Answer:

x = -4/5; x = -2

Explanation:

        15x² + 42x = -24     Add 24 to each side

15x² + 42x + 24 = 0            Remove 3 as a common factor

3(5x² + 14 x +8) = 0        Factor the quadratic

  3(5x+4)((x+2) = 0

=====

5x+4 = 0                              Subtract 4 from each side

    5x = -4                                   Divide each side by 5

     x = -4/5

=====

x+ 2 = 0                              Subtract 2 from each side

    x = -2

The roots are x = -4/5 and x = -2.

The graph is a parabola with x intercepts at x = -4/5 and x = -2.

The rent for an apartment is represented by R(a) = 2.00a + 50.00, where a is the area of the apartment in square feet. The rent
QveST [7]

Answer:

<em>The correct option is:  D)  S(a) = 2.00a + 100.00; shift 50 units up</em>

Step-by-step explanation:

The rent for an apartment is represented by  R(a) = 2.00a + 50.00

Now, the rent increases by $50.00 when the apartment is furnished. So, the rent of a furnished apartment will be:  (2.00a+50.00+50.00) = (2.00a+100.00) dollar

Thus the new function will be:   S(a)= 2.00a+100.00

<u>As the output of the original function is increased by 50.00, so the graph of the original function will shift 50 units upward</u>.

Please help me with the following problem.
Ivahew [28]

Answer:

No, Yes, No, No.

Step-by-step explanation:

"It is not the case that x is equal to 100." This means that x ≠ 100.

"x is not equal to 300." The problem has nothing to do with 300. We know that x ≠ 100, but the fact that x ≠ 300 doesn't prove or deny anything about the statement x ≠ 100.

"x is equal to 100." This is the complete opposite of the original statement! If x = 100, then this completely denies or negates the fact that x ≠ 100.

"It is not the case that x is equal to 400." Again, 400 has nothing to do with the statement x ≠ 100, so the statement neither proves nor denies the statement x ≠ 100.

"x is equal to 300." Same story: 300 has nothing to do with x ≠ 100, so it doesn't change anything about x ≠ 100.
