The sum of a number and 3 times its reciprocal is -4.Find the number

Butoxors [25]

Answer:

x = -1 or x = -3

Step-by-step explanation:

x + 3/x = -4

x² + 3 = -4x

x² + 4x + 3 = 0

(x + 1) (x + 3) = 0

x = -1 or x = -3

check: (-1) + (3/-1) = -1 - 3 = -4

(-3) + (3/(-3)) = -3 -1 = 14

Can someone help me with a question!?!?

Len [333]

If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).

Now if a is a big number, the parabola will become narrower.

So it will stretch vertically and become narrower.

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (200, 14)

Point (225, 16)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{16-14}{225-200}$
[Fraction] Subtract: $\displaystyle m=\frac{2}{25}$

Find the amount financed and the finance charge in dollars for the following problem. Choose the correct answers.

diamong [38]

$350 * 30/100 = $ 105 which is down payment.

$350 - $105 = $245 which is left.

But he will pay $24.50 * 12 = $294 instead.

$294 - $245 = $49

He will pay $49 more.

He paid $105 as down payment and will pay $294 more with 12 months.

Total will be $105 + $294 = $399
