Hello :
answer : <span>B. u=2, v=0 becausse :
5(0)-(2) = -2....right
-(2/+9(2) = 18...right</span>
A) The side length is 5 units since 5*5*5 = 125. You can guess and check to see which value multiplies with itself three times to get 125. Or you can take the cube root of 125 to get 5. You can type in 125^(1/3) to indicate you want the cube root of 125
b) The volume is 64 cubic units. Multiply the side length 4 by itself three times: 4*4*4 = 64.
Answer:
x=3, y=4. (3, 4).
Step-by-step explanation:
y=-x+7
y=x+1
-----------
-x+7=x+1
-x-x+7=1
-2x=1-7
-2x=-6
2x=6
x=6/2
x=3
y=3+1=4
If two lines intersect, then there are two possibilities
A) The lines intersect at exactly one point. This happens if the slopes of the two lines are different (the y intercepts may or may not be the same).
B) The lines intersect at infinitely many points. This happens when both slopes are the same and when both y intercepts are the same. In short, the two equations are identical. Often they may be written in different forms. For example, the equation y = 2x+1 and 2y = 4x+2 are the same equation. Divide everything in equation (2) by 2 and you'll get equation (1).
