<h3>Answer: A) 2</h3>
=====================================================
Work Shown:
u(50654) = 5+0+6+5+4 = 20
u(20) = 2+0 = 2
u(50654) = 2
We want to find all possible values of m such that u(m) = 2 and also m is some two-digit integer.
-----
Possible values of m are: m = 11, m = 20
u(m) = u(11) = 1+1 = 2
u(m) = u(20) = 2+0 = 2
and that's it. There are no other ways to have two positive integers add up to 2.
Answer:
x=−1 and y=3 or (-1,3)
WORK:
Let's solve your system by substitution.
y=2x+5;y=−3x
Step: Solve y=2x+5 for y:
y=2x+5
Step: Substitute 2x+5 for y in y=−3x:
y=−3x
2x+5=−3x
2x+5+3x=−3x+3x (Add 3x to both sides)
5x+5=0
5x+5+−5=0+−5(Add -5 to both sides)
5x ÷ 5 = -5÷5 (divide both sides with 5)
x=−1
Step: Substitute −1 for x in y=2x+5:
y=2x+5
y=(2)(−1)+5
y=3(Simplify both sides of the equation)
Answer:
x=−1 and y=3
(Incase you needed to show your work)
