5y- 2y because pemdas says go left to right when having the same symbol and they are compatible because they are the same 5y-2y is -3 and then minus 9x-0x this only gets rid of the x so now you have just 9 so were left with -3/9 I’m not sure what your slash is but here are the possible answers
If slash is addition it is 6
If slash is subtraction it is -12
If slash is multiplication it is -27
If slash is division it is -0.333
1 ft. = 12 in.
So that'd be 19 inches.
No, ur friend is not correct
| 3x + 8 | - 9 = -5....u have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides
| 3x + 8 } = -5 + 9
| 3x + 8 | = 4...so that number is not negative anymore
now u can set up ur 2 equations and solve for x...ur 2 equations would be:
3x + 8 = 4 and 3x + 8 = -4...so there will be 2 solutions
** if that -9 would not have been there, then ur friend would have been correct

Answer:
- A = (0, 1)
- B = (3, -2)
- area = 4.5 square units
Step-by-step explanation:
Rewriting the equations to make x the subject, we have ...
x = y² -1 . . . . . [eq1]
x = 1 - y . . . . . .[eq2]
At the points of intersection, the difference will be zero.
y² -1 -(1 -y) = 0
y² +y -2 = 0
(y -1)(y +2) = 0
The y-coordinates of points A and B are 1 and -2.
The corresponding x-coordinates are ...
x = 1 -{1, -2} = {1 -1, 1+2} = {0, 3}
Then A = (0, 1) and B = (3, -2).

A differential of area can be written ...
(x2 -x1)dy = ((1 -y) -(y² -1))dy = (2 -y -y²)dy
Integrating this over the interval y = [-2, 1] gives the area.
The area of the shaded region is 4.5 square units.
