Answer:
6 passengers got off at New Jersey
Step-by-step explanation:
let the number of passengers who got off be x and let the number of passengers who boarded the bus be y
y=2x
44 - x + y=50
y=50-44+x
y=6+x
subst y=2x
2x=6+x
2x-x=6
x=6
Make this into an equation keeping the number as x
3x-3 = 57+x
3x-x = 57+3
2x=60
x= 30
prove this by substituting the x
30*3 -3 =57+30
87=87
there you have it :)
Point slope form (slope intercept form) is y = mx + b
so first move the -x over to the other side
2y = x + 10
Divide 2 to both sides
2y/2 = y
(x + 10)/2 = x/2 + 5
slope intercept form
y = x/2 + 5
hope this helps
Answer:
f(7) = 1.08
Step-by-step explanation:
Given that:
f(5) = 12
A geometric sequence that is defined recursively by the formula
.....[1 ] where, n is an integer and n> 0.
Substitute n = 6 in [1] we have;
Using f(5) = 12 we have;
⇒
We have to find f(7).
Substitute n = 7 in [1] we have;
Substitute the given values f(6) = 3.6 we have;
Simplify:
f(7) = 1.08
Therefore, the value of f(7)to the nearest hundredth is, 1.08
Answer:
a=69
b=133
c=116
d=93
e=86
Step-by-step explanation:
<u>first start by finding angle a:</u>
angles in a triangle add up to 180 so we can simply do 180 - 40 - 71 = 69
<u>to find b:</u>
b is on a straight line so we can do 180 - 133 = 47
<u>to find d:</u>
d is part of the small triangle on the right of the diagram, we do not know one of the angles but because it is on a straight line we can do 180-140 = 40. Now to find d we can do 180 - 47 - 40 = 93
<u>to find e:</u>
i'm assuming the large triangle containing e is isosceles so we can do 180 - 2x47 = 86
therefore c is 116 as its the only answer left - hope this helps
