Answer:

<h2>steps A & B</h2><h2 />

Step-by-step explanation:

5x + 9 = 2x - 3

subtract 2x from both sides

5x - 2x + 9 = 2x - 2x - 3

simplify:

3x + 9 = -3

subtract 9 from both sides:

3x + 9 - 9 = -3 - 12

simplify:

3x = -12

divide 3 on both sides:

<u>3x</u> = <u>- 12 </u>

3        3

simplify:

x = -4

Explain how to solve 3^x-4=6 using the change of base formula log base b of y equals log y over log b. include the solution for
Alexxandr [17]

Answer:

x = log 10/log 3

Step-by-step explanation:

3^x - 4 = 6

3^x = 10

We take log base 3 of both sides since log_3 3^x is simply x.

log_3 3^x = log_3 10

x = log_3 10

We have an answer for x, but it is a log base 3. We want log base 10.

Now we use the change of base formula.

log_b y = log y/log b

x = log 10/log 3

Trava [24]

Answer:

Option C.

Step-by-step explanation:

It is given that planes A and B intersect in line s.

It means, all points lie on the line s must be lie on both plane A and B because s is the line of intersection of both plane A and B.

It is given that V is a point on line s.

Since, the point V lies on line s, therefore it is also lies on both plane A and B.

Hence, the correct option is C.

HACTEHA [7]

Answer:

x=9, y=10. (9, 10). The two numbers are 9 and 10.

Step-by-step explanation:

3x+5y=77

x+y=19

------------------

3x+5y=77

-3(x+y)=-3(19)

---------------------

3x+5y=77

-3x-3y=-57

-------------------

2y=20

y=20/2

y=10

x+10=19

x=19-10

x=9
