Answer:

m = -2/3

Step-by-step explanation:

m = slope

$m = \frac{y2 - y1}{x2 - x1}$

m = -3 -1/ 3 - (-3)

m= -4/ 6

m= -2/3

What are the solutions to 16x^2-12x=54? Select all the apply.

lesya692 [45]

Answer:

-3/2 or 9/4

Step-by-step explanation:

16x^2 - 12x = 54

Now, we take 54 to the left side. It leads the right side to become "0". As 54 is a positive, it will negative as we change the side.

16x^2 - 12x - 54 = 0

Dividing both the sides by 2, we get,

8x^2 - 6x - 27 = 0

Now, we use factorization method,

8x^2 + 12x - 18x - 27 = 0

or, 4x (2x + 3) - 9 (2x + 3) = 0

or, (2x + 3) (4x - 9) = 0

Now, 2x + 3 = 0; or, 4x - 9 = 0

2x = - 3; or, 4x = 9 (changing the sides)

or, x = - (3÷2); or, x = (9÷4)

Therefore, the solution set for x is either - 3/2 or 9/4

A car rental agency advertised renting a car for $24.95 per day and $ 0.34 per mile. If Kevin rents this car for 2 days, how ma

love history [14]

Answer:

441 miles

Step-by-step explanation:

Write and solve an inquality to answer this question:

($24.95/day)(2 days) + ($0.34/mile)x ≤ $200

The first term becomes $49.30; the second term $0.34x; their sum must be ≤ $200.

More concisely, 49.30 + 0.34x ≤ 200.

Isolate x by subtracting 49.30 from both sides:

0.34x ≤ 150.10.

Divide both sides by 0.34:

x ≤ 150.10/0.34, or 441.47 miles. You must round this off to the nearest whole mile, which would be 441 miles.
