Definitely the correct answer is D. You need to expand the product 5(x-2), and then to group all x terms together and all constants together.

The bank charged TENLEY $30 fee because her balance dropped below $0. She knows that she currently has an outstanding charge of

Korolek [52]

Answer:

Tenley has to deposited any amount from $50 and above.

Step-by-step explanation:

From the above question, we can deduce that if your bank balance is below 0, = - , you would be charged $30

Hence,

First she has to pay the bank charges of $30, and to prevent the outstanding charge of $19.95 for generating about charge she has to deposit any amount above $19.95

The amount she has to deposit is

$30 + (x > $19.95)

Assuming x is $20 and above

= $30 + $20 = $50

Hence, Tenley has to deposited any amount from $50 and above.

35 solve the following syste

blondinia [14]

Part A: The solution is $(-0.923,5.692)$

Part B: The point $(3,7)$ is not in the solution set.

Explanation:

Part A: The given inequalities are $3 x+4 y>20$ and $x$

The solution can be determined by solving the two inequalities by substitution method.

Changing inequalities to equality, we have,

$x=3 y-18$ and $3 x+4 y=20$

Let us substitute $x=3 y-18$ in the equation $3 x+4 y=20$ , we get,

$3 (3y-18)+4 y=20$

$9y-54+4y=20$

$13y=74$

$y=5.692$

Substituting $y=5.692$ in $x=3 y-18$ , we get,

$x=3 (5.692)-18$

$=17.076-18$

$x=-0.923$

Thus, the solution set is $(-0.923,5.692)$

Part B: Now, we shall determine whether the point $(3,7)$ is in the solution set.

Let us substitute the point $(3,7)$ in the inequalities $3 x+4 y>20$ and $x$ , we get,

$3 (3)+4 (7)>20$

$9+28>20$

$37>20$

Also, substituting $(3,7)$ in $x$ , we get,

$3$

$3$

$3$

Since, the point $(3,7)$ does not satisfy one of the inequality $x$ , the solution set does not contain the point $(3,7)$

Thus, the point $(3,7)$ is not in the solution set.
