So 1 head per squirel and 1 head per bird
4 legs per squirel and 2 legs per bird
s=number of squirels
b=birds
the equatinos should be
1b+1s=number of heads=16
and
2b+4s=number of legs=44
(note 2b=2 times b)
so we aolve
b+s=16 and 2b+4s=44
simplify the second equaiton by divideinb by 2
2b+4s=44
divide 2
b+2s=22
b+s=16
and
b+2s=22
we can actually add the two equations together with the first one made negative
-b-s=-16
<u>b+2s=22+</u>
0b+1s=6
s=6
subsitute
b+s=16
b+6=16
subtract 6 from both sides
b=10
10 birds
answer is c
It is growing at a rate of 9%.
The exponential equation is in the form
f(x) = a*(1+r)ˣ, where a is the initial value, r is the growth rate written as a decimal number, and x is the number of time periods. 1.09 is in the place of 1+r; this means r = 0.09 or 9%. Since we have a number greater than 1, it is increasing.
Answer:
The width is 15 feet.
The length is 17 feet.
Step-by-step explanation:Let length = 2x + 2
Let width = x
Let P = 94
P = 2L + 2W
94 = 2(2x + 2) + 2x
94 = 4x + 4 + 2x
94 = 6x + 4
94 - 4 = 6x
90 = 6x
90/6 = x
15 = x
When entering values of x in the function, it is observed that for k = 7 the results of f (x) displace 10 units. For this see the attached table. Therefore, for this case, the correct answer is k = 7 and the way to solve it is to substitute values of x in the given functions and see the results of f (x).I attach results.
