Answer:

Option 1 - \log_a (3c-d)=2b+1

Step-by-step explanation:

Given : Equation a^{2b+1}=3c-d

To find : Which of the following is the equation ?

Solution :

Equation a^{2b+1}=3c-d

Taking log both side,

\log (a^{2b+1})=\log (3c-d)

Apply logarithmic property, \log a^x=x\log a

(2b+1)\log (a)=\log (3c-d)

(2b+1)=\frac{\log (3c-d)}{\log a}

Apply change the base rule, \frac{\log _a x}{\log _a y}=\log_y x

(2b+1)=\log_a (3c-d)

So, the required equation is \log_a (3c-d)=2b+1

Therefore, option 1 is correct.

Plz help me this question plz plz help plz help me all four of them plzzzz
garik1379 [7]

Answer:

10) The equation of a line parallel to y=-3 passing through the coordinate (2,6) is y=6

11) The equation of a line perpendicular to y=-3 passing through the coordinate (2,6) is x=6

12) The equation of a line parallel to x=4 passing through the coordinate (-2,3) is x=-2

13) The equation of a line perpendicular to x=4 passing through the coordinate (-2,3) is y=3

Step-by-step explanation:

For any line parallel to X-axis the equation we have

y=a

where a is the y coordinate.

∴  The equation of a line parallel to y=-3 passing through the coordinate (2,6) is y=6

For any line parallel to Y-axis the equation we have

x=b

Where b is the x coordinate.

∴ The equation of a line parallel to x=4 passing through the coordinate (-2,3) is x=-2

For any line perpendicular to X-axis is parallel to Y axis therefore the equation we have

x=b

∴ The equation of a line perpendicular to y=-3 passing through the coordinate (2,6) is x=6

For any line perpendicular to Y-axis is parallel to X axis therefore the equation we have

y=a

∴  The equation of a line perpendicular to x=4 passing through the coordinate (-2,3) is y=3

Malik works at a hardware store for $12 per hour and as a lifeguard for $18 per hour. He needs to earn at least $280 per week, b
Arte-miy333 [17]

Answer:

The system of inequalities is equal to

12x+18y\geq280

x+y\leq 20

Step-by-step explanation:

Let

x-----> the number of hours that Malik works at a hardware store

y-----> the number of hours that Malik works as a lifeguard

we know that

12x+18y\geq280 -----> inequality A

x+y\leq 20 -----> inequality B

Using a graphing tool

The solution is the shaded area

see the attached figure

Pls helppppp and explain how to answer

Well, the place is charging him 115/hr
and he's booked it for 6hrs

how much is going to be his cost? well \bf \cfrac{115}{hr}\cdot 6hr\implies 690

now, there will be 14 teams playing, so... if we divide 690 evenly among the 14 teams, that means each team will need to pay 690/14 about 49.28571 or 49 bucks and 29 cents about

now, if each team pays that much, they'll cover 690, so Dylan has his cost covered, however, for a profit, a profit is surplus, so, in order to make surplus income, or profit, he'll need to charge "more than" 49.29
or he needs to charge "x", whilst    x > 49.29
