Answer:

C. y =  -  \frac{1}{4} x - 2

Step-by-step explanation:

To find slope using coordinates, use the formula above.

(4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → -  \frac{1}{4}

Now, using the y = mx + b formula, plug in -  \frac{1}{4} as m (slope) and either coordinate as the x and y values. It looks like this:

- 3 =   - \frac{1}{4}(4)  + b

To solve for b, continue to use PEMDAS.

- 3 =   - \frac{1}{4}(4)  + b→ - 3 =  - 1 + b→ - 2 = b

Now use m and b to solve for your equation:

y =  -  \frac{1}{4} x - 2

The answer is C.

8/2=6/n+4 Solve for n
Reptile [31]

Answer:

No solution (because the n's cancel out!)

Step-by-step explanation:

Let's solve your equation step-by-step.

8

2

=

6

n

+4

Multiply all terms by n and cancel:

8n

2

=6+4n

4n=4n+6(Simplify both sides of the equation)

4n−4n=4n+6−4n(Subtract 4n from both sides)

0=6

Answer:

No solutions.

The population in the United States is approximately 3.2× 10^8. A total of 1.4 × 10^6 people immigrated to the United States. De
kodGreya [7K]

Answer:

3.186 x 10^8

Step-by-step explanation:

3.2× 10^8 = 320,000,000

1.4 × 10^6 = 1,400,000

320,000,000 - 1,400,000 = 318,600,000

318,600,000 = 3.186 x 10^8

   - you get to the power of eight, by counting the amount of spaces the decimal moved over (moving to the left increase, but right decreases)
