How many solutions does the system have?

Hatshy [7]

Answer:
A:One Solution
Step-by-step explanation:
First substitute the y in the first equation with the second equation to get
-2x-4=3x+3
since theres a variable of both sides, you subtract the variable with the least coefficient, in this case, you add 2x to both sides to get
-4=5x+3
subtract the constant on both sides to get
-1=5x
divide both sides by 5
x= -0.2 or -1/5
it's A, one solution

PLEASE HELP!!! Write the expression as a single logarithm.<br> 3 log(4) + log(7)

anygoal [31]

Answer:

log (448)

Step-by-step explanation:

3 log(4) + log(7)

We know that a log b = log b^a

3 log(4) + log(7)

log 4^3 + log 7

log 64 + log 7

We know that log a + log b = log (a*b)

log (64 *7)

log (448)

While Brendan is vacationing with his family at the cabin, they take a motorboat on the river. The motorboat travels

taurus [48]

Part 1: The speed of the boat traveling downstream is $(18+w)$ miles per hr.

The speed of the boat traveling upstream is $(18-w)$ miles per hr.

Part 2: The speed of the current is 4 miles per hour.

Explanation:

Part (1): The motorboat travels 18 miles per hour in still.

Let w represents the speed of the current.

When the boat travels downstream, the speed of the current will get added to the speed of the boat.

Thus, the expression can be written as $(18+w)$ miles per hr

Hence, the speed of the boat traveling downstream is $(18+w)$ miles per hr.

When the boat travels upstream, the speed of the current will get subtracted to the speed of the boat.

Thus, the expression can be written as $(18-w)$ miles per hr.

Hence, the speed of the boat traveling upstream is $(18-w)$ miles per hr.

Part (2): The boat travels 49 miles upstream in the same time it takes to travel 77 miles downstream.

The distance formula is given by $distance $=$ speed $\times$ time$

Substituting, we have,

$49=(18-w)t\\49=18t-wt$ ---------------(1)

$77=(18+w)t\\77=18t+wt$ ---------------(2)

Solving using elimination method,

$49=18 t-w t\\77=18 t+w t\\-------\\126=36t$

Dividing both sides by 36, we have,

$t=3.5$

Substituting $t=3.5$ in $49=18 t-w t$ , we get,

$49=18(3.5)-w (3.5)\\$

$49=63-3.5w\\$

$-14=-3.5w\\$

$4=w$

Thus, the speed of the current is $w=4$ miles per hour.
