Answer:

  • x² - 8x + 12
  • x³ + 2x² - 15x - 36
  • x³ -2x² - 15x

Step-by-step explanation:

#1) Find the polynomial with roots at 2 and 6

  • (x -2)(x - 6) = x² - 8x + 12

#2) Find the polynomial with a double root at -3 and another root at 4

  • (x+3)(x+3)(x-4) = (x²+6x+9)(x-4) = x³ + 2x² - 15x - 36

#3) Find the polynomial with roots 0, -3 and 5

  • (x -0)(x+3)(x-5) = x(x²-2x - 15) = x³ -2x² - 15x

) What would the value of c be when
jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

\frac{18}{20}c-250=-40

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210

Multiplying by 20 on both sides

20*\frac{18}{20}c=210*20\\18c=4200

Dividing both sides by 18

\frac{18c}{18}=\frac{4200}{18}\\c=233.3333

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3

Find the slope and the y-intercept of the graph of y+1=4/3x.
riadik2000 [5.3K]

Answer:

Slope = 4/3x; y-intercept = -1

Step-by-step explanation:

y + 1 = 4/3x

You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept

y + 1 = 4/3x

Subtract one from both sides

y + 1 - 1 = 4/3x - 1

y = 4/3x - 1

Now that we have the equation, you can now find the slope and y-intercept

y = mx + b; m is the slope and b is the y-intercept

So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
