21.
an=a1+d(n-1)
a1=first term
an=nth term
d=common differnce
n=which term

firs term is 1
common differnce is 4 (1+4=5)
so

an=1+4(n-1)
or
an=1+4n-4
an=-3+4n


22.

solve for n such that
-3+4n=95
add 3 to both sides
4n=98
divide both sides by 4
n=24.5
we can't have a non-whole number for n because it names a number, we can't have the 24.5th number, we can have the 24th or 25th, but not the 24.5th

What is the equation of a line that passes through (-4, 3) and (6, -2) ?
s2008m [1.1K]
First find the slope
the slope of the line that passes through (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

given
(-4,3) and (6,-2)
the slope is (-2-3)/(6-(-4))=(-5)/(6+4)=-5/10=-1/2

so
the equation of a line tat passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
use (-4,3)
and we found slope=-1/2
y-3=-1/2(x-(-4))
y-3=-1/2(x+4)
if yo want slope intercept form
y-3=-1/2x-2
y=-1/2x+1
if yo want standard form
1/2x+y=1
x+2y=2

Please help I need help with this question

Answer:

2.5% and 2.5 · 10^-3, 0.25, 2/5, √5

Step-by-step explanation:

0.25, 2/5, 2.5 · 10^-3, 2.5%, √5

Now let's list them all in the same form, why not decimals.

0.25 = 0.25

2/5 = 4/10 = 40/100 = 0.4

2.5 · 10^-3 = 2.5 · 0.01 = 0.025

2.5% = 0.025

√5 ≅ 2.236
