9 Ounces shows the total amout because you need to subtract 21-17

For each ordered pair (x,y) determine whether it is a solution to the inequality 7x+2y>_26

MA_775_DIABLO [31]

The inequality is given as,

$7x+2y>-26$

Consider that any ordered pair (x,y) is said to be the solution of the inequality if the ordered pair gives a true result when substituted in the inequality.

Consider the ordered pair (4,-9),

$\begin{gathered} 7(4)+2(-9)>-26 \\ 28-18>-26 \\ 10>-26 \end{gathered}$

Clearly, the result is true. So it can be concluded that (4,-9) is a solution of the given inequality.

Therefore, mark YES for the ordered pair (4,-9).

Consider the ordered pair (3,4),

$\begin{gathered} 7(3)+2(4)>-26 \\ 21+8>-26 \\ 29>-26 \end{gathered}$

Clearly, the result is true. So it can be concluded that (3,4) is a solution of the given inequality.

Therefore, mark YES for the ordered pair (3,4).

Consider the ordered pair (-4,0),

$\begin{gathered} 7(-4)+2(0)>-26 \\ -28+0>-26 \\ -28>-26 \end{gathered}$

Clearly, the result is false as -28 is not actually greater than -26.

So it can be concluded that the ordered pair (-4,0) is not a solution of the given inequality.

Therefore, mark NO for the ordered pair (-4,0).

Consider the last ordered pair (-6,8),

$\begin{gathered} 7(-6)+2(8)>-26 \\ -42+16>-26 \\ -26>-26 \end{gathered}$

Note that the numbers on both sides of the inequality are identical. So there should be the symbol of equality, not inequality. So, it can be concluded that this ordered pair (-6,8) is not a solution of the given inequality.

Therefore, mark NO for the ordered pair (-6,8).

What is the value of the expression?<br> |-2- (-2.5)<br> -4.5<br> –0.5<br> 0.5<br> 4.5

Snezhnost [94]

Answer: -0.5

Step-by-step explanation: Lets solve the equation, don't forget that your answer is an absolute value.

|-2-(-2.5)|

|0.5| Absolute value of 0.5 is -0.5

So, the answer is -0.5

This table shows values that represent an exponential function.

mr_godi [17]

Answer:

3

Step-by-step explanation:

When you go from x=1 to x=3 you go up twice on the x-value. The y value also increases by 6 which means all you have to do is find the average.

6/2= 3

3 is the average increase between x=1 and x=3

Hope this helps!

A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 10 inches, a

tankabanditka [31]

Answer:

Surface area means all of the outside areas, kind of like when you wrap a present.

Step-by-step explanation:

1st draw the box and find the area of the top and the bottom of the figure

10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.

2nd find the area of two opposite sides:

10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both

3rd find the area of the last two opposite sides:

3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.

4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
