (10, 25), we have:
10a+b=25
Multiply the first equation by 10 to get:
10a+10b=40
Subtract the second equation from this to get:
9b=25
Thus b=25/9. a=4-25/9=11/9, so our equation is 11x/9+25/9=y.
