Answer:

1.1h+0.75c=4.55---------------1

h+c=5--------------2

Step-by-step explanation:

Step one:

given data

total lunch items= 5

let hot dogs be h

and cookies be c

cost of hot dogs = $1.10

cost of cookies = $0.75

total cost = $4.55

Step two:

The linear model for the total cost is given as

4.55=1.1h+0.75c---------------1

and the model for the number of items is

h+c=5--------------2

The systems of the equation for the situation is

1.1h+0.75c=4.55---------------1

h+c=5--------------2

5/2.35 = x/12<br> what does x=
postnew [5]

Answer:

x = \frac{60}{2.35} or x = 25.531...

Step-by-step explanation:

<u>Step 1:  Cross Multiply</u>

<u />\frac{5}{2.35} = \frac{x}{12}

5(12) = 2.35(x)

60 = 2.35x

<u>Step 2:  Divide both sides by 2.35</u>

<u />60 / 2.35 = 2.35x / 2.35

x = \frac{60}{2.35} or x = 25.531...

Answer:  x = \frac{60}{2.35} or x = 25.531...

1. To solve this exercise, you must apply the formula for calculate the area of a trapezoid, which is shown below:
<span> 
 A=(b1+b2/2)h
</span><span> 
 A is the area of the trapezoid.
</span><span> b1 is the larger base of the trapezoid (b1=16-4=12 ft).
</span><span> b2 is the smaller base of the trapezoid (b2=10-4=6 ft).
</span><span> h is the height of the trapezoid (h=12-4=8 ft)
</span><span> 
 2. When you substitute these values into the formula A=(b1+b2/2)h, you obtain:
</span><span> 
 A=(b1+b2/2)h
</span><span> A=(12 ft+6 ft/2)(8 ft)
</span><span> A=9 ftx8ft
</span><span> A=72 ft² 
</span><span> 
 3. </span><span>The length of fencing is:</span>  a²=b²+c² a=√b²+c² a=√(8 ft)²+(6 ft)² a=10 ft  Perimeter (Length of fencing)=12 ft+8 ft+6 ft+10 ft=36 ft

Which equation represents the graphed function
xxMikexx [17]
It’s easy just find the slope and the answer is gonna be obvious

Slope= y2-y1/x2-x1

Slope = -2-(-1)/0-4 = -1/-4 = 1/4

Slope = 1/4x

So the answer should be C

the graph F(x) shown below resembles the graph of g(x) = |x| but it has been flipped over the x axis which of the following is t
Radda [10]

Answer:

f(x)=-|x|

Step-by-step explanation:

We have been given a graph of f(x) which resembles with the graph of function g(x) where g(x)=|x|.

It says that graph is flipped over the x-axis.

Now we have to find about which of the following choice correctly describes the given graph.


We know that |x| means absolute value of x so that means g(x)=|x| is absolute function in shape of V.

We know that flipping over x-axis can be done by changing f(x) into -f(x).

<u>Hence correct answer is choice D) F(x)=-|x|</u>
