Answer:
(x, y) = (4, 9)
Step-by-step explanation:
Perhaps the ordered pair you want is the one that satisfies both equations.
We can find that by equating the expressions for y:
x +5 = 3x -3
8 = 2x . . . . . . . . add 3-x to both sides
4 = x . . . . . . . . . divide by 2
y = 4+5 = 9
The ordered pair is (x, y) = (4, 9).
Answer:
B
Step-by-step explanation:
given the first 3 terms of the geometric sequence - 4, 20, - 100
with r =
=
= - 5
the n th term formula ( explicit formula ) is
=

here r = - 5 and
= - 4, hence
= - 4
with n ≥ 1
Answer:
f(x) = (-4/5)*x + 4
Step-by-step explanation:
The line which passes through these points will decrease y by 12 for every x increase of 15. This is the same as decreasing y by 4 for every x increase of 5. This means the slope (rise over run) is -4/5. If this is applied to the first point to find what y is at 0, then the point (0, 4) is on the line.
This means that f(x) = (-4/5)*x + 4
Answer: 0. 625 hour
Step-by-step explanation:
Given;
distance = 2 1/2 mile= 5/2 mile
speed = 4mile/hr
speed = distance /time
time = distance/speed
=5/2 / 4
= 5/2 × 1/4
=5/8
=0. 625 hour
we can convert to minute by simply multiplying by 60
Time taken (in minute) = 0. 625 × 60 = 38minutes
Answer:
603000
Step-by-step explanation:
f(t(w))=25000+40(14200+250)
f(t(w))=25000+40(14450)
f(t(w))=25000+578000
f(t(w))=603000
