If f(x) = x2 – 3x – 40 intersects the x-axis at points A and B, what is the sum of A and B?
Eduardwww [97]

Answer:

3

Step-by-step explanation:

Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.

0 = x^2 - 3x - 40

0 = (x-8)(x+5)

By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.

Can somebody help me with these problems please
const2013 [10]

Answer:

<h3>\huge\sf{Solutions :- }</h3>

<h3>7. Cos Z </h3>

=> Cos theta = Base /Hypotenuse

=> Cos Z = 30/50 => 3/5

★ So, Option <u>B) 3/5 </u> is a correct answer.

_______________________

<h3>8. Cos X </h3>

=> Cos theta = Base/Hypotenuse

=> Cos X = 12/37

★ So, option <u>D)</u><u> </u><u>1</u><u>2</u><u>/</u><u>3</u><u>7</u> is a correct answer.

________________________

<h3>9. Sin Z</h3>

=> Sin theta = Perpendicular/Hypotenuse.

Sin Z = 16/20 => 4/5

★ So, option <u>C)</u><u> </u><u>4</u><u>/</u><u>5</u> is a correct answer

<h3>_____________________</h3>

<h3>10. Sin Z </h3>

=> Sin theta = Perpendicular/Hypotenuse

Sin Z = 48/50 => 24/25

★ So, option <u>A)</u><u>2</u><u>4</u><u>/</u><u>2</u><u>5</u> is correct answer
