Is 4 + 15x = 49 true? How do you know?

Mathematics
1 answer:
jekas [21]3 years ago
5 0

Answer:

Yes it is true.

Step-by-step explanation:

If you go on and solve for x, you get 3. I got this by subtracting the 4 from both sides, then getting 15x=45. Then I divided both sides by 15 and got x=3. If you plug that in, you get 4+45=49. This proves to be true.

24. Find the area of the shaded region:
Monica [59]

Answer:

A = 5x³ + 17x² - 35x - 30

Step-by-step explanation:

the shaded area (A) is calculated as

A = outer area - inner area

   = (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis

   = 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)

  = 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms

  = 5x³ + 17x² - 35x - 30

<u>Given line:</u>

  • - x + y = - 5

<u />

<u>The y-intercept is the point when x = 0:</u>

  • 0 + y = - 5
  • y = - 5

The point is (0, - 5)

<u />

<u>The x-intercept is the point when y = 0:</u>

  • - x + 0 = - 5
