If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f-g) (x).

Eduardwww [97]

Answer:

x² + 8

Step-by-step explanation:

note (f - g)(x)

= f(x) - g(x)

= 2x² + 1 - (x² - 7) = 2x² + 1 - x² + 7 = x² + 8

Find the coordinates of x−intercept and of y−intercept of the line. y=−3x−9

My name is Ann [436]

Answer:

(-3, 0), (0, -9)

Step-by-step explanation:

x-intercept: Let y = 0 and find x: 0 = -3x - 9), or 3x = -9. Then x = -3, and the x-intercept is (-3, 0).

y-intercept. Let x = 0 and find y. y = -3(0) - 9 = -9. The y-intercept is (0, -9).

Write the slope-intercept form of the equation of the line through the given points.

9966 [12]

Answer:

y = 7x +2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 1, - 5 )

m = $\frac{-5-2}{-1-0}$ = $\frac{-7}{-1}$ = 7

the line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = 7x + 2 ← equation of line
