If you divide a polynomial f(x) by the factor (x - 4), the remainder will be equal to f(-4). true or false ?
lorasvet [3.4K]

Answer:

<h3>FALSE</h3>

Step-by-step explanation:

Given the polynomial f(x)  divided by  x-4

To check whether the remainder will be equal to f(-4), we need to get whether the value of x is -4 if we set x-4 to zero as shown;

x- 4 = 0

Add 4 to both sides

x - 4 + 4 =  0+4

x = 4

<em>Since the value of x is 4 not -4 hence the remainder will NOT be equal to f(-4). The answer is false</em>

According to the line of best fit, what is the best estimate of projected sales in thousands of dollars for 2018?
Iteru [2.4K]
About $43,000 because if you look on the graph, look for 2018 and go up until you meet the line. Then, using that, you can move left to the sales indication. The line hits 2018 between 40,000 and 45,000, so it is $43,000.

2/5 + 1/6 =<br> please show work thanks
Genrish500 [490]

Answer:

17/30

Step-by-step explanation:

2/5 + 1/6 = 17/30

Make them easier to add by making them have the same denominator.

2/5 = 12/30

1/6 = 5/30

12/30 + 5/30 = 17/30

In triangle JKL, if line JK is equal to line JL, angle J equals 23x-4, angle K equals 4x-1, and angle L equals 9x-31, find x and
hjlf
Based on the information about side JK = side JL, then we know it is at least an isosceles triangle. Furthermore, ∡K =∡L because they are the base angles in an isosceles triangle.
Equation: 4x - 1 = 9x - 31
Solved: x = 6
Angle measures: ∡J = 23(6) - 4 = 138 - 4= 134
                            ∡K = ∡L = 23

2 Determine whether the table represents a linear relationship. If so, state the slope of
yarga [219]

Answer:

  • Tables A and B represent linear relationship

-------------------------

<h3>Table A</h3>
  • x = 2, 3, 4, 5                  Difference is 1
  • y = 14, 21, 28, 35           Difference is 7
  • This is linear and the slope is 7

<h3>Table B</h3>
  • x = -2, -1, 0, 1                  Difference is 1
  • y = 10, 5, 0, -5                Difference is - 5
  • This is linear and the slope is - 5

<h3>Table C</h3>
  • x = 2, 3, 4, 5                  Difference is 1
  • y = 48, 72, 90, 114         Difference is inconsistent
  • This is not linear
