For 222+203 it is best to start with 2+3=5
then 20+00=20
then add the two totals together 20+5=25
next 200+200=400
and last 400+25=425

What is 2xy-3yz+5+2yz-xy

melomori [17]

To simplify this expression, we are going to combine like terms.

First, we can see that we have two terms with the variables $xy$ being multiplied together, $2xy$ and $-xy$ . Together, these add to $xy$ , so our expression is now:

$xy - 3yz + 5 + 2yz$

We also have two terms with $yz$ , $-3yz$ and $2yz$ . Together, these add to $-yz$ , so our expression is now:

$xy - yz + 5$

Our final expression is xy - yz + 5.

A bicycle store costs $3300 per month to operate. The store pays an average of $75 per bike. The average selling price of each

Klio2033 [76]

S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even

Hope it helps!

Hey there!!

Fill in the blanks :-

⇒ First graph the line. Locate the value of x on the x-axis. Draw a vertical line from point plotted on the x-axis to the graph of the function and a horizontal line segment from the graph of the function to the y-axis.

Find the value of f(x) when x is -2.

$f(x) = \frac{3}{2}x-4$

Remember :- f(x) is basically the y-value. It is just denoted as _f(x), it stands for function of x. Which means, the value of y, depends upon the value of x or the function of x.

Given : x = - 2

Plugging in the values :

... $f(-2) = \frac{3*(-2)}{2}-4$

... $f(-2) = \frac{-3}{1} - 4$

... $f(-2) = -7$

The last fill in the blank :

The value of y on the y-axis is the value of the function. Therefore, the value of f(x) is -7 when x is -2.

Hope it helps!!

5. Solve using any method. y = -x + 8 y=x+4

vlada-n [284]

Answer:

Step-by-step explanation:

$\bold{ELIMINATION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8\\y=x+4&\TEXT{change the signs}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}y=-x+8\\-y=-x-4\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad0=-2x+4\qquad\text{add}\ 2x\ \text{to both sides}\\.\qquad2x=4\qquad\text{divide both sides by 2}\\.\qquad\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}$

$\bold{SUBSTITUTION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8&(1)\\y=x+4&(2)\end{array}\right\\\\\text{Substitute (1) to (2)}\\\\-x+8=x+4\qquad\text{subtract 8 from both sides}\\-x=x-4\qquad\text{subtract}\ x\ \text{from both sides}\\-x-x=-4\\-2x=-4\qquad\text{divide both sides by (-2)}\\\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}$
