Solve for X: 1/2(4+X)+2=16
Zanzabum
1/2(4+X)+2=16
2+(0.5 x X) + 2 = 16

Solve the system of linear equations by substitution.<br><br>−2x−5y=3<br> 3x+8y=−6
Sliva [168]
First you want to know what y or x is i chose y for this on 

so the equation i'm going to use is -2x-5y=3
i want to solve for y

-2x-5y=3
+2x        +2x

-5y=2x+3
 /-5   /-5  /-5
y=-2/5x+-3/5

Now that i solved for y we substitute our answer into the next equation to solve for x like this:

3x+8y=-6
3x+8(-2/5x+-3/5)=-6
3x+ -3.2x+-4.8=-6
-0.2x+-4.8=-6
          +4.8  +4.8
-0.2x=-1.2
/-0.2    /-0.2
x=6

After you know what x is you substitute it in for any of the equations that we started with. I picked 3x+8y=-6 to find y.

3x+8y=-6
3*6+8y=-6
18+8y=-6
-18      -18
8y=-24
/8     /8
y=-3

Since we know what x and y are we substitute it with any of the equations that we started with. i picked -2x-5y=3

-2*6-5*-3=3
-12- -15=3
3=3 
so our solution (6,-3) works

Explain what the slope and intercept mean in the situation.
Vera_Pavlovna [14]

Answer:  The slope is the cost per muffin and the intercept of 3 is the delivery charge.

Step-by-step explanation:

I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis.  A slope of 2 means that y will increase by 2 for every 1 increase in x.  That means that the price of a single muffin is $2.

The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3.  One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.

10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.
