Answer:

-6

Step-by-step explanation:

7x + 2 = 5(x - 2) \\ 7x + 2 = 5x - 10 \\ 7x - 5x =  - 10 - 2 \\ 2x =  - 12 \\ x =  \frac{ - 12}{2}  \\ x =  - 6

HELPPP ME PLEASEE!!!! ONLY NUMBER 7 ON HOW TO GRAPH AND NUMBER 9 PLEASEEE. I REALLY NEED THIS I START SCHOOL TOMORROW
lana66690 [7]

Answer:

7.) write 0 in one of the dashes and then you can count with fractions or decimals.

Draw an open circle (not filled in) on the 17/3 dash. Then draw the arrow going the same direction as #8.

9.)

64 \leqslant 24 +  x

He still needs 40 oz to drink.

40 (<em>less</em><em> </em><em>than</em><em> </em>or equal to sign) x

Step-by-step explanation:

*Find how many ounces in 8 cups

8 cups × 8 ounces = 64 ounces

**Figure out the sign

- it has to be equal to because his goal is to drink <em>at</em><em> </em><em>least</em><em> </em>64 oz.

- the sign has to also be greater than because he want to drink more than 64 if possible for him

***What goes on the other side of the sign?

- the 24 oz that he already drank plus the needed amount, let it be <em>x</em><em> </em>for unknown

<em>-</em><em> </em>the equation is 24 + unknown, or 24 + <em>x</em>

****Join all parts to get equation:

64 \leqslant 24 + x

*****isolate <em>x</em>

<em>-</em><em> </em>subtract 24 to both sides to cancel out the 24 on the side with <em>x</em>

******Answer to how many oz he still needs:

40 (less than or equal to sign) <em>x</em>

<em>Oops</em><em> </em><em>I</em><em> </em><em>had</em><em> </em><em>said</em><em> </em><em>it</em><em> </em><em>was</em><em> </em><em>greater</em><em> </em><em>than</em><em> </em><em>but</em><em> </em><em>it's less</em><em> </em><em>than</em><em> </em><em>because</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>supposed</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>or</em><em> </em><em>greater</em><em> </em><em>than</em><em> </em><em>4</em><em>0</em><em> </em><em>oz</em><em>.</em>

Helen's preferences over cds (c) and sandwiches (s) are given by u(s,
rusak2 [61]
<span>The fact that Helen’s indifference curves touch the axes should immediately make you want to check for a corner point solution. To see the corner point optimum algebraically, notice if there was an interior solution, the tangency condition implies (S + 10)/(C +10) = 3, or S = 3C + 20. Combining this with the budget constraint, 9C + 3S = 30, we find that the optimal number of CDs would be given by 3018â’=Cwhich implies a negative number of CDs. Since it’s impossible to purchase a negative amount of something, our assumption that there was an interior solution must be false. Instead, the optimum will consist of C = 0 and Helen spending all her income on sandwiches: S = 10. Graphically, the corner optimum is reflected in the fact that the slope of the budget line is steeper than that of the indifference curve, even when C = 0. Specifically, note that at (C, S) = (0, 10) we have P C / P S = 3 > MRS C,S = 2. Thus, even at the corner point, the marginal utility per dollar spent on CDs is lower than on sandwiches. However, since she is already at a corner point with C = 0, she cannot give up any more CDs. Therefore the best Helen can do is to spend all her income on sandwiches: ( C , S ) = (0, 10). [Note: At the other corner with S = 0 and C = 3.3, P C / P S = 3 > MRS C,S = 0.75. Thus, Helen would prefer to buy more sandwiches and less CDs, which is of course entirely feasible at this corner point. Thus the S = 0 corner cannot be an optimum]</span>
