Answer:
- Perimeter of the original Rectangle is
2(4.5+4.3)=2×8.8= <u>17.6</u><u> </u><u>mm</u>
- Side length of the enlarged rectangle is

- Perimeter of the enlarged rectangle
2(24.3+23.22)= 2×47.52= <u>95.04 mm</u>
Answer:
b) 690 - 7.5*t
c) 0 < t < 92s time (t) is independent quantity
d) 0 < s < 690ft distance from bus stop (s) is dependent quantity
e) f(0) = 690 ft away from bus stop , f(60.25) = 238.125 ft away from bus stop
Step-by-step explanation:
Part a - see diagram
part b
initial distance from bus stop s0 = 690 ft
distance covered = 7.5*t
s = s0 - distance covered
s = 690 - 7.5*t = f(t)
part c
s = 0 or s = 690
0 = 690 -7.5*t
t = 92 s
Hence domain : 0 < t < 92s time (t) is independent quantity
part d
s = 0 or s = 690
Hence range : 0 < s < 690ft distance from bus stop (s) is dependent quantity because it depends on time (t)
part e
f(0) is s @t = 0
f(0) = 690 ft away from bus stop
f(60.25) is s @t = 60.25
f(60.25) = 690 - 7.5*60.25 = 238.125 ft away from bus stop.
5*3 + 5*4
The 5 must multiply through the parenthesis.
Answer:
x=2 y=-2
Step-by-step explanation:
you can solve this with the elimination process
-10x+6y=-32
-6x+6y=-24
you can multiply the bottom equation by a -1
-10x+6y=-32
-1(-6x+6y=-24)
making it
-10x+6y=-32
6x-6y=24
this allows you to cancel out 6y because 6y-6y=0
so you are left with
-10x=-32
6x=24
add them
-10x=-32
+6x=24
________
-4x=-8
divide by -4=2
x=2
plug that into the original equation
-10(2)+6y=-32
-6(2)+6y=-24
=
-20+6y=-32
-12+6y=-24
add them
-20+6y=-32
+-12+6y=-24
_________
-32+6y=-56
add 32
-56+32=-24
y=-24
