Answer:
Step-by-step explanation:
Q.No.5
A) Domain is all the values that x can take. In the graph we see that domain is
the values of x from 0 to 12 hours
Domain is 0≤x≤12
B) Domain is the no of hours as per the graph i.e. lower limit 0 to 12 hours
A) Range is the values what y can take. Here the values temperature can take
From the graph we find that range is -2 to 4
-2≤y≤4
B) Range is the values what y can take. Here the values temperature can take
A) Decreases whenever y decreases as x increases. Here. decreases for
x=0 to x=2
B) Decreasing interval is (0,2) and this means whenever number of hours increases the temperature decreases.

You can use system of linear equations to find the solution.
The cost to customer to buy 5 tulips and 6 roses will be $17.75
Given that:
- The price of all tulips are same.
- The price of all roses are same.
- Price of 7 tulips and 9 roses is $25.90
- Price of 4 tulips and 8 roses is $19.80
To find:
Cost of buying 5 tulips and 6 roses.
Naming the prices:
- Let price of one tulip be $x
- Let price of one rose be $y
Forming system of equations:
By given data, we have:
7 tulip + 9 roses costs $25.90
or
And
4 tulips + 8 roses costs $19.8
or
Thus, we have two equations.
Using method of substitution:
From equation first, we have:
Substituting this value in second equation, we get:
Thus, we have:
Thus, the price of a tulip = x = $1.45
and the price of a rose = y = $1.75
Now, calculating price of 5 tulips and 6 roses:
Thus, the cost to a customer who buys 5 tulips and 6 roses would be $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.
Step-by-step explanation:
Let,
Cost of one tulip = x
Cost of one rose = y
According to given statement;
7x+9y=25.90 Eqn 1
4x+8y=19.80 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 7
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 20
Putting y=1.75 in Eqn 1
Dividing both sides by 7
Cost of 5 tulips and 6 roses = 5x+6y = 5(1.45)+6(1.75) = 7.25+10.50 = $17.75
It will cost a customer $17.75 to buy 5 tulips and 6 roses.

Answer:x=31
Step-by-step explanation:
the total degrees is 360 which can be cut into 2*(3x-5) + 2*(2x+30).
3x-5 +2x+30=180
5x+25=180
5x=155
x=31
to check your answer do 2*((3*31)-5) + 2*((2*31)+30) which equals 360
