Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.
Answer:
2
Step-by-step explanation:
If by gradient you mean slope....parallel lines have the same slope
rearrange equation to get in y = mx + b format
-2x + y - 5 = 0
y = 2x + 5
Slope is 2
Step-by-step explanation:
for a mid point of (-3,-5) and(5,3) is.
(X1,Y1)= (-3,-5)
(X2,Y2)=(5,3)
now,
midpoint=(x1+x2)/2, ,(y1+y2)/2
=(-3+5)/2, (-5+3)/2
=2/2, (-2)/2
=( 1, -1)
:- midpoint=(1,-1)
Answer:
15
hope this helps
have a good day :)
Step-by-step explanation:
9/15 and 2/15 just
the mutiples of 5=5, 10, 15, 20
the multiples of 15=15, 30, 45, 60
so the common denominator is 15 so multiple 5 and 3 to get the denominator is 15 and the numerator of 9
