Answer:
2
Step-by-step explanation:
Y=mx+b
ok, so notice that b is constant, doesn't change, when x=0, then y=b
that is the starting value
it is stated that he has 41 at the begining so
y=mx+41
alright
so we are also given
when x=5, y=66
so find m
66=5m+41
miinus 41 from both sides
25=5m
divide both sides by 5
5=m
the equation is
y=5x+41

2 crossed straight lines, each with a measure of 180 degrees total
2 vertically opposite angles.
Problem
Prove x = 45
Proof
2x + 6 = 96 Vertical Angles are equal
2x + 6 - 6 = 96 - 6 Subracting equals from both sides of an equation does not destroy equality. When I learned this, we said e f e are e. "equals from equals are equal." It's a chant.
2x = 90 On the left it is the additive inverse is added to a number, the result is 0,
2x/2 = 90/2 Equality is not destroyed if both sides are divided by the same thing.
x = 45 QED
What the heck are you saying? I think you need you fix the question
