Answer:

f(x)= x^3+x^2-14x-24

Step-by-step explanation:

Since the zeroes are -3, -2, 4, the factored form of the polynomial must be:

(x+3)(x+2)(x-4)

If these are multiplied:

(x^2+5x+6)(x-4)

Then multiplied again

x^3-4x^2+5x^2-20x+6x-24

Then like terms are combined,the answer is

x^3+x^2-14x-24

John drives to the beach which is 270 miles away from his house. In 2 hours, he drives 120 miles. If he continues at that speed,
Karolina [17]
The answer is 4.5 hours.
 
120 miles/2 hours = 60 mph
270-120 = 150 miles
150 miles/60 mph = 2.5 hrs

2 hrs+2.5 hrs = 4.5 hours for the whole trip

Line AB goes through the points A (0, –4) and B (6, 2). Which equation represents line AB?
insens350 [35]

Answer:

Option C) y + 4 = x

Step-by-step explanation:

We are given the following information in the question:

Line AB goes through the points A (0, –4) and B (6, 2).

We can use the two-point form of equation of straight line.

The equation of line is given by:

(y-y_1) = \displaystyle\frac{y_2-y_2}{x_2-x_1}(x-x_1)

where, (x_1,y_1), (x_2.y_2) is the point through which the line passes.

The equation of line is:

(y+4) = \displaystyle\frac{2+4}{6-0}(x-0)\\\\(y+4)= x\\y = x-4

Thus, the equation of line AB is given by Option C) y + 4 = x

Three pounds of lawn seed covers 1800 square feet how many 4 pound bags are needed to cover 8400 square feet.
VikaD [51]
You need to find the unit rate of 3 : 1800 first by dividing 1800 and 3

1800 ÷ 3 = 600

So this means for every 1 pound bag it covers 600 square feet. You now need to multiply 600 and 4 to see how many square feet 4 pounds cover.

600 × 4 = 2400

So each 4 pounds covers 2400 sq ft. Now you have to divide 8400 and 2400 to find how many bags of 4 pounds you need

8400 ÷ 2400= 3.5

You need 3.5 bags of 4 pounds.
Technically you would need 4 bags because you’d have to round it up.

Hope this helps you!! :)

Use the elimination method to solve the system of equations
Lady bird [3.3K]

Answer:

D

Step-by-step explanation:

2x + 3y = 18

3x - 3y = 12

the 3y and -3y cancel and you add the other like terms

5x = 30

x = 6

plug x back into any of the equations

2(6) + 3y = 18

12 + 3y = 18

3y = 6

y = 2

answer is (6,2)
