If the graph of the function f (X) is represented in the attached figure, which of the graphs presented in the options represent
Ahat [919]

Answer:

  • A. g(x) = 1/3x + 1

Step-by-step explanation:

<u>The line has points:</u>

  • (0, -3) and (1, 0)

<u>It has y-intercept b = -3 and a slope:</u>

  • m = (0 + 3)/1 = 3

<u>The equation:</u>

  • f(x) = 3x - 3

<u>It inverse is (let's call it g(x)):</u>

  • x = 3y - 3
  • 3y = x + 3
  • y = 1/3x + 1
  • g(x) = 1/3x + 1

The slope of the inverse function is 1/3 and the y-intercept is 1

The graph reflecting this is A

Solve for the roots in simplest form using the quadratic formula:<br>4x2 + 21<br>20x​
Artyom0805 [142]

Answer:

(0,0) and (-530,0)

Step-by-step explanation:

If you have to use the quadratic formula, you need to know your A, B, and C values. Your A value is 4, your B is 2120, and your C value, or constant, appears to be zero. Then you need to plug these values into the quadratic formula to get 0 and -530. This would make your roots to be at points (0,0) and (-530,0).

I WILL AWARD BRAINLIEST!! PLEASE HELP!!
Anastasy [175]

Answer:

m∠EBC=65° 15' and AC=20in

Step-by-step explanation:

Given:

AB≅BC

AE=10in\\m\angle FEC=90\\m\angle ABC=130\°30'

From the given Data, we can conclude the following:

1. Since two sides of the triangle ABC are congruent, therefore its an isosceles triangle.

2. m\angle FEC=90°. This shows that the line BE is perpendicular to AC. By property of isosceles triangle, the line which passes from the vertex of the largest angle of triangle and cuts the opposite side(base) perpendicularly is the perpendicular bisector of the side and angle bisector of the angle.

∴  m\angle EBA\ ≅m\angle EBC    [ Definition of Angle bisector]

m\angle ABC=130\°30'

m\angle EBC=\frac{m\angle ABC}{2}=\frac{130\°30'}{2}=65\°15'

m\angle EBC=65\°15'

∴AE=EC       [ Definition of perpendicular bisector]

AE=EC=10in

AC=AE+EC

AC=10+10=20in

AC=20in
