Answer:
-39
Step-by-step explanation:
||u|| = sqrt(5² + (-12)²)
= sqrt(25 + 144)
= sqrt(169)
= 13
||cu|| = c ||u||
c = -3
c ||u|| = -3 × 13 = -39
7/25, 9/10
For the denominators (25, 10) the least common multiple (LCM) is 50.
Therefore, the least common denominator (LCD) is 50.
14/50, 45/50
40 paper I think because 8 times 5 is 40
Subsitution is subsituting
y=3x-2
y=-x+6
subsitute 3x-2 for y in second equation
3x-2=-x+6
add x to both sides
4x-2=6
add 2 to both sides
4x=8
divide both sides by 4
x=2
subsitute
y=-x+6
y=-2+6
y=4
x=2
y=4
