Answer: 6 11/24
Step-by-step explanation:
33/8 + 2 1/3
= 33/8 + 7/3
= 155/24
= 6 11/24
Answer:
x= -1
Step-by-step explanation:
6-3x=5x-10x+4
6-3x=-5x+4
-4 -4
2-3x=-5x
+3x +3x
2=-2
2/-2=-2x/-2
-1=x
Answer:
the diagonal measurement from corner A to corner B=15 inches
Step-by-step explanation:
as we know that the loptop has the shape of a rectangle that means all it's angles are right angles. so we can use the pythogoras theorem to find out the diagonal of the rectangle.
let us denote the diagonal of rectangle by D and the sides of rectangle be denoted by X=12 and Y=9
so by using pythogoras theorem we have,
=225
D=15
Hence the diagonal measurement from corner A to corner B is 15 inches.
First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).
