<h2>20cm</h2><h2>-------------------------------</h2>
<u>Step-by-step explanation:</u>
sides are 4cm, 8cm, 8cm ----( because isosceles triangle have 2 sides equal )
so, perimeter = sum of all sides
= 4 + 8 + 8
<h3> = 20cm</h3><h2>-------------------------------------</h2><h2>FOLLOW ME</h2>
Answer:
I'm not sure what your question is but let me give you a little math lesson. when you have a y intercept, the number given is your y coordinate, that is at what point on the y axis your line is crossing. so on this line we have the point (0,12) we know this because the line crosses on the y axis so therefore our x value has to be zero.
Because they have given us the slope you simply start at an already known coordinate. (0,12) and use the old rise over run rule. because the slope is negative you know your line is going to look like this \ so start at 12 and go down four. (0,8) then to the right one. (1,8) and that would be another point on your line.
Sllope intercept form is y=mx+b
m is the slope , b is the y itnercept
so early pay
cost=70 flat rate
x=infinity
the equation would be y=70
deposit pluss
you have to pay an initial one time payment of 15 so
y=mx+15
then 4 dollars per day
4 times number of days
y=4x+15
daily pay is 6 dollars per day so 6 times number of days
y=6x
1.
a. y=70
b. y=4x+15
c. y=4x
2(17)+7
34+7
N(17)=41
