Which of the following is a factor of f(x) = 3x3 + 8x2 − 87x + 28? (5 points)

N76 [4]

Answer

(x - 4)

Step by step explanation

To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

Here (x - 4) is a factor.

Therefore, x = 4

when we plug in x = 4 in the given expression, we get zero.

Let's check it out.

3(4)^3 + 8 (4)^2 - 87(4) + 28

192 + 128 - 348 + 28

348 - 348

The answer is (x - 4)

Thank you.

How do i write an equation in point-slope form for a horizontal line that passes through(4, –2)??

givi [52]

Answer:

$y = -2$

Step-by-step explanation:

Given

Horizontal Line

$(x_1,y_1) = (4,-2)$

Required

Determine the equation

The equation is calculated using:

$y - y_1 =m(x-x_1)$

Where

$m = slope$

Because the line is a horizontal line, then:

$m = 0$

Substitute 0 for m and values for x1 and y1 in $y - y_1 =m(x-x_1)$

$y - (-2) = 0(x -4)$

$y +2 = 0(x -4)$

$y +2 = 0$

Subtract 2 from both sides

$y +2-2 = 0-2$

$y = -2$

Hence, the equation is: $y = -2$

How many 7-digit numbers are there where all the digits are different and in increasing order? for example, the numbers 1345689

frutty [35]

For this problem,we use the Fundamental Counting Principle. You know that there are 7 digits in a number. In this principle, you have to multiply the possible numbers for every digit. If the first number cannot be zero, then there are 9 possible numbers. So, the value for the first digit is 9. The second digit could be any number but less of 1 because it was used in the 1st digit. So, that would be 10 - 1 = 9. The third digit must be the value in the second digit less than 1. That would be 9 - 1 = 8. And so on and so forth. The solution would be:

9×9×8×7×6×5×4 = 544,320 7-digit numbers

Part A: Eveline rented a car at $180 for 4 days. If she rents the same car for 9 days, she has to pay a total rent of $325. Writ

QveST [7]

Answer:

Step-by-step explanation:

Part A

We will use the slope intercept form of the line and then convert later.

Equation

y = mx + b is the general form

Givens

Two data points

(4,180)

(9,325)

Solution

325 = 9x + b

<u>180 = 4x + b</u> Subtract

145 = 5x Divide by 5

145/5 = 5x/5 Do the division

29 = x This represents the cost / day

180 = 4x + b Substitute x = 29 to find b

180 = 4*29 + b Combine

180 = 116 + b Subtract 116 from both sides.

180 - 116 = b

64 = b

Solution for y = mx + b

y = 29x + 64

In Standard form this is

- 29x + y = 64 But the first number must be plus

29x - y = - 64 <<<< Answer A

Part B

y = 29x + 64

f(x) = 29x + 64

Part C

The graph is shown below. Various points are filled in using y = 29x + 64. The y intercept is (0,64) which is labeled. Let x = 1 , 2, 3, 4, ... 10 (which is arbitrary). This may be more easily done on a spreadsheet if you know how to use one to make graphs.
