Answer:

y-intercept: 3

x-intercept: 1

Step-by-step explanation:

To find x-intercept:

1. make y equal to 0, leaving 9x=9

2. divide both sides by 9

3. x=1

To find y-intercept:

1. make x equal to 0, leaving 3y=9

2. divide both sides by 3

3. y=3

Hope this helps!

Hat is the equation of the quadratic function with a vertex at (2,–25) and an x-intercept at (7,0)?
Novosadov [1.4K]

Answer:

y = x² - 4x - 21

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 25), thus

y = a(x - 2)² - 25

To find a substitute (7, 0) into the equation

0 = a(7 - 2)² - 25 = a(5)² - 25 = 25a - 25 ( add 25 from both sides )

25a = 25 ( divide both sides by 25

a = 1, thus

y = (x - 2)² - 25 ← in vertex form

Expand and simplify

y = x² - 4x + 4 - 25

y = x² - 4x - 21 ← in standard form

Find the measures of a positive angle and a negative angle that are coterminal with each given angle. Part 2.
Ratling [72]

Answer:

8. -385°, 335°

9. -30°, 330°

Step-by-step explanation:

8. θ = -25°

-25-360 = -385°

-25+360 = 335°

9. θ = -390°

-390+360 = -30°

-30+360 = 330°
