PLEASE HELP FAST!! ILL MARK AS BRAINLIEST!! Graphing is the best choice when solving for the following system:

1 answer:

8 0

False. You can find the solution more quickly by solving the system algebraically.

-4x + 2y = 18

Since y=-3x+4,
-4x + 2(-3x+4) = 18
-4x - 6x + 8 = 18
-10x = 10
x = -1
y = -3x+4 = 7

A cable car can safely carry n people thete are alreafy 3/4n people on the cable car only 12 more people can board the cable car

ipn [44]

Answer: 48 people.

Step-by-step explanation:

1. You know that $n$ represents tha number of people that the cable car can safely carry.

2. If you know that there are $\frac{3}{4}n$ and only 12 more people can board it before it becomes unsafe, you can write the following expression:

$n=\frac{3}{4}n+12$

3. Now, you must solve for $n$ .

4. Then, the number of people that the cable car safely carry is:

$n-\frac{3}{4}n=12\\\frac{1}{4}n=12\\n=12*4\\n=48$
