Step-by-step explanation: divided 81 and 3. the answer is 27. multiply 27 x 4 you get 108.
Answer:
$106.95
Step-by-step explanation:
45% = 0.45
1.00 - 0.45 = 0.55
$69 x 0.55 = 37.95
$69 + 37.95 = $106.95
Answer:
<u>The equation is x = y * 4/5 and US$ 12 would equal 15 Swiss Francs</u>
Step-by-step explanation:
<u>1. Let's review all the information provided for solving this question:</u>
1 US$ equivalent to 1 1/4 Swiss Franc
2. Let's write and solve a multiplication equation to find the amount of US$ that would equal 15 Swiss Francs
x = Amount of US$ equivalent
y = Amount of Swiss Francs
x = y /1.25
x = y / 5/4 (1.25 = 5/4)
<u>x = y * 4/5</u>
Now, let's replace with the real values:
x = 15 * 4/5
x = 60/5
<u>x = 12</u>
<u>US$ 12 would equal 15 Swiss Francs</u>
(a)
Domain:
we know that domain is all possible values of x for which any function ios defined
Here, curve is defined for all values of x
so, domain is
Range:
Range is all possible values of y for which x is defined
minimum value of y is -4
maximium value of y is +inf
so, range is
(b)
x-intercept:
It is the value of x where f(x)=0
so, the point where curve intersects on x-axis
and we get
and
(c)
Increasing interval:
where curve is moving upward
we can see that
Decreasing interval:
where curve is moving downward
we get
Constant:
constant means horizontal line
there is no horizontal line here
so, it does not exist
(D)
End behavior:
when x-->+inf
y is moving upward
so, y---->+inf
when x-->-inf
y is moving upward
so, y---->+inf
(E)
we can see that curve jupms at x=-1
so, there is discontinuity at x=-1
and this is jump type of discontinuity
(F)
For odd:
f(-x)=-f(x)
For even:
f(-x)=f(x)
we can see that none of them holds true
so, this is neither
