Answer:

1. -3

2. 7

3. -2

4. 3

Step-by-step explanation:

1. idk

2. 3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get

3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4 .2b/.2=b 1.4/.2=7 so b=7

3. 4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2

2.6y=-5.2 divide both sides by 2.6 to get y=-2

4. 7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7

5c=-15 divide both sides by 5 getting c=3

At what value of x does the graph of the following function F(x) have a

tankabanditka [31]

Given:

The function is

$F(x)=\dfrac{1}{x+2}$

To find:

The vertical asymptote of the given function.

Solution:

Vertical asymptote are the vertical line passes thought the values for which the function is not defined.

To find the vertical asymptote, equate the denominator equal to 0.

We have,

$F(x)=\dfrac{1}{x+2}$

Denominator is (x+2).

$x+2=0$

$x=-2$

The vertical asymptote is $x=-2$ .

Therefore, the correct option is B.

If you have a demand function of Qd=48-9P and a supply function of Qs=-12+6P,

jenyasd209 [6]

Answer:

The equilibrium quantity is 26.4

Step-by-step explanation:

Given

$Q_d = 48 - 9P$

$Q_s = 12 + 6P$

Required

Determine the equilibrium quantity

First, we need to determine the equilibrium by equating Qd to Qs

i.e.

$Q_d = Q_s$

This gives:

$48 -9P = 12 + 6P$

Collect Like Terms

$-9P - 6P = 12 - 48$

$-15P = -36$

Solve for P

$P = \frac{-36}{-15}$

$P =2.4$

This is the equilibrium price.

Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:

$Q_d = 48 - 9P$

$Q_d = 48 - 9 * 2.4$

$Q_d = 26.4$

<em>Hence, the equilibrium quantity is 26.4</em>

Hunter-Best [27]

Answer:

13 * r

Step-by-step explanation:

If each member sells the same number of raffle tickets, then 13r would show that each of the 13 members will have sold <em>r</em> raffle tickets each. The expression is multiplication.
